I want to be a beach bum

By Dustin Britton

What do you want to do after you graduate?

“I want to be a beach bum.”

Although that wasn’t my long-term goal, it was still my best plan after completing both undergraduate and master’s degrees.

I owe much of my current research drive to an unexpected 12 weeks that evolved my perspective on pursuing scientific research. Prior, my classes taught me thermodynamics, separations, and transport theory. My notebooks were filled with long differential equations and little understanding of the practical relevance of my newfound knowledge. My internship experiences consisted of trudging through pungent, dirty plants with steel toed boots and a hard hat to take mundane measurements and process check-ups: ‘everything is running well as usual.’ It is putting it mildly to say that I was disillusioned with the postgraduate job prospects that Chemical Engineering beheld. I had expected to ‘engineer chemicals’ for an albeit corny, ‘better world.’

Thus, I entered a 12 month Master’s program in Chemical Engineering primarily to postpone my job search and to extend the enjoyment of college. My program involved completion of graduate coursework in the first two semesters followed by a research project as a Particle Technology Intern for the Chemours Company. Because I had never set foot in the lab outside of my undergraduate core classes, I had no concept of what scientific research entailed. I learned that my research group at the Chemours Company would include one principal scientist (or Principal Investigator, P.I.) and myself. The company was based out of a research facility in Wilmington, Delaware. I was not excited.

My job consisted of carefully preparing various powder materials into stainless steel holders for various rheology devices. I was also tasked to read (embarrassingly with not much enthusiasm or effort) about bulk solids flow and rheology theory. After about six weeks I was able to collect my first real set of data. Still, I was not excited.

Shortly after, my P.I. showed me how my readings on theory were related to the results I had tediously collected. I was taught to search and analyze trends to elucidate novel relationships. I was shown how to present my data and defend my thoughts. I was encouraged to derive my own ideas and improve experimental designs. I was given my first opportunity to relate my academic experience to industrial application. This was fascinating and exciting.

The process then repeated itself, but this time, I was vested and knew what the end bore. I fell in love with the process of using fundamental knowledge to extrapolate an idea and ultimately create a unique discovery. This deeply changed my idea of how I could contribute to the world with my education and skill set. I owe a lot to my PI and the independence and challenges he presented me with as a part of my first research experience. Shortly after, I applied to a Ph.D. program to continue the pursuit of scientific discovery.

I feel incredibly lucky that my career has found me rather than the opposite. My journey to pursuing a Ph.D. is uncommon among my peers. While it seems that many who pursue a Ph.D. have an earlier semblance of their scientific goals, I remind myself that my journey also conveys my passion for scientific research and demonstrates a love for discovery and engineering a better world.

If you were to ask me now what I want to do after I graduate, I will  say:

“I want to be a beach bum…. But only for a little bit.”

“ I want to head back to the lab.”

The New Vanguard: First-Generation Students

 By Stanley Chu

Being the first to accomplish something, especially in STEM, is an achievement. Pioneers are lauded for their contributions to the field and remembered for their triumphs. But what’s  often forgotten is the loneliness, insecurity, and oftentimes guilt associated with that journey. First-generation students, those that are the first in their family to attend college, face a similar struggle. While it is difficult to pin an exact definition of who is included in this group, what can be said about first-generation (first-gen) students is that they often “lack the critical cultural capital necessary for college success because their parents did not attend college.”1 This “cultural capital” refers to the intangibles that contribute to student success in a college setting.

As a first-gen student, perhaps one of the toughest challenges I’ve had to face in pursuing higher education was my relationship with my family. My family immigrated to America from Hong Kong in the 80’s. As is true for many immigrant families, the move was inspired with the hopes of having more opportunities in America. It’s the dream of many immigrant parents to watch their kids pursue higher education. While I was able to earn my PhD in STEM, I wasn’t able to share the entirety of this journey with my mother. For one, I simply do not have the Chinese vocabulary to describe Chemical Engineering to my mother. I lack the language to describe my research and to accurately portray the rigors of academia. While my family has been approving in my academic pursuits, they were unable to act as an effective support system during my undergraduate and graduate years when it came to academic affairs.

