I was recently a graduate student of Prof. P. P. Vaidyanathan in Caltech's digital signal processing (DSP) group and have just completed my Ph.D. My interests include multirate filter bank theory, data compression, and digital communications. Recently, the focus of my work has been on the design of optimal signal-adapted finite impulse response (FIR) paraunitary (PU) filter banks. I am currently working at the Jet Propulsion Laboratory as a research engineer for the Signal Processing Research Group.
