Co-Chairs of Professional Development

Alessandra Bryan
Hi, I’m Alessandra and I am a proud member of the 2028 class. I'm so excited to be a Co-Chair of Professional Development. I’m from Winston-Salem, North Carolina. I graduated from Hobart and William Smith Colleges in upstate NY where I was a member of the Women’s Soccer Team. After college, I moved to Nantucket, MA and worked as a live-in nanny for two years. Following that, I moved to Quechee, VT and began working as a research coordinator in the Department of Anesthesiology at DHMC. Living in the Upper Valley for two years before starting at Geisel was the best experience yet - and now I consider myself a native! In my free time, I love to play soccer, ski, and spend time with my family and friends.

Corbin Dameron
My name is Corbin Dameron and I am so excited to be joining Helen as co-Chair of Academics. I am from Charlottesville, Virginia and attended Middlebury College where I studied neuroscience. Before coming to Geisel, I moved a lot, climbed some mountains, worked as a scribe in medical oncology, volunteered at needle exchanges, and did a post-bacc and some research in addition to various very odd jobs. I have been an MEC rep for the past two years, president of PrideMD for the past year, Schweitzer Fellow with Healing Harvest, and co-coordinator of Big/Little sib pairings. I am passionate about medical education and hope to one day teach medical students! I love playing ultimate frisbee with my new ACL (shout out to Dr. Ames), swimming in lakes, biking, and reading.

Prior to medical school, I worked at a start-up in San Francisco, taught cello lessons, and coached water polo. During my time at Geisel, I have been involved with medical education work because I see it as a way of supporting my peers. This year, I look forward to amplifying student ideas for medical education reform.

Co-Chairs of Diversity and Inclusion

Eric Wang
Hi everyone! My name is Eric Wang, and I have the utmost pleasure of serving as one of your Co-Chairs of Diversity and Inclusion for the 2025-2026 school year. I grew up in Westchester County, NY before moving to NYC, where I attended the College of Arts and Science (CAS) at New York University, having graduated in 2021 with a BA in Biochemistry and a Minor in Mathematics. After graduating, I pursued a MS in Human Nutrition at Columbia University, receiving my degree in 2022, and worked as an education assistant and clinical research coordinator at Columbia and Mount Sinai Morningside, respectively. During that same timeframe, I also helped found what would eventually become the 501(c)(3) non-profit organization, Cultural Heritage and Identity through Food And Nutrition (CHIFAN), which focuses on delivering culturally relevant nutrition education to NYC youth. Currently, I am an MS3 with a specialty interest in dermatology. Outside my academic work, my hobbies include dance, fashion, skincare, K-pop, and watching anime. Most importantly, however, I am a major foodie!

Hi everyone! My name is Annie Cao and I’m originally from the great state of New Jersey. I went to Johns Hopkins University for undergrad, majoring in Molecular & Cellular Biology as well as Public Health. After graduating in 2022, I worked as a lab manager for the Carnegie Institute of Science and as an EMT in Baltimore County. Then, I attended the University of Oxford in the UK where I obtained an MSc in Medical Anthropology. In my spare time, I love to create art and bake Asian-inspired sweets. I also once raised 3 baby ducklings in my shower, who later imprinted on me and followed me around everywhere (shoutout to Poe, Piplup, and Cricket).
