About

I am a sixth year PhD student in the department of Electrical Engineering and Computer Science at UC Berkeley, advised by Yun S. Song and Nir Yosef. Broadly speaking, I work on mathematical and computational biology. More specifically, I am interested in statistical phylogenetics and its intersection with single-cell biology. Two key areas I am interested in are protein evolution and cancer evolution. Methodologically, my work is themed around finding clever tradeoffs between computational efficiency and statistical efficiency (or accuracy) when analyzing large biological datasets. Indeed, many biological datasets have reached a point where they are too large to analyze with conventional methods, and more clever, scalable methods are needed. Here, by ‘clever’ we mean that the increased scalability comes at a small cost of accuracy. The best example of this is my work on CherryML for rate matrix estimation, where we developed a method that is thousands of times faster than the state-of-the-art, while being only two times less statistically efficient (rather than thousands, which would be trivially achievable by subsampling the dataset).
