Xuemei May Cheng is a Professor of Physics and Dean of Graduate Studies at ���ճԹ�. She received her B.S. in Physics and M.S. in Microelectronics and Solid-State Electronics from Nanjing University. She continued her graduate studies at Johns Hopkins University, where she earned her M.A. and Ph.D. in Condensed Matter Physics in 2004 and 2006, respectively. After a postdoctoral fellowship in the X-ray Science Division of Argonne National Laboratory, she joined ���ճԹ�'s faculty in 2009. She has taught a broad range of physics lectures, laboratories, and seminars at both undergraduate and graduate levels. 

Her research focuses on the fabrication and characterization of nanomaterials as well as their applications in magnetic data storage and biomedical engineering. With her expertise in nanofabrication, synchrotron x-ray spectra, and magnetic imaging, she is interested in exploring topological spin textures (magnetic skyrmions and vortices) in magnetic nanomaterials, interface magnetism, 2D materials, multiferroic materials, and dimensionality-controlled nanostructures. Recently, she has expanded her research to quantum materials and quantum sensing. She has published over 70 research articles in peer-reviewed journals, such as Science, Nature Physics, Advanced Materials, Nano Letters, Physical Review Letters. She has established a robust and well-resourced research program at ���ճԹ� with support from the College and external grants. She has received over $6.5M rom the National Science Foundation (NSF) to fund her research, including an NSF CAREER award during her second year at the College and a recent $5M NSF ExpandQISE team grant with her as the Principal Investigator for a Quantum Information Science and Engineering (QISE) Center. She has engaged over 40 undergraduate and 7 graduate students in her research. Undergraduate and graduate students collaborate as dynamic partners in her lab and often participate as co-authors of her publications.
