About Me

I am leading Impulsonic, Inc. Impulsonic was founded by students and researchers from the GAMMA lab in the Computer Science department at the University of North Carolina at Chapel Hill. Over the past six years, the GAMMA lab has leveraged its high-performance computer graphics expertise to develop cutting-edge technology for real-time sound synthesis and rendering for a variety of applications, ranging from movies and games, to architectural design and outdoor noise modeling.

I received a Ph.D. from the Computer Science Department at UNC-Chapel Hill. My advisor was Dinesh Manocha. My research interests include: sound rendering (synthesis, propagation, and 3D audio rendering), computer graphics (ray tracing, visibility, and gpgpu).

I did my undergraduate (B.Tech.) in Computer Science from IIT Bombay, India. I was an intern at Microsoft Research during Summer 2008 and Summer 2009.
