Holidays at PhD Talk

on Sunday, December 22, 2013

Happy Holidays, dear readers!

I hope you all can take some rest, let go of your research, and recharge your batteries. I'll be spending time with my family in law, trying to talk a lot on Skype with my family and friends in Belgium (missing them gets just a little worse over cozy holidays), and trying to find some holidays spirit while the sun burns (we might schedule a trip to one of the higher towns (> 3000m above sea level), so I get a dose of cold weather to pair with the holidays.

The regular posts will resume on January 5th.

I'm delighted and flattered and happy and more to see how PhD Talk has been growing over the past year. I'm still searching for a direction for PhD Talk now that I finished the PhD - but I decided to just let the topics flow as my life and interests flow, instead of trying to pin myself down. As I evolve, my writing evolves, my academic life evolves and it would be unnatural if the contents of this blog wouldn't evolve with me.

2014 promises to be another year full of challenges: my first year in which I juggle my research position in Delft with my professorship in USFQ - let's see how that goes (and let's see how I do with teaching 3 new courses in 1 semester *__* ).

PhD Talk for AcademicTransfer: The Curious Case of the Academic Nomads

on Thursday, December 19, 2013
This post is part of the series PhD Talk for AcademicTransfer: posts written for the Dutch academic career network AcademicTransfer, your go-to resource for all research positions in the Netherlands.

These posts are sponsored by AcademicTransfer, and tailored to those of you interested in pursuing a research position in the Netherlands.

If these posts raise your interest in working as a researcher in the Netherlands, even better - and feel free to fire away any questions you might have on this topic!


Life in academia can take you from one temporal contract in country A to another challenge in country B, with stops for fieldwork in countries C and D and maybe a few months as a visiting scholar in country E. Most academics are hired for a period of 2 to 4 years, depending on the type of work that they might do.

I like to call those that hop from country to country as their career meanders over the years the academic nomads.

Most of us might not be expecting this ever-evolving and ever-traveling path when we start our careers in academia. But then research life happens and you get to know people and opportunities come up, and before you know you're boxing up your life for the umptieth time.

That happened to me. As a student, I enjoyed going on exchanges during the summer holidays, and I was planning an extra post-graduate year after my engineering studies, but I thought I'd try and score a job at Belgium's biggest prefab concrete fabricator, conveniently located in my beloved hometown of Lier, Belgium. But then I received this email to notify me that, with my good grades, I could apply for scholarships to study in the US. And in the process I thought, well, why not set my mind on going on for the PhD afterwards? With 2 prestigious scholarships in my pocket, I set sail for Atlanta, and started my second Masters' degree in Fall 2008. And then the financial crisis hit, and soon it became clear to me that securing funding for a PhD would be difficult. I knew that I wanted to stay in structural concrete research, preferably a topic on shear, torsion or second-order-effects in columns, and I started to look for openings. I learned about the new project in Delft, applied, and got accepted by the end of my first semester at Georgia Tech. I rolled up my sleeves, studied a little harder, got my Masters' by August, and started in Delft in September, leaving a then-boyfriend behind in the US. He finished his PhD and went to work for the industry in the US, and then I finished my PhD. We had to look for a place where both of us could find a job, and so ended up in Ecuador. At the same time, I could secure a part-time position in Delft, to keep involved in research. Don't ask me how often I've moved over the past years...

Very often, I read stories of fellow academics who move from continent to continent, as they amass scholarships, short-term job contracts and the like.

If you are considering graduate school, you might as well get yourself prepared for this roller-coaster of moving from place to place. And now that we're at it, why not consider going to the Netherlands for your PhD? It wasn't part of my original plan, but it worked out like a charm.

My main message is: be prepared for gradually turning into a nomad! You might just get lured into this lifestyle while you follow your excitement over projects....

If you notice that you are headed for a life as an academic nomad, then you might want to take the following tips into account:

1. Go digital


Books are heavy, so to avoid having to move by container all the time, try to buy as many books digital as you can. Similarly, get your music as digital files, scan your important notes, and go paperless as much as you can.

