Hugo Destaillats

Hugo Destaillats is a Staff Scientist at the Environmental Energy Technologies Division, and Deputy Leader of the Indoor Environment Group. He has been at LBNL since 2003. Hugo obtained a Ph.D. in Chemistry from the University of Buenos Aires (Argentina), and has been a postdoctoral researcher at the California Institute of Technology.

Hugo’s research interests are at the interface between environmental chemistry, human health and energy efficiency of the built environment. He leads efforts to understand exposure to harmful pollutants, and to develop and characterize new building materials and technologies that improve the environmental quality of the human habitat. While most of his research is related with indoor air quality, Hugo is also active in LBNL’s Heat Island Program, working towards the development and accelerated rating of novel “cool” roofing materials that help save energy and mitigate the urban heat island effect.

Marc Fischer

Dr. Marc Fischer is staff scientist in the Sustainable Energy Systems group and Environmental Energy Technology Division at the Lawrence Berkeley National Laboratory (LBNL), and is an adjunct associate research scientists at the Air Quality Research Center at the University of California, Davis. Dr. Fischer has co-authored more than 50 refereed journal publications. Fischer's current work focuses on atmospheric studies of natural and anthropogenic processes affecting greenhouse (GHG) gases (and other atmospheric constituents, and development of sustainable solutions to energy and environmental problems. As part of ongoing work, Fischer and colleagues are quantifying the sources of California's GHG emissions, their long-term trends, and identifying cost-effective options to mitigate emissions.

Haley Gilbert

Haley is the Principal Research Associate in the Heat Island Group, leading our Cool Communities efforts to promote the use of cool roofs and cool pavements. She also is the primary contact for the group's industrial partners and assists with outreach efforts.

Ronnen Levinson

Dr. Ronnen Levinson is a Staff Scientist and Leader of the Heat Island Group at Lawrence Berkeley National Laboratory (LBNL) in Berkeley, California. Within his research portfolio he develops cool roof, wall, and pavement materials; improves methods for the measurement of solar reflectance; and quantifies the energy and environmental benefits of cool surfaces. He serves on the boards and technical committees of the Cool Roof Rating Council and the Global Cool Cities Alliance, and advises policymakers, code officials, utilities, and building rating programs about cool surfaces. He holds a B.S. in engineering physics from Cornell University and an M.S. and a Ph.D. in mechanical engineering from the University of California at Berkeley. He has authored or co-authored over 60 publications, and serves on the editorial boards of Energy & Buildings and Advances in Building Energy Research.

Benjamin Mandel

Ben is a Graduate Student Assistant providing research and technical support for Dr. Arthur Rosenfeld and the Heat Island Group while pursuing a Masters in Public Policy at U.C. Berkeley.

Mel Pomerantz

Melvin Pomerantz has been with the Heat Island project since 1994. His main focus is on pavements, as well as some involvement in studies of roofs. His latest activity is the critical analysis of the costs and benefits of cooler surfaces. Before LBNL, he did research on solid-state physics at the IBM Research Laboratories in Yorktown Heights, NY and Almaden, CA. Dr. Pomerantz was a Fulbright Fellow in France, a Meyerhof Visiting Fellow in Israel, and is a Fellow of the American Physical Society. He has taught physics courses at the University of California since 1998. Before that, he taught at the Polytechnic Institute of New York, Mercy College and the State University of NY at Purchase.

Pablo Rosado

Pablo is a Graduate Student Research Assistant from the University of California, Berkeley, where he is currently pursuing a Ph.D. in Mechanical Engineering.

Mohamad Sleiman

Mohamad Sleiman is an Environmental Chemist and a Research Scientist at Lawrence Berkeley National Laboratory. He leads the experimental effort for the development of accelerated aging protocols to mimic the loss of solar reflectance of roofing materials caused by long-term natural exposure. His research also focuses on self-cleaning technologies and understanding the fate and chemistry of indoor and outdoor pollutants and their effects on air quality and public health.
