Former RASEI Contributors

Howard Branz, Ph.D., a principal scientist with NREL's National Center for Photovoltaics, and a nationally and internationally renowned scientist with achievements in physics, materials science, and device engineering related to renewable energy. Branz has led NREL's amorphous silicon photovoltaic development for more than 5 years and all of NREL's silicon research. Primary research interests include film crystal silicon photovoltaics; defects, metastability, and diffusion in semiconductors; amorphous semiconductors; mechanisms of film and epitaxial silicon growth; and nanostructured black silicon antireflection.



Former RASEI Director Michael Knotek

Michael brought more than forty years of energy science and technology expertise to the University of Colorado Boulder. He served as a consultant specializing in transitions and creating new research directions in agency and institutional programs, projects, and major research facilities, and has led several teams developing multi-billion dollar proposals and contracts for the Department of Energy (DOE). He has been involved in strategic planning and project management for multidisciplinary and multi-institutional programs and facilities, including DOE biological programs, high-performance computing, environmental research, and national facilities such as synchrotrons. Knotek formerly served as senior science and technology adviser to the Secretary of Energy at DOE; distinguished science executive at Argonne National Laboratory; chief technology officer with the Battelle Memorial Institute; chairman of the National Synchrotron Light Source research facility at Brookhaven National Laboratory; and associate laboratory director for Environmental and Energy Sciences at Pacific Northwest National Laboratory. Knotek is a fellow of the American Association for the Advancement of Science and the American Physical Society.


Carl-KovalDr. Carl Koval, RASEI’s founding Associate Director for Research and was instrumental in developing RASEI from a concept (EI) to a university initiative in renewable energy.

Carl served as CHEM Department Chair from 1998-2001. Beginning in 2006, he has played several key roles in the development of the Colorado Renewable Energy Collaboratory, including serving as Institutional Coordinator for the Boulder Campus and on the Project Management Team for the Center for Revolutionary Solar Photoconversion (CRSP). In 2006 through a Campus-wide search process, he was chosen to be the first Faculty Director of the Renewable and Sustainable Energy Initiative (EI) at the University of Colorado at Boulder. In June 2009 he accomplished the key objective of the EI when the CU Regents approved the creation of the Renewable and Sustainable Energy Institute (RASEI).




Rebecca Kauffman - RASEI Advisory Board

Rebecca Kauffman
President & COO, Southern Ute Alternative Energy Investment Fund


Rebecca Kauffman is President and Chief Operating Officer of Southern Ute Alternative Energy, an operating entity of the Southern Ute Growth Fund. The Southern Ute Growth Fund was established and is operated by the Southern Ute Indian Tribe. The Growth Fund represents a diverse group of businesses and investments, functioning as a merchant bank with direct ownership of its many operating companies. Its offices are located in Ignacio, Colorado, with interests and businesses located in several states across America. Rebecca joined the Southern Ute Growth Fund in August of 2007 to explore business expansion into the alternative and renewable energy sectors. Prior to joining the Growth Fund, she was an Executive Director at Morgan Stanley Inc. within the Institutional Operations Security Group in strategy and planning. Her work focused on operations and technology infrastructure development. Rebecca has extensive project experience in large capital projects related to building and optimizing supply chains, operations, and infrastructure. The majority of her work has been in the manufacturing and service industries. She has an BS in biology from the University of Oregon and MS in environmental engineering from Stanford University.


Pat Moriarty, Ph.D., a senior engineer at NREL's National Wind Technology Center, where he spends most of his time researching statistical loads extrapolation techniques for wind turbine design. He has developed new design techniques that enable industry to more reliably predict loads and produce cheaper designs. This work is included in the IEC International design standard 61400-1, edition 3, published in 2004. Moriarty continues to research wind turbine design and aeroacoustics of wind turbines. He is also involved in the development and continuing improvement of empirical codes for noise prediction and has developed and helped improve current aerodynamic prediction routines used in wind turbine simulation programs. He is the associate editor of the Journal of Solar Energy Engineering. Prior to joining NREL, Moriarty spent nearly two years at RANN, Inc. examining active control of wind turbines under subcontract from NREL. He also worked at NASA Ames Research Center and has collaborated with Boeing, Florida State University, and NASA Langley Research Center. He helped start the Center for Research and Education in Wind (CREW) and has been an instructor in wind energy at CU-Boulder since 2006.

Look Professor of chemical engineering in the College of Engineering and Applied Science and co-director of the Membrane and Applied Science Center (MAST) at CU-Boulder. Noble and his group are studying the use of ionic liquids for gas separations with plans to evaluate various ionic liquids and complexation chemistry to tailor the material properties to the feed mixture being separated. Various configurations, including composite polymer/IL structures, as well as the incorporation of complexation chemistry and zeolites, are being studied. The group has also developed an apparatus to measure both solubility and diffusivity of gases in ionic liquids. Noble also leads a research group that synthesizes several different zeolite membranes on the interior of microporous alumina and stainless steel tubes. Gas, vapor, and pervaporation permeation studies are conducted to evaluate the performance of the membranes for various applications. Highly selective separations for carbon dioxide/methane, organic isomer vapor and organic/water liquid phase separations have been accomplished.