2. Fly the same airline

As an academic nomad, you will be flying a lot. Pick an airline, and be loyal to them in return for getting miles. Mileage status will give you extra perks over time, and you can turn them in for a free flight.

3. Sort out your clutter

Unless you want to keep a room filled with boxes in your parents' house "until you get a tenured position in your homecountry", you might just need to sort through all your stuff and sell/thrash/recycle what you don't need anymore.

4. Identify a few items that you value

Even though the hardcore minimalists might disagree, I think it's perfectly OK to have a couple of items that you cling to, and that you use to make your new place truly feel like you home. I have a number of totally random items (a giant wall backdrop, my "pace" flag, 2 sets of matryoshkas, a teddybear and a small stone for putting essential oils) and my cat that I drag along with my wherever I go. These little things just make me feel more comfortable wherever I try to settle for a little while.

5. Embrace the best of every country

If you move, you get a culture shock. That's the plain truth. But in order to overcome the I-hate-this-place phase, you'll have to learn to find the best in every country. Go out and explore the natural beauty of your new place, visit local festivities and events, and try to bond with the locals. Before you know, you'll have yet another country that you'll miss when you're not there...

How Successful Women Balance Work and Life

on Tuesday, December 17, 2013
Today, we are looking at the topic of balance and employment. Work-life balance and staying sane in graduate school are topics that I write about frequently here at PhD Talk, so I was glad when Ashley Jones pitched me for a guest post on combining work and life. While this post is tailored to women, I think the ideas in here are valid for all of us - regardless of our gender

As women move through their live, the approach to finding a balance between work and life is becoming an important issue in contemporary life. Women are rightfully taking on many of the most demanding occupations that society can offer and as a result are increasingly responsible for a majority of the most difficult jobs in the country.

Among this subset of skilled workers, women with doctoral degrees are particularly accustomed to work schedules that leave little time for personal space and reflection. Accordingly, it may be of benefit to list just some of the ways that successful women are striking balances between their careers and their personal lives.

1. Meditation
Long an activity that stood at the forefront of Eastern philosophies, meditation is now recognized by many health professionals as an engaging way to promote self-care. By reducing rumination and other forms of anxious thinking, meditation is a particularly apt way for successful women to direct the watercraft of their days into calmer waters. Numerous practitioners of meditation find that the activity becomes an anchor of calm in their busy lives and leads to a greater sense of focus and overall health. Whether done by oneself or with the help of experts, meditation is only likely to gain more followers in the future.

2. Creative Work
Even when free-time can seem limited, finding a few minutes a day to do creative work can be a major way to promote a work-life balance. For example, writing fiction or personal essays can provide an outlet for experience that can feel immensely rewarding; even finding an hour a day to write can bring numerous benefits. Other forms of creative work such as painting and sculpture can also provide relief from the stresses of work and create a sense of happiness and satisfaction both on and off the job.

3. Life-long Learning
Learning about new ideas in life doesn't have to stop once a doctoral thesis is finished. Finding area colleges that offer evening or weekend classes are great ways to keep the mind sharp and skills current. By choosing a subject that’s unfamiliar but interesting, successful women can often find that while knowledge is always changing, learning is a life-long process. As a means for socializing, taking classes can also introduce non-traditional students to new friends and even mentors. For many people, a love of learning can become a daily practice even after they’re experts in a field.

4. Love of Travel
Sometimes learning to take time for oneself is among the most important lessons anyone can gain in life. For example, taking a period of time to examine another country will often teach a person more about different cultures than anything else, and travel can often act as a sort of deep breath from our careers. As a field of interest, travel has become one of the most popular ways to understand ourselves and others, and its proponents often wouldn't trade the experiences they've gained in foreign countries for the world.

