Adjunct assistant professor of computer science at the Columbia University Department of Computer Science. I wrote my Ph.D. in atomic physics at CCNY (City College of New York). My thesis is on correlated double electron photoionization of helium. My interests in physics are atomic physics (especially ionization processes in laser fields), statistical physics, and scattering theory. Some of my recent physics output can even be found online. My main interests in mathematics and computer science are symbolic mathematics on computers, and numerical analysis.
