Research Interests

My research primarily lives in the world of techniques, methods, and algorithm development for radio astronomy. I like finding challenging astronomical imaging problems that either let us apply existing state-of-the-art methods to produce an interesting result, or push us to develop new methods and algorithms to get the necessary science done.

Below is a selection of papers.
