Observational Astronomy: Research
My research work is focused on improving our understanding of cool stars and brown dwarfs. I make use of both ground-based and space-based telescopes to characterize these faint, cool objects. Most of my attention is on 2MASSW 1207334-393254. This young brown dwarf, is only 2.5% the mass of the Sun, but it is surrounded by a disk of gas and dust. It has a companion which is only 0.3-0.8% the mass of the Sun, making it a "planetary mass brown dwarf."

Physics and Astronomy: Teaching
I have taught introductory and advanced classes in both physics and astronomy. In Fall 2007, I am teaching PHYS201H, the honors algebra-based introductory physics class. In Spring 2008, I am teaching PHYS208H, the honors calculus-based introductory physics class.
I generally have research opportunities for undergraduate and graduate students in both the summer and the academic year.
Look for me in facebook.
