Research

I am a first year Ph.D. student at Computer Science Department of UCLA under the supervision of Stefano Soatto as a member of UCLA Vision Lab.

My general research interests are in computer vision and applications of geometry and machine learning in this field. I am most interested in the use of mathematical techniques coming from discrete differential geometry, spectral graph theory, combinatorial optimization and statistical inference for the formulation of algorithms for computer vision problems, e.g. segmentation, registration, tracking, and image matching.