Ashley Jones is the author of many articles with resources for professional women. Her recent work is on the Best Online Master of Science in Education (MSEd) Degree Programs for women who want to work while learning

Silver Linings: the Fruits of Ecuador

on Sunday, December 15, 2013
One way in which I am enjoying life in Ecuador, is by trying out all the exotic and rare fruits this country has to offer. Generally, there are the exotic fruits from the coast, that grow in the hot and humid climate of Ecuador's coast, and then there are the fruits from the highlands, which are very difficult to find in Europe, because of the unique combination of altitude and year-round mild climate that is so typical for the Andean highlands.

Tropical fruits

I only have this one to share (and it's not a rare fruit at all):



When I ordered coconut water, I didn't expect them to come and drop a coconut with a straw on my table...

And then I discovered that passion fruit is yellow here instead of black (still tastes equally delicious):



Fruits from the highlands

By no means this list is complete, but so far I've tried the following oddities:



Ovos - they are something like a sweet olive. Weird, to say the least.



The chirimoya or custard apple - maybe we had one that was overly ripe, but this thing was revoltingly sweet.



The "pepino dulce" or melon pear tastes like a mixture of melon and cucumber. Odd, and not something I'd recommend.



The "guanabana" or soursop is a delcious fruit that is used for smoothies. It takes quite some time and effort to clean the fruit which contains big seeds, but the flavor of this fruit is amazing.



The "naranjilla" or lulo is family of the tomato (nightshade family), looks like a little orange and tastes like a slightly bitter mashup version of rhubarb and lime. Might sound odd, tastes pretty refreshingly.



"Tuna" is the local prickly pear - and it tastes just a little less sweet than figs.



Tha "babaco" is a large fruit, that is rather sour, and works very well in smoothies.



The "salak" has snake skin, looks like garlic with a pit on the inside, and tastes in between green apples and chestnut.

That's all the oddities I've been sampling so far - and I'll post more when I come across them! Check out my #weridfruitsfromEcuador series on Instagram as well :)

PhD Talk for AcademicTransfer: Cultivating the Art of Writing

on Thursday, December 12, 2013
This post is part of the series PhD Talk for AcademicTransfer: posts written for the Dutch academic career network AcademicTransfer, your go-to resource for all research positions in the Netherlands.

These posts are sponsored by AcademicTransfer, and tailored to those of you interested in pursuing a research position in the Netherlands.

If these posts raise your interest in working as a researcher in the Netherlands, even better - and feel free to fire away any questions you might have on this topic!


Let's talk about the nitty-gritty of academia today. If you are thinking about applying to PhD programs (in the Netherlands, or any other place in the world), you'll need to be ready to roll up your sleeves and type and type until your keyboard comes apart. If you are a seasoned researcher, you know that writing is important, and today's post can help you get your focus clear.

Writing is a skill that I always considered very important. However, when Cal Newport from Study Hacks did the math to determine what makes a successful career in science, and found out that it your number of published papers, and how often they are cited, I realized that, more than anything, writing is what matters in academia.

To understand writing in its different aspects, I've been running the Writers' Lab series over the past year. The writers' lab series contains posts about my experiences writing my dissertation, guest posts from academics and writers from all walks of life, and other topics related to (academic) writing.

But let's say that you are a fledgling graduate student, or an early career researcher wanting to be successful in academia. the previous has shown you that, more than anything, you need to cultivate the art of writing. How do we develop the habit of writing so that we can steadily produce our reports, dissertation chapters and papers?

1. Schedule time

If you start writing a conference paper the night before the deadline, something is wrong with your planning. Research has shown that academic writers who write steadily for a certain amount of time every day, have a larger academic output than those who go for binge-writing.
If you are an (aspiring) PhD student, this means that you should continuously report your work, so that you can pull from that material later on when you need to write a paper, or for when you start writing your dissertation.
If you are an early career researcher, this means that you should try to set aside chunks of writing time, preferably every day, so that you can steadily work on your publications.

