About Me
Currently I am a Principal Biostatistician at PPD, Austin TX. I finished my Ph.D. (2014 Aug) in Statistics at University of Florida. I am also working as a research assistant for my advisor Dr. Mike Daniels at University of Texas at Austin. My research topic includes quantile regression in frequentist and Bayesian framework and methodology for (incomplete) longitudinal data. Previously, I worked as an intern for Educational Testing Service (ETS) supervised under Dr. Yi-Hsuan Lee and Dr. Alina von Davier. Before coming to US, I had a B.S. in Mathematics at Fudan University, Shanghai, China.
