About
I am a Ph.D. candidate in the Department of Biostatistics and Bioinformatics at Emory University, working with Prof. Benjamin B. Risk.
Prior to Emory, I received my BS degree in Statistics from Nankai University, and an MS degree from University of Wisconsin-Madison.
My research interests center around developing statistical methods and computational tools to analyze complex biomedical (neuroimaging/genetics) data.
