Janet Sheung Visiting Assistant Professor of Physics

Janet Sheung received her BS in physics from California Institute of Technology, her MS and PhD in physics from the University of Illinois. An experimental biophysicist, she studies the physical processes of cellular regeneration and develops optical instruments which extends the limits of what humans can see. She teaches introductory physics, advanced physics laboratory, and an advanced topics course in biophysics.

Teaching Interests

Janet Sheung teaches the first two semesters of introductory physics, Physics 113 and 114, advanced physics laboratory, Physics 202/203, and will teach an advanced topics course in biophysics starting Spring 2019, Physics 375. She is committed to introducing cutting-edge experimental techniques into the undergraduate curriculum by custom building research equipment at reduced costs.

Research Interests

Janet is an experimental biophysicist with broad research interests, and have co-authored articles in astrophysics, engineering, as well as single-molecule and cellular biophysics. She and her students are currently investigating the physical processes involved in regeneration of the unicellular protist, Stentor Coeruleus, and will continue this work at the Marine Biological Laboratory during the summer. She is also working with one student in a collaborative project with Argonne National Laboratory, to develop diffraction grating metrology capability on the Long Trace Profiler.
