Jessie Zhang (Fed)

Chen (Jessie) Zhang is the Assistant NanoFab Manager in the NanoFab Operations Group. She received a B.S. in Materials Science from Shanghai Jiao Tong University, China and a master and Ph.D. in Materials Science from Auburn University, where her doctoral research focused on nickel-titanium and nickel-titanium-hafnium shape-memory alloy development for automobile, sensor and medical device application. Jessie has over 15 years of industrial experience in materials development, semiconductor processing, and project management. She began her career as a visiting scientist at Johnson Controls, Inc., developing nickel-titanium-based memory alloys for automotive and microelectromechanical systems applications. She then worked at Photronics as a senior processing engineer overseeing a sub-micron photomask processing line, and later joined Paratek Microwave, Inc. (now part of BlackBerry Limited), where she held both engineering and management positions developing and fabricating radio frequency microwave devices. Prior to joining NIST, she was a principle engineer at BAE Systems, Inc., where she was responsible for process design, development, and integration of infrared imaging and detection devices. As Assistant NanoFab Manager, Jessie has a broad range of overall group management responsibilities. Jessie oversees all technical programs including managing remote nanofabrication projects, developing process library, setting up statistical process control monitoring, developing advanced processes and expanding NanoFab capabilities. Jessie also assists NanoFab daily operation and oversees NanoFab intern program.
