Student Success Coach, City Year Greater Boston. Brown Biology alum; Fulbright Scholar in Taiwan; matriculating medical student; contestant on Jeopardy!
 
Andy Luo was an undergraduate researcher in the Kartzinel Lab for three years and a core member of our Italian wall lizard project team. Andy’s research focused on the physiological and behavioral mechanisms that allow a Mediterranean lizard to persist through the frigid Boston winters—work that culminated in an Honors thesis and a first-authored manuscript (in review at Herpetology Notes). After graduating, Andy pursued a path that bridges science, education, and service: he spent 11 months in rural Chiayi County, Taiwan as a Fulbright English Teaching Assistant. Before starting medical school in 2026, Andy has served as a Student Success Coach with City Year Greater Boston to support fifth graders in an under-resourced public school.

Dr. Bethan Littleford‑Colquhoun was a postdoctoral researcher in the Kartzinel Lab (2020–2025) and a key driver of our NSF-funded Yellowstone wildlife research program in collaboration with the National Park Service. Her work uses dietary DNA metabarcoding and microbiome ecology to understand how wild herbivores respond to seasonal change and migration. She is now a faculty member in Microbiomics at the University of Bath.
