I am currently working as a post-doctoral researcher with Prof. Richard A. Davis at the Department of Statistics of Columbia University. I am focusing on two projects motivated by a massive snapshot of the Google+ social network. One project is on methodology development for analysis of heavy-tailed data when a portion of the extreme values are unavailable. The other project focuses on importance sampling on directed networks, in which the network's topological structure is utilized to increase the probability of sampling nodes with desired but rare properties.
Prior to my post-doc work, I studied at the Department of Statistics of Columbia University and graduated from the Ph.D. program in May 2015. I was working with Prof. Daniel Rabinowitz and my dissertation work was on developing efficient allocation strategies in lung transplantation. My research interests lie in methodology developments of extreme value theory and stochastic control and their applications to healthcare and networks. I have also done works related to change-point detection and dimensionality reduction in high-dimensional fMRI data and have a growing interest in these areas.
