Sylvia obtained her undergraduate degree from the University of Oregon, where she worked under the mentorship of Caitlin Kowalski in the Barber lab. She is excited to continue supporting Caitlin at Dartmouth, studying how intermicrobial interactions are shaped by lipid-rich environments. Outside of lab, Sylvia can be found knitting, painting, and exploring the reaches of the Upper Valley.

Hannah Kim

Dartmouth Geisel Medical Student

Hannah is an M1 at Geisel School of Medicine. She earned her undergraduate degree in English with a minor in Korean at UCLA, and completed an M.S. in Narrative Medicine at Columbia University. She is passionate about patient advocacy and the personal meaning patients ascribe to illness, drawing her to pediatric dermatology as a visual, longitudinal field. Her scientific interests center on interactions between environmental modulators and the immune system, particularly how the skin microbiome shapes inflammation, immune surveillance, and progression of dermatologic conditions. Outside of medicine, Hannah enjoys walking, bouldering, writing, and experimenting with new recipes.
