Lu Chen

Lu Chen is a PML/UMD Postdoctoral Researcher in the Microsystems and Nanotechnology Division. She received a B.S. from Nankai University, China in 2012, and a Ph.D. in Physics from the University of Pittsburgh in 2018. She worked with Dr. Jeremy Levy for her doctoral research, where she focused on the broadband terahertz spectroscopy of materials at 10-nm scale and developed a tunable terahertz source on a chip scale with over 100-THz bandwidth through selective difference frequency generation at LaAlO3/SrTiO3 nanojunctions. She also studied transport properties of SrTiO3-based complex oxide nanostructures and developed extreme reconfigurable nanoelectronics at the CaZrO3/SrTiO3 interface. She has expertise in scanning probe microscopy, ultrafast optics, pulse shaping, terahertz time-domain spectroscopy, Raman microscopy, photoluminescence spectroscopy, and low temperature and high magnetic field transport measurements. Lu is currently working with Dr. Amit Agrawal on ultrafast optical spectroscopy that involves theoretical modeling, designing, fabricating, and experimentally characterizing novel nanophotonic devices including metasurfaces, metamaterials, and nanoplasmonic devices throughout the entire visible, mid-infrared, and terahertz parts of the spectrum.
