Peer Concentration Advisors (PCA) Program

PCAs serve as peer advisors for pre-concentrators (and current concentrators), providing a valuable perspective and helping students to discover additional resources and opportunities.

If you would like to be matched to a PCA, you can do one of the following:

  1. Reach out by email to a PCA with similar academic, career, or extracurricular interests by exploring their bios below. 
  2. Get paired with a PCA by filling out the Find my PCA Google Form. While we recognize some students might know exactly what they are looking for, we are happy to help pair you. 

If you would like to contact our PCA Co-Captains directly, please feel free to reach out to Veronica Santana ( or Jackson Walker (

If you are interested in becoming a PCA, contact


Veronica Santana (Co-Captain)


Hi everyone! My name is Veronica Santana and I am excited to be a senior in Applied Math. I have a somewhat unusual focus field of Sociology so please reach out with any questions about quantitative social science that you might have! I have worked and am working with professors on campus using my quantitative and qualitative skills in research about police department use of force and student paid work as well as having interned with the ACLU researching educational inequity. Outside of AM I spend a lot of my time on campus working as a math course assistant, being a peer counselor, working on the First-Year Urban Program and petting all of the dogs I see. Some other fun facts, I am a proud Dunster Moose, I’m from Southern California (ask me about why it’s the greatest place on earth), and I am also a proud member of the Mexican-American and LGBTQ+ communities. Please don’t hesitate to reach out, I’m passionate about making sure that everyone knows applied math can be a home for them! Studying STEM as part of an underrepresented community can definitely be hard but please feel that you can reach out for support, I’m always happy to talk about anything :)


Jackson Walker (Co-Captain)


Hey y'all! My name is Jackson Walker and I'm a senior in Dunster House (obviously studying applied math) and I'm super excited to be an AM PCA this year. I'm originally from the bustling metropolis of Wilton, Connecticut (a small town in Southwestern CT) but am technically now from Southern Florida. Outside of the classroom, I work on the steering committee for FOP and serve as a PAF! My application field in AM is biological sciences, and in addition to my concentration I am also a premed student. Balancing AM and premed requirements may sound challenging, but it's definitely a great option for people interested in the more quantitative side of medicine. Since my sophomore year, I've worked on computational biology research with Sean Eddy on the application of neural networks to protein homology (or protein relation)! As a bit more about me, I identify as a low-income student who is also Black, gay and latinx (Domincan + Colombian)! I know that studying AM as a member of an underrepresented group in STEM can be really intimidating so please reach out if you feel that you'd be out of place studying AM. And generally, I love people and advising, so please feel that you can reach out about anything AM adjacent :)

Hi! My name is Prasidh Chhabria, and I'm a junior in Eliot House studying Applied Math; I've lived in both the Bay Area in California and Mumbai, India. With my area of application in Biological Sciences, I'm interested in the application of quantitative and computational methods to tackle biological problems, across academia and industry. I'm particularly drawn to problems in statistical inference, machine learning, and modeling, which I've explored through coursework and research (exploring RNA circularization at Novartis and studying quantitative health indicators at the Harvard School of Public Health). Outside of AM, I enjoy exploring Boston and lead a dance group on campus. The AM community has been a source of support, inspiration, and friendship for me, and I look forward to meeting all of you - please reach out if you'd like to talk about AM+bio/chem or anything in general!


Itay Dvir


Hello! My name is Itay Dvir and I am a junior studying Applied Math with a focus field in Economics and I am also doing a minor in Psychology! I love this combination as I feel as though I am getting a much more holistic view of the field of Economics, by diving deeper into the deeper technical skills that are used by Economics all over the world while also understanding the aspects of human behavior that drive our decisions! On-campus I enjoy my work as a Peer-Advising Fellow for First Years, playing club volleyball, being a course assistant for Economics, participating in Consulting with TAMID Group, and being a part of the best house community on campus in Currier!
