Our research fellows advise on the strategic direction of science and technology research at NREL and ensure our work meets the highest standards for quality and objectivity.
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.
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.
Arthur J. Nozik
Senior Research Fellow Emeritus
Dr. Nozik’s work focuses on photoelectrochemistry, solid state physics, semiconductor nanoscience, hot carrier effects, Third Generation solar photon conversion, and related interdisciplinary science. He has 11 U.S. patents and over 250 published papers.
Research Fellow Emeritus
Dr. Seibert's current research interests include primary processes of and water-oxidation in oxygenic photosynthesis, structure and function of [Fe]-hydrogenases, molecular engineering of hydrogenases, expression profiling in green algae, and photobiological hydrogen production.
