Teaching Research Publications
I have been a Visiting Assistant Professor at Duke Mathematics department, since August 2009.
I work with Dr. Mauro Maggioni on novel construction of multiscale dictionaries for point-cloud data with applications to images.
I graduated with a PhD in Applied Mathematics from the University of Minnesota in July 2009.
My advisor was Dr. Gilad Lerman, and my dissertation work was on subspace clustering.
