Duane teaches environmental planning and policy, infrastructure planning, environmental impacts of energy systems, land use planning, environmentally sustainable community development, and the impacts of urban development on fragile natural systems. He is particularly interested in how institutional structures can be modified to address competing social values. He is therefore studying law and legal institutions in greater detail, since they dominate decision-making in the modern administrative state. His primary institutional focus is domestic, but has also worked in or traveled in over thirty countries and has supervised graduate students in over a dozen other countries. He has published on a wide variety of topics from electricity regulation in California to community participation in ecosystems management.

Ashok Gadgil received an award from San Jose’s (CA) Tech Museum of Innovation, which honors people who use technology to help humanity, for developing a water purification system that kills bacteria with ultraviolet light. The system, called UV Waterworks and marketed by WaterHealth International, Inc., is used daily by about 300,000 people in Mexico, the Philippines, and several other countries. Several systems will soon be installed in his native India. Money is currently being raised to install the system in tsunami-stricken regions of Sri Lanka and India. His invention appeared in Forbes Magazine in 2003. Ashok Gadgil is also developing a cheap and effective way to provide safe drinking water to 60 million Bangladeshis who live under the specter of arsenic poisoning. His idea is to create arsenic filters from coal ash, the fine gray powder that piles up at the bottom of furnaces at all coal-fired power stations, waiting to be discarded. Although still in the investigational stage, Gadgil’s technique would involve coating the ash with a compound that attracts arsenic, filling teabag-sized pouches with the powder, and distributing the filters throughout the countryside, one per family per day. Water drawn from any one of the millions of contaminated wells that dot Bangladesh could then be poured through the filter and safely consumed. Gadgil has numerous publications spanning the areas of drinking water efficiency and indoor air quality.

Harrison Fraker is an award winning architect and Founding Partner of the Princeton Energy Group. Recently, he led an initiative to design three transit-oriented neighborhoods for Tianjin, China, a city of 11 million. The idea in this design is not just green buildings but whole systems, encouraging officials to integrate planning for power, water, waste and transportation for better environmental results. Fraker teaches design studio and architectural internship program and current research activity includes affordable manufactured housing, urban design, sustainable development and ecological design.

Chemist Paul Alivisatos's pioneering research into tiny nanocrystals and nanorods is paying off in big ways. Chemically-pure clusters of anywhere from 100 to 100,000 atoms, Alivisatos's nanocystals and nanorods have myriad applications that impact the macroworld -- from tagging biological samples for genetic analysis and drug discovery to the creation of plastic solar cells that can be painted onto any surface. Alivisatos's latest small tech innovation nanotechnology is potentially a giant leap in solar energy. Several months ago, the group reported a technique to make flexible solar cells that could someday provide power for next-generation mobile phones, handheld computers, and wearable electronics. The first prototypes boast efficiencies of 1.7 percent. This means that they can only convert 1.7 percent of the energy they receive from the sun into electricity, far less than the 10 percent efficiency of today's commercial photovoltaics. The contributions of Alivisatos and his colleague Eicke Weber hold the promise to drop the cost of solar cells by an order of magnitude, with a related movement away from poly-crystalline silicon to amorphous silicon, plastic, and organic cells.

Alexander Skabardonis is Adjunct Professor in the Department of Civil Engineering, and Director of California PATH at the University of California at Berkeley. His major research interests and areas of expertise include traffic flow theory, traffic management and control systems, transportation modeling and analysis, design and operation of transportation facilities, intelligent transportation systems, energy and the environment.

Dan Kammen founded and directs the unique Renewable and Appropriate Energy Laboratory, cited by many as the only ‘one stop’ site for energy science and engineering projects that are merged with energy finance and economics, sociology, market, and environmental impact studies. Recent RAEL contributions include: (i) significantly supporting and strengthening the burgeoning solar photovoltaic industries in East Africa, that have become the free-market model for a large number of nations; (ii) bringing the potential of continent-wide sustainable biofuel industries with major energy and health impacts to the attention of world leaders; (iii) highlighting the job benefits of clean energy investments, a story that became central to the adoption of clean energy standards in a number of states as well as a focal point of several national election campaigns; and (iv) focusing national attention on the federal under-investment in energy research, development, and deployment. He is co-author of Should We Risk It? Exploring Environmental, Health and Technological Problem Solving (Princeton University Press, 1999) and over 100 technical and refereed publications.
