Research for the First Time
by Kevin Vargas
Before attending college, I
was never really sure what I wanted to do after graduation. In fact, I’m still
not completely sure, and I’m already halfway finished with college. When I applied
to college, I applied as an economics and sociology double major. Therefore I
never considered doing scientific research or anything science-related. However,
once I started college and decided to take courses in biology, chemistry, and
math, I considered becoming involved with research to further my understanding
of the scientific method and how new discoveries take place. There was one
problem though: I didn’t know where to
begin.
Luckily, I received an email
from my cultural center encouraging interested students to apply to the
Science, Technology, and Research Scholars (STARS) Program through the Yale
College Dean’s Office. The program was created and designed to support and
provide resources to underrepresented students in science, technology,
engineering, and mathematics (STEM) fields, such as women, minorities, and economically
underprivileged students. Students accepted into the STARS Summer Research
Program receive a summer stipend, on-campus housing, and a class on how to
create a research paper and presentation. I knew that I needed to take
advantage of this opportunity so I applied and was fortunate enough to be accepted
into the program. Next, I needed to find a principal investigator (PI) and
mentor who would allow me to join their lab for the summer and introduce me to
research work. I contacted Professor Jay Humphrey, a leading researcher in the
field of vascular mechanics and tissue engineering, who allowed me to work in
his lab. I was under the mentorship of a Ph.D candidate, David, and joined a
group of graduate students working on various projects in the lab.
My work primarily focused on
the relationship between mechanical strain and collagen production in
adventitial fibroblasts. Adventitial fibroblasts are cells located in the
outermost layer of connective tissue covering things like organs or vessels.
They synthesize proteins necessary for healing cuts and other injuries and
produce collagen for support in connective tissue. Prior research has shown
that collagen determines large artery stiffness, which then contributes to cardiovascular
disease, one of the leading causes of death in the world. Therefore, a greater
understanding of the role adventitial fibroblasts play alongside other effects
of stimuli on collagen production will result in a greater ability to prevent
and treat cardiovascular related diseases.
During that summer, David and
I collected cells from a mouse aorta in the lab, grew those cells, and placed
them into a bioreactor that simulated blood pressure flow in the human body. We
had to be sure that we had isolated the correct cells and that they survived
the bioreactor, otherwise our research would not be useful. The research we
conducted was important in helping to understand the role arterial wall stiffness
plays in vascular disease.
By the end of the program, I
had written a final paper detailing our research and its importance. I had also
created a presentation during the summer class and was actually able to present
it at a symposium filled with other scientists. It was also an awesome
experience to understand how scientific research worked, especially since I had
never worked in a lab before. It was also nice learning how to write a
scientific paper as well as create and actually present a presentation in front
of other researchers. I feel like I am a better writer and public speaker as a
result. With this exposure to scientific research in adventitial fibroblasts,
I’ve decided to declare my major as Biomedical Engineering. Therefore, I will
definitely use this experience as I go into my final two years of college and
possibly even after graduation.