For many of my peers who are also first-gen, they too experience a lack of family support. It is well documented that students in higher education experience more issues with mental health. A Nature report has suggested that there is a mental health crisis amongst graduate students, with graduate students six times more likely to experience anxiety and depression compared to the general population.2 What is a mentally challenging time for all graduate students is even more so for first-gen students who often find that their family does not or will not understand their mental health issues. In my final months of graduate school, I began therapy sessions and even sought medical help to cope with the pressures of academia. When I shared my decision to seek treatment with my family, I was met with pushback. I was told I wasn’t “depressed”, but “just lazy”. I was told that the decision to take prescription medicine should’ve been a family decision. Many first-gen students come from cultures that do not view mental health as important as physical health. For this reason, I am very vocal about my own experiences and about mental health education.

First-gen students also lack family mentors, specifically in navigating the culture of academia. This may manifest in lacking guidance in selecting what fields to major in, not having safe and effective outlets for venting frustrations, and a general disconnect with family members. Family members who have never gone to college can’t appreciate the unique pressures that one faces in college and graduate school. Family members may even discredit their issues and invalidate their experiences as a first-gen student, further distancing first-gen students from their families.

My advisor, labmates, and I celebrate after I successfully defend my PhD. Graduate school is an academic and emotional challenge. Finding your chosen family that can empathize with your situation is crucial in maintaining your mental health.

First-gen students also receive less help in the college setting and have less resources. Many first-gen students come from low- to middle-income families. Thus, many first-gen students often work in order to support themselves through college. This also means that many first-gen students cannot afford to live on campus, thereby creating a different (and perhaps more isolating) college experience compared to non-first-gen students. While it is great to see more resources available for increasing diversity in STEM, first-generation students are not considered an underrepresented minority, thus there are not as many  opportunities for financial support. And, I believe the biggest disadvantage for first-gen students is that they have to build their professional network from scratch. Many non-first-gen students enter college able to rely on the professional network of their parents. For example, many professional opportunities, such as internships or co-ops, come from family friends.

My intentions with this blogpost are twofold. Foremost, I want to document a small portion of my experiences to spark dialogue in the greater community. It is my hope that by bringing the community together through conversation, first-gen students can find their peers and realize that they are not fighting this battle alone. I have found Twitter to be an extremely powerful platform for connecting with students all over the world. In terms of connecting with first-gen students, @firstgendocs serves as an excellent resource for finding other first-gen students and they also host cyber-workshops and events. Secondly, by bringing more attention to this issue, I hope that academic institutions recognize the legitimacy of the challenges faced by first-gen students and provide additional resources to support first-gen success.  Already, there are several organizations investigating the various statistics 1 about first-gen students as well as serving as a database for financial resources 3 for first-gen students.

The word “trailblazer”, although trite, seems appropriate for first-generation academics. To me, it invokes imagery of audacious explorers, torch and machete in hand, lost in the thick foliage and shrubbery of the jungle. There is no set path to follow and the unknown can often be crippling. But there’s beauty and power in this. To move forward and survive, they must be comfortable with being uncomfortable, and use their tools to hack away at the vinery and burn away obstacles. Go forth, make your own rules, and don’t forget to reach back to give others the same chances that helped you succeed.

I would love to connect with you and follow your journey in STEM!

My Interest in Protein Engineering Research

By Xiaole Wang

In one of my undergraduate biochemistry labs, I was introduced to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). This is a process by which proteins are separated based on size from a protein sample with various kinds of protein. Running these experiments sparked my interest in biology research. After this experience, I joined a lab where I studied a food related polypeptide derived from naked oats. I was surprised to find that this kind of polypeptide is able to prevent blood sugar spikes after meals. Because I desired to understand proteins with greater nuance, I followed up my undergraduate study by enrolling in the NYU Tandon School of Engineering, majoring in biotechnology. In addition to my studies in the Engineering department, Dr. Montclare has given me the opportunity to volunteer in her lab where I have broadened my experience in protein related research, especially in protein engineering.

