Welcome! Here is my CV.

To find out about our group's research, and my contact details, see the new Center for Computational Mathematics, Flatiron Institute, Simons Foundation, and the Numerical Analysis area.

Many of my papers are on arXiv and most are in google scholar. Research and teaching from 2017 and earlier is available at my former academic page as a professor of mathematics at Dartmouth College.

You can find some of my numerical software projects on github and via CCM's software page.

We seek high-quality submissions to the journal Adv. Comput. Math., for which I am co-Editor in Chief. We have a special issue on integral equations, deadline August 2020 2021. In 2019 I was the main organizer for Flatiron-Wide Algorithms and Mathematics (FWAM).

Now on Thursdays at 10:30am (on zoom) we run our weekly CCM (formerly numerical analysis) seminar, on topics including signal processing, PDE, numerical analysis, fast algorithms, data analysis, statistics, deep learning, and neuroscience.
