Janice is a research scientist in experimental condensed matter physics at Johns Hopkins University. She is also a staff member at the Applied Physics Laboratory and has helped develop an online physics course for the Center for Talented Youth. Her research interests include nanoscale physics, scanning probe microscopy, superconductivity, and energy related materials. Currently she is working on graphene in collaboration with Nina Marković's group. Graphene is an atomically thin sheet of carbon atoms which has remarkable properties. Janice got her Ph.D. from Stanford University where she worked with Kathryn Moler. Prior to coming to Johns Hopkins, she was a postdoc at Cornell and then taught physics for two years at Texas A&M.

NEWS:   Janice is a recipient of the M. Hildred Blewett Scholarship from the American Physical Society in 2008 and 2009.  See the APS News articles in the Oct. 2008 and Aug./Sept. 2009 issues.
