David S. Ginley
David S. Ginley's current activities are in the areas of the general class of defective transition metal oxides including high temperature superconductors, LiTMO2 rechargable Li battery materials, ferroelectric materials, transparent conducting oxides and electrochromic materials.
Dr. Mascarenhas' work focuses on spectroscopic research on semiconductor materials for photonics and advanced solar cells. He has done extensive research on harnessing the material consequences of semiconductor alloy instabilities such as spontaneous ordering and spontaneous composition modulation for optoelectronic applications.
Dr. Thresher has more than 40 years of research, development, engineering, and management experience in wind technology, plant engineering, and aerospace systems. He has been a strategist for the initiation of a national research program to develop offshore wind, wave, tidal and current energy technology.
Dr. Wei is a world-renowned scientist in computational materials science. His research is focused on developing first-principles electronic structure theory of functional materials, especially for semiconductors, photovoltaic materials, and other materials for energy related applications.
Research Fellows Emeriti
Research Fellow Emeritus
Dr. Ahrenkiel's area of specialization is the measurement and characterization of photovoltaic cells and materials. He is one of the world experts in the area of carrier recombination and carrier lifetime. He invented a unique technique for measuring the excess carrier lifetime in materials.
