I'm a fourth-year graduate student in mathematics at Harvard, and my main area of research is low-dimensional topology. My Ph.D. advisor is Peter Kronheimer.

Peter Kronheimer and I are organizing the Gauge Theory and Topology Seminar this semester.

Personal

My partner Teresa Tang draws dugongs and has published a sticker pack for iMessage!
