James W. Van Howe

James Van Howe

Associate Professor of Physics

Professor van Howe began his physics career as an undergraduate at Augustana College in 1996 but finished his B.A. in physics at University of Chicago in 2001. He received his M.S. and Ph.D. in  physics from Cornell University in 2005 and 2007 respectively. He was a visiting scientist at Institut National de la Recherche Scientifique in Montreal, QC  in the summer of 2012 and 2016 for work on ultrafast optical signal processing. Currently, he is on professional leave until the fall of 2020 at INRS in Montreal to research quantum optical signal processing.

In addition to teaching and developing curriculum for undergraduate physics courses and laboratory, he directs research and maintains a laboratory in experimental optics.

Research interests

Optical signal processing, ultrafast optics, nonlinear optics, fiber optics, laser sources, photonics, and quantum optics.
