I am a Ph.D. candidate in the Department of Electrical Engineering at the University of Washington. I work with Eve Riskin and Richard Ladner on the MobileASL project. I am working on the Rate-Distortion-Complexity (R-D-C) analysis of H.264 encoder and looking at approaches for selecting optimal encoding parameters for R-D-C optimization. My research interests includes video coding and perceptual audio coding.

I obtained my Masters in Electrical Engineering at New Mexico State University in 2005. At NMSU, I worked with Charles Creusere for developing a scalable perceptual metric for evaluating audio quality. I also worked with Raphael Lyman for developing an Autoconfigurable receiver. Prior to grad school, I worked at Wipro Technologies in their Multimedia and DSP group porting different audio codecs and post processing algorithms to an embedded platform. I have interned in Nvidia in Summer 2005 and Thomson Corporate Research in Summer 2007.