I am amazed that proteins, composed of only 20 different building blocks, bear function in almost all of life’s activities. They play an essential role in daily exercise, cellular growth, metabolism, immunity, gene inheritance, and evolution of species. From microscopic creatures to dinosaurs with legs the size of the Parthenon’s columns, life cannot exist without proteins. However, there are many proteins that remain unknown in their function. Scientists continue to make steps in uncovering the mystery of nature by identifying new proteins. With the advances in gene manipulation, it is now possible to produce artificial “engineered” proteins. These engineered proteins can be developed to address issues in human health care. For instance, the creation of Cetuximab, a drug used for cancer treatment, is achieved through protein engineering. Also, protein engineering made it possible to artificially synthesize insulin (Goeddel et al., 1979).

Currently, I am working on a research project with protein based hydrogels, a kind of biomaterial that absorbs water and binds drug molecules. Hydrogels are thus capable of retaining moisture or delivering drugs for wound healing. By means of protein engineering, I am able to let E. coli (a very common bacteria existing in our gut) produce protein needed for hydrogel. Then, I let the protein chemically cross-link with each other to form cross-linked molecules that are able to shape hydrogel. With necessary handling of the gel, its ability of drug delivery is then tested on a mouse with wound. It turns out that the hydrogel works well!

A master’s level is not enough for providing me with necessary knowledge and skills to go deeply into this field. I am committed to pursuing a PhD to continue my interest in protein engineering.

Breaking the Gender Stereotypes in STEM

By Jordyn Pierre-Raphael

Most little girls like to play dress-up with their dolls, but when I was younger I always treated my dolls as “patients,” who needed my help with a fever or a stuffy nose. I remember that I would wear a lab coat and use my plastic stethoscope to listen to my patients’ heartbeats. At this young age is when I first decided I wanted to become a doctor for the simple reason that I found helping people to be rewarding. In retrospect, I acknowledge my naivety because many occupations involve helping people in one way or another, but my motivations have certainly changed as I have matured and become more interested in the field of science.

In high school, I have developed a passion for science because it challenges me while simultaneously feeds my sense of curiosity. I have taken almost all of the accelerated science courses offered at my school, and my favorite of the many I have taken so far would definitely have to be Experimental Chemistry. It is a semester laboratory intensive course where I was exposed to some of the challenges that must be addressed in moving a chemical reaction from the page to the plant. This course taught me about advanced laboratory techniques for synthesis, purification, and analysis of compounds, including thin layer chromatography, gas chromatography, and UV-Vis spectroscopy, and the hands-on aspect of the course reminded me of my work in the Montclare Lab. I think the most important concept that I learned from the course is how important it is to approach problem-solving with a creative and collaborative mindset, and I have carried these skills with me as I work in the lab because of how pertinent they are.

I feel as though it is important to note that in my Experimental Chemistry class there were twelve students, and I was one of only three girls. This has been a recurring experience for me because almost all of my science classes are male-dominated, which caused me to become used to being interrupted or talked over more times than I could count by my male peers.

After talking with some of my female peers, I realized that we shared similar experiences in our science classes. Many talked about how they avoided participating in class because they feared judgment from their male peers, and this was something I had experienced but worked to overcome because it was stifling my learning experience. This is why I restarted the Women in STEM club at my school because I wanted the girls in my community to have a space where they could feel encouraged to study and then enter STEM fields as well as gain exposure to STEM-related opportunities at school. Over the past year of leading Women in STEM, it has been amazing to see other girls in my community be inspired to join the STEM field by enrolling in my school’s science courses, such as the Independent Science Research program which allowed me to work in the Montclare Lab. The Independent Science Research Program is a three year course at my school in which select high school students are able to pursue a science field of their interest, work in a professional research lab, and participate in science competitions during their junior and senior year. It is more of an experience than a class, in fact, as you are able to gain extensive public speaking practice, gain experience reading professional journal articles, and become knowledgeable about a field that you are passionate about. Few high school students are able to say that they worked in a research lab and gained research experience, and I can definitely say that I cherish the opportunity I have been given because I have been able to work with college graduate and undergraduate students and postdocs who are all so passionate about a field of research. My experience at the Montclare Lab has certainly inspired me to pursue scientific research when I am a college student!

