Wenqi Zhu (Fed)

Wenqi Zhu is a research scientist in the Microsystems and Nanotechnology Division. He received a B.S. from Tsinghua University in 2005 and a M.E. from the University of Utah in 2008, both in Electrical Engineering. He received his Ph. D. degree in Engineering Sciences from Harvard University in 2014, where he studied classical and quantum-mechanical effects in plasmonic nanogap antennas for surface-enhanced Raman spectroscopy of single molecules. He is currently working on developing meta-photonic devices that combines the concepts of nanophotonics and laser cooling for metrology and quantum computing. His general research interests include metasurfaces, photonic integrated circuits, neutral atom trapping, and ion traps.
