Brian A. Stewart

Professor of Physics Brian Stewart at Wesleyan University studies collisions of small molecules.  Fundamental to chemistry, collisions of small molecules are also an ideal context for the study of few-body dynamics, and ultimately some of the most fundamental questions in physics.

Current work focuses on the mechanism of vibrational energy transfer and chemical reaction of very rapidly rotating molecules.
