MD/Ph.D. Reps

Abby Marshall

My name is Abby Marshall and I’m a fifth-year student in the MD-PhD program. I’ve completed my first two years (or Phase I) of classes at Geisel and am now working towards my PhD in Dr. Aaron McKenna’s lab! My research focuses on engineering CRISPR-Cas9 systems to enable lineage tracing in patient-derived xenograft models of cancer, particularly glioblastoma. In my free time I enjoy running, hiking with my dogs, and cross-country skiing. I’m looking forward to contributing the MD-PhD perspective to Student Government and helping to keep our unique cohort of students connected to the broader Geisel community!


Pauline Mochama

Hi there! I'm excited to serve as one of the MD/PhD reps as well as a community service rep for my class. I’m originally from Nairobi, Kenya but moved to Minnesota as a teen. I have a bachelor’s degree in Biology and a master’s in Microbiology. I previously worked in various academic research positions before joining medical school. In my free time, I enjoy cooking, hosting, gardening (indoors and outdoors), watching comedy shows and vlogs, and journaling.


Thomas Skipper

I was born in Oxford, England before emigrating to Norwalk, Connecticut as a child. I went to Brown University for my undergraduate degree and studied Biomedical Engineering. After graduating, I worked on preclinical validation of new cancer targets from genome-scale CRISPR/Cas9 screens at the Broad Institute. By pursuing an MD/PhD at Dartmouth, I hope to become a physician-scientist and apply novel cancer biology from the lab to precision medicine in the clinic. In my free time, I enjoy reading, discovering new music, and following premier league soccer (football). I am loving my time at Dartmouth so far—from hiking in the fall, skiing in the winter, to mountain biking in the summer, every season has something new to offer and to get me outside!



Jack F. Donaghue

I'm originally from Hershey Pennsylvania with the smell of chocolate in the air! It is a small town with a tight knit community similar to the Upper Valley. I went on to play Division 1 lacrosse at Colgate University where I studied neuroscience and how beliefs about intelligence and skills influence our ability to learn. After undergrad I moved to NYC where I worked at in a lab at NYU researching novel immunotherapies for lung cancer. I was fortunate to work with the thoracic surgeons at NYU during my time there and developed an interest in cardiothoracic surgery. Since coming to Geisel I've further explored CT surgery and become interested in adult cardiac and congenital cardiac surgery. I've recently joined the MD-MBA class of 2026 and I'm excited to represent this crew to student government.

Liam Synan

Liam is a 2024 MD/MBA candidate, and interested in healthcare economics and medical education. He's from Bedford, NH.

AAMC Organization of Student Representatives (OSRs) 

Amal Cheema

Hello! I’m Amal and I’m a M4. I had the privilege of being elected for a second time as the National Delegate for Policy & Advocacy, as part of the AAMC OSR Administrative Board. I firmly believe that healthcare challenges are best approached with compassionate approaches — that alleviate suffering, mitigate inequity, elevate marginalized voices, and balance complexity with scalability. I carry this mission throughout all my work, and as National Delegate, hope to empower medical students in their ability to engage with issues facing academic medicine on a national level. With Geisel’s three other OSRs, I look forward to encouraging the bidirectional sharing of innovations happening in medical education at Geisel and across the nation.
