Charles Collett
Assistant Professor of Physics
A native of Clinton, N.Y., Charles Collett received a B.S. from Haverford College, and an M.S. and Ph.D. from Northwestern University, all in physics. An experimental low temperature experimentalist, he does research on molecular nanomagnets, a class of quantum spin systems, with a focus on electron spin resonance spectroscopy and quantum computing. He was previously a visiting assistant professor at Hamilton and Amherst Colleges, and most recently was an assistant professor at Muhlenberg College.
