David Allen

University of Texas

David Allen is the author of six books and more than 200 papers in areas ranging from coal liquefaction and heavy oil chemistry to the chemistry of urban atmospheres. For the past decade, his work has focused primarily on urban air quality and the development of materials for environmental and engineering education. Allen was a lead investigator for the first and second Texas Air Quality Studies, which involved hundreds of researchers drawn from around the world, and which have had a substantial impact on the direction of air quality policies in Texas. He has developed environmental educational materials for engineering curricula and for the university's core curriculum, as well as engineering education materials for high school students.

David Kittelson

University of Minnesota

David Kittelson's research interests include sampling and characterization of particles from high-temperature, high-pressure streams; characterization of devices for removing particulate matter from combustion products; energy conversion and the production and use of alternative fuels; dynamics of diesel exhaust and other carbonaceous aerosols; electronic engine control; measurement and control of spark ignition engine knock; engine sensors, control, and on-board diagnostics. He also studies the performance of alcohols and other alternate fuels in engines; continuous measurement of airborne particulate sulfur, carbon, and nitrogen; measurements of ultrafine particles in gases and liquids; and megasonic cleaning of silicon wafers.

Charles Powars

St. Croix Research

Charles Powars is the principal of St. Croix Research, a consulting firm based in Palo Alto, California. Powars has been involved in alternative transportation fuels research, development, demonstration and policy planning since 1980. His recent work has focused on LNG-fueled trucks and buses. He consults with equipment manufacturers to develop LNG fuel systems, fleets to successfully operate LNG stations and vehicles and the State of California to project future LNG transportation fuel demand and potential supply sources.

Brent Bailey

Coordinating Research Council

Brent Bailey is the executive director of the Coordinating Research Council. The CRC is a non-profit organization that directs, through committee action, engineering and environmental studies on the interaction between automotive/other mobility equipment and petroleum products. The Sustaining Members of CRC are the American Petroleum Institute and a group of automobile manufacturer members (Chrysler, Daimler, Ford, General Motors, Honda, Mitsubishi, Nissan, Toyota and Volkswagen). CRC research programs are managed by five technical committees (Advanced/Vehicle/Fuel/Lubricants, Atmospheric Impacts, Emissions, Performance and Aviation).

Robert F. Sawyer

University of California, Berkeley/Sawyer Associates

During his 44 year career at the University of California, Berkeley as a professor of mechanical engineering, Robert Sawyer's teaching and research included rocket propulsion, energy conservation, combustion, air pollution and regulatory policy. He has authored more than 350 publications including two books. He chaired the Energy and Resources Group and was selected to be the first Class of 1935 Professor of Energy at Berkeley. From 2003-2005, he headed the University of California Education Abroad Program in London. In January 2006, Sawyer left the University of California to accept the appointment by then-Governor Arnold Schwarzenegger to head the California Air Resources Board, a position he held through June 2007. Currently he is the Class of 1935 Professor of Energy Emeritus at UC Berkeley. He is a fellow of the Society of Automotive Engineers and a member of the United States National Academy of Engineering.
