Research Interests

I am an assistant professor in the Department of Applied Mathematics at the Naval Postgraduate School.

Prior to my current appointment, I worked with with Prof. Tim Warburton in the Department of Mathematics at Virginia Tech. Prior to that, I was the J. H. Wilkinson Fellow in the Mathematics and Computer Science Division at Argonne National Laboratory. As a Ph.D. student, I was an active developer for the Chebfun project (source code available on GitHub).

Together with Robert Bassett, I co-organize the NPS Junior Faculty Research Seminar. If you're a junior faculty member at NPS, please let one of us know if you're interested in giving a talk!
