Assistant Professor, Applied Mathematics |
I joined the department of Applied Math in fall 2014. Previously I was a Herman Goldstine Postdoctoral fellow in Mathematical Sciences at IBM Research in Yorktown Heights, NY, and a postdoctoral fellow via the Fondation Sciences MathÃ©matiques de Paris at Paris 6 (JLL lab) with Patrick Combettes, and co-advised by Volkan Cevher (EPFL). Until 2011, I was at Caltech where I did my doctoral work under Emmanuel CandÃ¨s.

Availability fall 2015: I am typically in the late afternoons
I am interested in collaborating with mathematicians, scientists and engineers on diverse projects.
Optimization: first-order methods, quasi-Newton methods, primal-dual algorithms, convex analysis
Numerical linear algebra: randomization and its interplay with optimization methods
Mathematical applications: compressed sensing and variants, matrix completion and variants (robust PCA…), non-negative matrix factorization and end-member detection, sparse SVM
Physical applications: radar ADC using compressed sensing, quantum tomography, MRI, medical imaging, IMRT, renewable energy, big-data
I am looking for motivated students to work with. If you are not currently a student, please apply to our undergraduate or graduate program and your application will receive full consideration.
