I am a Doctoral Candidate in Information Management and Systems in the School of Information (iSchool) at UC Berkeley. My doctorate is part of the designated emphasis in communication, computation, and statistics (DECCS).
I am also an MA candidate in the Berkeley Statistics department and finishing up Paul Wilmott's Certificate in Quantitative Finance.

The University of California was recently (Dec 1, 2009) awarded a patent on part of the work I have done in my ischool dissertation (patent 7,627,510).

My academic & dissertation advisor is Yale Braunstein. I am also adviced by Dr. Maarten Sierhuis at CMU/Silicon Valley.
