New seminar class in Fall 2018 and Spring 2019: Topics in Deep Learning (STAT-991), surveying advanced topics in deep learning research based on student presentations. See here for the syllabus and for the lecture notes.

Education (cv):

  • PhD in Statistics, Stanford University, 2017.  Advisor: David Donoho
  • BA in Mathematics, Princeton University, 2012.

I am actively looking for motivated students. If you are already at Penn, please feel free to contact me about possible research projects.

Current (co-)advisees: Yue Sheng (AMCS), Sifan Liu (Tsinghua undergraduate).

Research projects for exceptional undergraduates are available.

For PhD applicants: if you are interested to work with me, please mention this on your application to the PhD program.

I am also looking for collaborators, both in statistics and in other areas. Please feel free to contact me about potential problems of mutual interest.

This page has links to methods from my papers.  Feel free to contact me if you are interested to use them.

ePCA: github

The ePCA method for principal component analysis of exponential family data, e.g. Poisson-modeled count data. (with L.T. Liu);

EigenEdge: github

Methods for working with large random data matrices, including

  • Computing eigenvalue distributions of covariance matrices (general Marchenko-Pastur distributions).
  • Optimal statistics for testing in principal component analysis.
  • Tools for spiked covariance models: spike and cosine descriptors, optimal shrinkers.

pweight : github R. github Matlab

P-value weighting techniques for multiple hypothesis testing. These can improve power in multiple testing, if there is prior information about the individual effect sizes. Includes the iGWAS method for Genome-Wide Association Studies.
