Lyubov Titova

Principal Investigator

Lyubov Titova received her Ph. D. in Physics in 2005 from the University of Notre Dame, IN in the group of Margaret Dobrowolska. She went on to do a postdoc in the group of Leigh Smith and Howard Jackson at the University of Cincinnati in 2005, working on spatially- and time-resolved photoluminescence imaging of semiconductor nanowires. In 2007, she joined the group of Frank Hegmann at the University of Alberta, Canada as an Avadh Bhatia Postdoctoral Fellow to work on time-resolved terahertz spectroscopy of semiconductors. In 2010, she became a Research Associate in the Ultrafast Nanotools Lab (PI - Frank Hegmann). She moved to the Physics Department at Worcester Polytechnic Institute in 2014.

Postdoctoral Fellows

Teng Shi

Dr. Teng Shi received her PhD at University of Cincinnati under direction of Prof. Leigh Smith. Her graduate research focused on studying the optical and electronic properties of nanostructured materials using high spectral and spatial resolution photoluminescence, photoluminescence excitation, and time-resolved photoluminescence spectroscopy. She joined WPI Ultrafast THz and Optical Spectroscopy Lab in November 2018.
