Research
My research interests include theoretical machine learning, signal processing, sparse recovery, and numerical linear algebra, and especially the applications in which some subset of these paradigms intersect. I like developing provably robust, efficient algorithms for inverse problems, sometimes in imaging applications.
Here are a few questions I've been thinking about recently:
 Is there a clear theoretical justification for the empirical success of equivariance as an inductive prior in neural architectures? What's the right way to formulate this?
 Given data, can one learn an underlying dictionary if the corresponding coefficients are not sparse, but rather come from a known generative model?
 When does equivariance with respect to the wreath product group arise in deep learning applications?
 Is it possible to characterize the class of generative models under which Fourier phase retrieval is wellconditioned?
And here are some older questions, not forgotten but on the back burner:
 What's the fastest way to rotationally align two spherical functions?
 What generalizations of (1) the restricted isometry property and (2) leverage score sampling might be useful for offgrid sparse recovery?
