Bio and CV;     Research and teaching statements (2012);     tenure packet (2010) Note: As of late 2014, I am also a consulting senior research scientist at the new Simons Center for Data Analysis in NYC, working on algorithms and software for neural spike sorting, cryo-EM, and other inverse problems. I will spend a significant fraction of each year there over the period 2015-2018.

Publications, talks, and notes

Our group: Larry (Yuxiang) Liu (Physics) started as a graduate student in scattering from periodized bodies of revolution in Jan 2013, partially supported by NSF and the Neukom Institute Congratulations Larry on receiving the Ph.D. in June 2016! Larry is moving in Oct 2016 to a postdoc in applied physics at Yale.
Paula Chen '17. Senior thesis on improving spike sorting algorithms.
Matthew Jin '17. NSF-funded undergraduate researcher measuring topology statistics of nodal sets of random plane waves.
Prospective grad students: although the 1st-yr qual is pure-math oriented, the 2nd-yr need not be, and we have an expanding applied/computational group at Dartmouth. Do apply!

Seminars and conferences: I started and co-run the Applied and Computational Mathematics Seminar. I was the main organizer of the NSF-CBMS Conference of Fast Direct Solvers for Elliptic PDE, June 23-29, 2014. Until Sept 2015 I was faculty adviser for our SIAM Chapter.
