In Fall 2018, I taught CO673/CS794, Optimization for Data Science. This course has its website on UWaterloo Learn. For those without Learn access yet, you can access course-information material and Problem Set 1 here.

Research and Publications

My research interests are continuous optimization and data science. More specifically, I am interested in:

  • Efficient algorithms for optimization,
  • Applications of optimization to data science,
  • Numerical linear algebra in optimization and data science
  • Complexity issues in continuous optimization.

I have also in the past been interested in geometric problems arising in scientific computing and numerical linear algebra arising in differential equations.
