Yiliang Bao

Yiliang Bao is a Guest Researcher in the Microsystems and Nanotechnology Division, Physical Measurement Laboratory, National Institute of Standards and Technology. She received her Ph.D. in Physics from the University of Florida. Her doctoral research focused on the measurement of the Casimir force on a surface with nanoscale structures using MEMS torsional oscillator. She is now working with Jason J. Gorman on optomechanical sensing, including optomechanical accelerometers and silicon nitride resonators for quantum optomechanics.
