NotesI specifically chose the above photo, crow's feet and all, just to highlight the point that research should be fun!
This page contains a description of my current research interests, recent papers and papers awaiting publication, and recent seminar presentations. Reprints of scientific papers that are already published can be found under "publications" while other writings can be found under (what else?) "other writings."

Current Research InterestsMy research interests are in the broad area of system and control theory, and its applications. After spending an entire lifetime "ducking" probability theory, at the moment I am working on problems in stochastic realization, specifically approximating high-order Markov and hidden Markov processes by lower-order processes, and the large deviation properties of such processes. Recently I have also developed an interest in compressed sensing theory. On the applications front, I am interested in applying these (or any other appropriate) ideas to problems in computational biology with emphasis on cancer.
