I'm a fourth-year graduate student at UCLA, working in applied math with Andrea Bertozzi. I graduated with a B.S. in Math from Zhejiang University.
I'm currently modeling spatio-temporal data from human activities such as violent crimes and social network via multivariate self-exicting point process. This work was supported by a National Institute of Justice Graduate Research Fellowship (GRF-STEM). I also working on time series analysis in medical imaging and seismology using machine learning. Some of this work has been in conjunction with Los Alamos National Laboratory.