2. Have a writing planning

When you schedule time consistently throughout your months and weeks, you also need to know what you want to be writing from week to week and from month to month. Make an overview of the reports, chapters and papers that you need to write, and make a planning for your writing.
PhD students, this means that you have the general overview of which chapters you will be writing when (in which year of your program), and keep space to write background reports and papers that will come up along the road.
Early career researchers, you'll need a planning for writing your journal papers. With all other responsibilities popping up in between, I understood that (when the research is done) 2 to 3 months per paper is a good estimate.

3. Write a lot

Train that writing muscle by writing a lot! It sounds like a no-brainer, but it is so important. By the way, writing e-mails and tweets doesn't count towards your "writing a lot". Develop your writing skills by writing for different audiences. Outside of academia, you can further develop your writing skills through journaling, blogging and writing fiction.

4. Learn from examples

Nothing is a better teacher than an example of a paper that you find particularly clear. Did you notice that some papers seem to take you forever to understand, and that you have to read sentences twice? That can be a sign of poor writing, more than of your poor understanding. On the other hand, do you have a paper that you find yourself nodding along, making little side calculations and sketches? Signs are that this is a clear paper. Analyze papers that you appeal to you. How is the sentence length? How much jargon did the author use? How is the structure of the paper? Learn from this example, and apply these lessons to your own work.

5. Become your own critic

It's time to grow up, folks! Nobody is going to come with a red pen and correct your writing anymore. Your adviser might help you out at the beginning of your PhD, but afterwards poor writing will just be sent to the "reject" pile. Learn to become your own critic. Analyze your sentences, analyze the flow of your paragraphs, the structure of your chapter/paper, and the visual clarity of your figures. Give your work a few weeks of rest, and then return with the sharpest eyes.

6. Figures are part of writing too

When we think about writing, we think about words and sentences. Writing is more than that, however. When we ski through a paper, we typically read the abstract, introduction, conclusions and then glance over the figures. As such, figures are a vital part of our writing. Learn how to draw clear figures (admittedly, I still struggle with this area of my writing). For good references on visual information, check out Edward Tufte's books.

7. Revise profoundly

Revising your work is something that needs to be scheduled too. Don't just make a planning based on the time it takes to write your first draft, but plan time for editing, for letting your work rest, and for discussing it with others. What I learned last year, is that editing my dissertation took twice as much time as writing the first draft. Even though I had major parts of my dissertation in conference papers and reports, revising still took much more time than I could have imagined.
When your writing does not flow, erase an entire paragraph, define the message you want to convey in that paragraph (you can do this by talking out loud: "I want this paragraph do describe such and such based on X and Y"), and then rewrite your entire paragraph. Don't be afraid of wiping out text here and there and starting over new. Instead, know that this is an essential step in moving your writing forwards and towards higher quality.

8. Write with others

As a PhD student, you will mostly be writing with your adviser and committee members. But, if possible, try to broaden your pool of co-authors. You might reach out at conferences to fellow researchers, with whom you might like to work on a publication. When you are exposed to other writers, from different institutions, you will learn from their writing styles, and your own writing will mature as well. Break out of the confinement of your fixed group of co-authors and actively seek cooperation across institutions, countries and disciplines.

Paper in Structural Engineering International

on Tuesday, December 10, 2013


I'm excited to announce my most recent publication, in the IABSE journal of Structural Engineering International.
After the IABSE conference in May of 2013, a number of authors were invited to submit a paper to this special edition on "Assessment, Upgrading, Refurbishment and Conservation of Infrastructures" - and we were among these.

You can access the online version of the paper here.

The abstract of the paper is the following:

Upon assessment of existing reinforced concrete short-span solid slab bridges according to the recently implemented Eurocodes that include more conservative shear capacity provisions and heavier axle loads, a number of these structures were found to be shear-critical. The results from recent experimental research on the shear capacity of slabs indicate that slabs benefit from transverse load distribution. Recommendations for the assessment of solid slab bridges in shear are developed on the basis of these experiments. A load spreading method for the concentrated loads is proposed and the applicability of superposition of loading is studied. The resulting most unfavourable position for the design trucks is provided and implemented in the so-called Dutch "Quick Scan" method (QS-EC2). Cases of existing bridges are studied with the previously used QS-VBC as well as with the QS-EC2 that includes the recommendations. As a result of the assumed transverse load distribution, the shear stress to be considered at the support based on the recommendations becomes smaller.

