I am a research scientist at Facebook working on experimentation methodology and machine learning for News Feed. Before that, I was a postdoctoral researcher at Stanford University and HHMI working with Jonathan Pritchard
on statistical models and inference algorithms for genomics applications.
Prior to that, I was a JSPS postdoctoral fellow
graciously hosted by Hideki Innan
at the Graduate University for Advanced Studies
in Hayama, Japan, and a Simons-Berkeley research fellow in the semester-long program on Evolutionary Biology and the Theory of Computing
at the Simons Institute for the Theory of Computing.
I received my PhD in Computer Science at the University of California, Berkeley where I worked with Yun S. Song
on mathematical genetics.
Before that, I received my B.S. and M.Eng. degrees in Computer Science from Cornell University, and an M.A. in Statistics from Berkeley.
I also spent two wonderful years in boarding school
while studying in the 11th
grades in Raffles Junior College
I develop and apply techniques from statistics, computer science, and applied mathematics to problems in experimentation methodology and ML model interpretability. I am particularly interested in experiment design for measuring network effects.
In my graduate and postdoctoral research, I have built statistical models and inference methods that utilize large-scale genomic datasets to address fundamental scientific questions such as the genetic basis of disease, human demographic history, and forensic genetics, among others. My work has involved developing analysis methods using techniques from statistics, applied mathematics, and computer science, and developing software that can be applied to genomic datasets for scientific discovery.
