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 our group's software page.

Most Wednesdays at 10:30am we run our weekly numerical analysis / CCM seminar, on topics including signal processing, PDE, numerical analysis, fast algorithms, data analysis, statistics, and neuroscience.