The keywords of this paper are: EFFECTIVE WIDTH; LIVE LOADS; LOAD DISTRIBUTION; REINFORCED CONCRETE; SHEAR; SLAB BRIDGES.

Four Tips That Will Get You Noticed During a Job Interview

on Sunday, December 8, 2013
Today we are expanding on the topic of finding a job after the PhD. This guest post by Ross Jilling gives you some ideas on how to stand out when you go for a job in the industry.

The economy has made finding a job increasingly difficult, but when you reach the interview stage there are a few steps you can take to increase your chances of landing the position. Being polite, forthcoming, honest, prepared, well-dressed and having extra resumes are all excellent preparation to be made, but if you focus on a few key areas, you’ll stand apart from the pack and increase your chances tremendously. Companies want employees who can communicate well, are personable, and know how to behave in professional settings, and the following will help prove that you are capable of such tasks.

Speak With Authority
The most common mistake people make during interviews is to speak elaborately and meekly. Filler words such as “um” and “like” should be avoided while talking to the interviewer. If necessary, pause while speaking to collect your ideas instead of using filler words. The company wants to see that you can communicate effectively, and as a professional. Verb tense should never be passive, either. A passive tense is typically dull, and many people find it boring. Instead, use active tenses to increase your own energy and raise the interviewer’s interest.

Remaining confident and upbeat can also help, but don’t be disingenuous. An interviewer may think that you come off as fake if you behave with too high-levels of energy. Instead, try to maintain a natural and healthy level of positive energy.

Practice Your Posture
Aside from speech, your posture is the second most important outward trait that others will use to judge you. It’s important not to slouch, recline, or sit awkwardly. It’s also best not to lean against objects while standing and to retain an upright posture. While seated, sit upright, back straight, with your feet planted firmly on the floor, or crossed. Hands should remain at your sides while standing, or in your lap while sitting; never fiddle with objects, play with garments, or fidget since unnecessary distractions may interrupt your thoughts and make conversation awkward.

Eye contact is another important and often-neglected aspect of posture. It may be difficult, but don’t let your eyes wander while speaking to the interviewer. Eye contact creates a human connection, and it also affirms an assertive presence.

Personal Speech
There are common questions asked during nearly every interview. One is surely a variation of “tell me about yourself.” Always prepare for this question by creating a story about your past that has shaped your values, accomplishments, and goals. Make it informative but brief, so the interviewer may ask you questions afterward. Beforehand, do some research about the company and tie the organization’s values into your story as well.

Dress to Succeed
Most interviews will require business dress. For men, that means a button-down shirt and tie, slacks, and dress shoes. For women, it means a business suit, a blouse and skirt, or a dress paired with nice shoes. Appearing at an interview with a slovenly or casual appearance is unacceptable, and most interviewers will discard the interview, no matter how impressive you may be. Choose clothing that fits well and you’ll stand out on your own. Friends or family can help you choose clothing that works best, but remember to dress conservatively and in a way that doesn’t distract from the interview.

It’s important to stand out in a positive way during job interviews. Many interviewers will interview dozens of people, and your chances of getting the job drop dramatically if the interviewer cannot recall much about your time together. Speak clearly, maintain a strong presence, prepare a story that identifies you, dress well, and you’ll stand apart from the crowd.

Project #tweetprop: Feynman and uncertainty

on Thursday, December 5, 2013
The fifth proposition of my dissertation is the following:

I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. (Richard Feynman)

or in Dutch:

Ik kan leven met twijfel, en onzekerheid, en niet weten. Ik denk dat het veel interessanter is te leven met het niet weten dan met antwoorden die misschien verkeerd zijn (Richard Feynman)

This proposition is part of those propositions that are not directly related to the contents of my dissertation, as you might have guessed.

