Bio and CV;     Professional statement (2016) Note: As of November 2017, I have moved full time to the Flatiron Institute in NYC, heading the Numerical Analysis effort in the brand-new Center for Computational Mathematics (CCM). We work on computational methods, and software implementations, including PDEs, neuroscience, imaging, data analysis, statistics, and numerical libraries.

Seminars and conferences: I started and ran Applied and Computational Mathematics Seminar from 2006-2015. I was the main organizer for the 100-person workshop Modern Advances in Computational and Applied Mathematics at Yale, June 2017.

Recent group members:

Paula Chen '17. Senior thesis on spike sorting algorithms for neural electrical recordings with overlapping spikes. Ph.D program at Brown, DAM, started Sept 2018.
Matthew Jin '17. NSF-funded undergraduate researcher measuring topology statistics of nodal sets of random plane waves. Now a data-sci and engineer at Microsoft.
Larry (Yuxiang) Liu, Ph.D June 2016 (Physics). Thesis. Topic: fast algorithms for Helmholtz and Maxwell scattering from periodic arrays of obstacles via the MFS. After a postdoc in applied physics with Owen Miller's group at Yale, Larry became a quant at RBS, Optiver, and now Citadel.
Min Hyung Cho. Computational optics, electromagnetics, fast algorithms, layered media. IACM Instructor July 2012 - June 2015. Tenure-track at UMASS Lowell, started July 2015.
Lin Zhao, Ph.D June 2015. Thesis. Topic: integral equations for Laplace eigenvalue and doubly-periodic electrostatics and Stokes flow problems. Lin went into investment research at INTECH, now a software engineer at Bloomberg.
Adrianna Gillman. Research areas: fast direct solvers, PDEs, integral equations. JWY Instructor July 2011 - June 2014. Tenure-track at Rice started July 2014; now at CU Boulder.

Prospective grad students: although the 1st-yr qual includes foundational pure math, the 2nd-yr can be applied, and there is an excellent applied/computational group at Dartmouth. Do apply!
