Arash A. Amini

Associate Professor of Statistics at UCLA.


I work at the intersection of statistics, machine learning, optimization, etc. Some of my current research interests are:

  • High-dimensional data analysis
  • Nonparametric estimation
  • Inference on networks
  • Optimization esp. convex relaxations
  • Functional data analysis
  • Graphical models
  • 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.