I remember that I was a young child of about 10 years old, and my mother used to read me books before tucking me in for the night. One of the books that she read to me was "Sofie's World" by Jostein Gaarder, a novel about the history of philosophy. Nothing struck me as much as Socrates' "I know that I know nothing".

By the same token, I recall once getting a question at the end of a presentation within our research group. One of my colleagues asked me: "Do you really understand now how shear works in concrete?" I told him that there are two different things here: I do not claim to understand fully how shear in concrete really works - there might be another 100 years of research to fine-tune our findings and keep looking for the ultimate theory on shear. On the other hand, I'm pretty convinced that, by now, I have a good understanding of the topic. At the same time, I remain in awe for the big riddle of shear, which, frankly, still amazes me, while I don't fully understand it.

Along those lines lies what I consider a healthy outlook on the value of our scientific work. We can never know it all. We learn, we grasp some concepts, find a breakthrough, and find a number more questions. All the while, we keep our curiosity to look for more answers. That is the joy and beauty of our work.

So, when I stumbled upon this quote by Richard Feynman, I knew I would borrow it for my propositions. Not only does it fully resonate with how I approach the big questions in life (within my research, and outside of that), but it is also a Feynman quote. And Feynman is the bomb.

I blogged about Feynman earlier, and about his way of breaking down problems into their core elements. One of my favorite books ever is Surely You're Joking, Mr. Feynman! (Adventures of a Curious Character). In this book, Feynman shows us in a very playful way how much science can be. He manages to lift up topics that are as loaded as the development of the atomic bomb into the quest of a young child trying to solve a number of riddles. If anybody can prove us that science is fun, then it is Richard Feynman.

Finally, this quote also resonates with my liking for the zen concept of the beginner's mind. When we keep an attitude of not knowing, of not boasting with confidence on a topic, but carefully exploring the possible answers, without wanting to find a rigid solution - that is when deep work is done, And that is when we approach science both with the respect it deserves as well as with a playful attitude of toying with ideas.

Scheduling class preparation time

on Tuesday, December 3, 2013
As I've started my new job at Universidad San Francisco de Quito, I got 3 courses assigned to teach in the Spring semester. Three new courses to teach means three new courses to prepare - which initially sounded like a ton of work to me.

For reference, the first lecture I ever taught took me roughly 30 hours to prepare. No way I can spend 15 hours per hour of class when I'm teaching 9 hours of class per week...

To figure out how much time I should schedule, and get a realistic idea of what to expect next semester, I turned to the Biggest Oracle of our World aka the internet.

First of all, I stumbled upon this great resource from University of Chicago on preparing to teach. This document takes you step-by-step through the process of preparing a new course: from the moment you put your syllabus together to the actual delivery of your class.

Then, I found that the American Faculty Association discusses the topic of class preparation time very directly. They give 2 to 4 hours of preparation time as a rule of thumb. My planning is happy with getting a real estimate of the required time.

I also learned (not really to my surprise) that, as with everything, there is a law of diminishing returns for class preparation time. The more time you plan to spend preparing, the more time it will take up. We know that from PhD research too. The guideline from this resource is "Two hours for new lectures and half an hour for lectures you've given before is a good guideline". The authors of the article suggest a "mean and lean" approach to preparing for your class - and I am planning to follow this approach.

Finally, I turned to Twitter to get advice from more experienced lecturers. Many times, 4 hours of preparation for a new class is coming up. The Storify of this discussion is here at the bottom of this post.

In conclusion: I'm scheduling 4 hours of preparation per class. As suggested in the "mean and lean" approach, I am subdividing that into the following activities:
45 minutes to read the class material
45 minutes to distill all important information
15 minutes to outline the class hour
45 minutes to construct the argument around the "what if" question
45 minutes to prepare an example and possible homework
45 minutes right before class to make some slides with figures that are complicated to draw on the blackboard, or pictures from practice, and to revise all material.
