My major research programs are in three broad areas.
AIR QUALITY: Current research: Clean burning biomass stoves. Engineering science, design, and development of fuel-efficient clean-burning low-emission cook stoves for the 3 Billion people on the planet that still use biomass for cooking. We have set up one of the best labs globally for measurement of cook stoves efficiency and emissions. Past research: Indoor Radon modeling and mitigation, indoor air pollutants and transport. Penetration of outdoor airborne pollutants into residential and commercial buildings. Protection of civilian buildings from external and internal airborne agent threats. Rapid real-time interpretation of diverse indoor sensors to provide probabilistic estimates of toxic airborne threat and its evolution.
WATER QUALITY: Current research: Making drinking-quality water from ground water sources contaminated with arsenic, fluoride, and high levels of Total Dissolved Solids (TDS). Engineering science, design and development of technologies for safe drinking water. Past research: affordable and effective removal of pathogens from contaminated water sources for poor communities in poor countries.
A major multi-Campus research program on energy-water that I lead from 2015 onwards is CERC-WET. See: http://cercwet.berkeley.edu
VARIOUS: Computational fluid mechanics and heat transfer, energy efficiency in buildings, life-cycle analysis, environmental analysis applied to relevant problems in the industrial countries and developing countries.
Another major multi-institution program that I lead is the Development Impact Laboratory, or DIL.