What I’ve Learned to Live My Best Life as a Maker in the Lab

By Shengbo Guo

Edited by Eliza Neidhart

Having graduated two months ago, I am situated at a point of transition. I cannot be counted as a student technically, yet I continue to work in the lab and interact with the world just as any other student. We students stay up late, wake up early, and have fully committed our lives to be intertwined with work. My research in protein engineering requires me to return to the lab at strange times.

 

What is a protein? We know proteins are found in the meat and beans that we eat. This is because they are the building blocks of animals and plants! Inside of animals and plants, they act like tiny workers in a factory, performing tasks for the larger organism. Some proteins chop our food into tiny digestible bits (proteins can chop proteins! woa!) while others do quality control to ensure our bodies produce safe and quality materials.

The protein I am working on is Phosphotriesterase, aka PTE. I think of it as a tiny machine that convertsF toxic pesticides and military grade nerve agents into nontoxic substances

Now, back to my daily life. To give you a better idea of my research I’d like to describe my research processes as if it were a recipe for finicky cookies.

EXPERIMENTAL FLOWER COOKIES

Ingredients:

  • 3 Tablespoons of yeast

  • 6 cups flour

  • 1 cup 98-degree F water

Directions:

  1. First, mix yeast, flour, and water. Allow to rise for 24 hours.  *Every 3 hours additional warm water must be added.

  2. Next, knead the dough for a full 10 hours.

  3. Refrigerate overnight.

  4. Form flower shapes in the morning. *Unfortunately, this step is very very slow. The flowers tend to crack. They do not look as pretty as you’d imagined. There are no photos showing you what they should look like because this has never been done before.

  5. Finally, bake flower cookies for 2 days in a solar powered oven. *For some reason this is the only way they have a chance of remaining intact. Usually, the pastry flowers do not turn out as expected and need to be made again.

Warning: The recipe means loss of sleep on day 1, tired hands on day 2, and frustration on day 3. This recipe may need to be attempted (with adaptations) 10 times for an acceptable result. Yet, success is delicious.

While my lifestyle is exhausting due to these long and intensive recipes, I have developed techniques to live my best life.

The first way I stay happy is through interactions with good people. I work most closely with Andrew Olsen, who is not only a good labmate, but also an excellent mentor. I remember the first day I met him, the day of my interview for the Montclare lab. He found me nervous, hovering in front of the lab building. Amazingly, his affable nature was able to calm me somewhat. I still remember the interview questions he asked me as well as the simultaneous nervous churning of my stomach. Anyway, I really enjoy life here with Andrew and my other labmates.

In the lab, recording and summarizing has made my life better. When I begin each experiment, I make detailed documentation of my process; not only the simple procedure which I can get from protocol. More importantly, I leave personal notes and reminders which can only come from practical experience. Returning to the baking metaphor, no cookbook would tell you that adding  dry flour to the cookies before baking makes them crispier. However, hands on experience and notetaking would give a baker this insight. After recording, I have learned that summarizing plays an essential role in conceptually understanding research work. I am currently summarizing the lab’s entire workflow. Through this work, I have gained a fundamental understanding of our research which allows me to complete my portion of the workflow more successfully.

Regular exercise is helpful not only to my personal life, but also for my work. I play table tennis in the basement of my lab building in the evenings. It is relaxing and allows me to sleep more soundly. The following day I am energized and more efficient in the lab. Additionally, I have made friends while playing. Being from China with english as my second language, I enjoy the opportunity to continue practicing during these social times. My improved English skills have been helpful to my daily life and communication in the lab. In addition to pingpong, I play soccer on the weekends for a cardio workout.  Working out along with note taking and summarizing help me to live a reduced stress life even with the long work hours that protein engineering requires.
