Polina Vabishchevich is a Visiting Fellow in the Microsystems and Nanotechnology Division and a Visiting Assistant Research Scientist at the Institute for Research in Electronics and Applied Physics of the University of Maryland. She received her B.S. and Ph.D. degrees in Physics from Lomonosov Moscow State University, Russia, where her graduate research was supported by the Fellowship of the President of Russia. Her research was focused on plasmonic and all-dielectric nanostructures, including their magneto-optical, nonlinear, and ultrafast responses. After obtaining her Ph.D., Polina worked on semiconductor-based metasurfaces as a Postdoctoral Appointee at Sandia National Labs, USA. She has experience in the design, fabrication, and characterization of nanostructures, with applications to frequency mixing, light emission, all-optical switching, and terahertz generation. In 2020, Polina joined the Photonics and Optomechanics Group at NIST to work with Dr. Henri Lezec and Dr. Amit Agrawal on all-dielectric and semiconductor-based metasurfaces and metadevices.
