Hongtao Zhang

Hongtao Zhang is a CNST/UMASS Postdoctoral Researcher in the Nanofabrication Research Group. He received a B.S. in Mechanical Engineering and Computer Science from the University of Shanghai for Science and Technology, China and a Ph.D. in Physics from Stevens Institute of Technology. His doctoral research focused on developing a portable optical fiber-based sensing system for use in high-speed weigh-in-motion (WIM) measurements to capture a vehicle’s axle weights, gross weight, and dimensions as it drives over a measurement site.  Before joining the CNST, he worked as a research scientist at L. C. Pegasus Corporation, where he developed a high speed optical fiber demodulation system, and as a research fellow at the Center for Electromagnetic Materials and Optical Systems at the University of Massachusetts Lowell, where he simulated and fabricated miniature optical fiber sensor systems to detect pressure in the arteries of cardiac patients. Hongtao is working with Gregg Gallatin and J. Alexander Liddle in collaboration with the Center for Hierarchical Manufacturing at University of Massachusetts Amherst on the metrology of roll-to-roll nanoimprint technology.
