I am a Computer Scientist with the Information Sciences 
Institute (ISI)
of
the University of Southern California. i also have an adjunct research assistant professor appointment with USC's Department of Physics and Astronomy.


My main areas of research are adiabatic quantum computation (algorithms, complexity, simulations and implementation) and computational physics (quantum and classical Monte Carlo, optimization, etc.).
