I am a PhD student in Computer Science at Princeton University. I am very fortunate to be advised by Ben Raphael and to be supported by an NSF Graduate Research Fellowship.

I am broadly interested in developing statistical models and algorithms to address problems in biology (occasionally machine learning too). My current research interests include spatial transcriptomics, biological network analysis, and epistasis.

Personal

Outside of research, I spend a fair amount of time bouldering — check out my climbing Instagram for some videos!

I also enjoy biking around Princeton, struggling on crosswords, puzzles, and bad puns.
