I work on problems in statistics, machine learning, optimization, etc. Some of my current research interests are:

  • High-dimensional statistics
  • Network models
  • Unsupervised and semisupervised learning
  • Clustering and community detection
  • Causal graphical models
  • Kernel methods
  • Representation learning
  • Optimization
  • Quantitative Finance

I did my PhD at UC Berkeley with Martin Wainwright and a post-doc at University of Michigan with Liza Levina and Long Nguyen. You can learn more about me from my CV.
