I happened upon teaching and research by accident. I had gone to the University of California, Santa Barbara, for a MS in chemical engineering, with the intention of returning to my engineering job at Larsen & Toubro, Bombay. Research hooked me, however, and I stayed on for a PhD, and, in fact, never left academia after that. Indeed, my world has remained virtually unchanged over the last three decades, continuing to work on applying the principles of kinetics, catalysis, and reaction engineering to energy challenges, surrounded by bright young people eager to do the same. Sustainable and clean energy constitute some of the biggest challenges facing humanity. While the long-term solution is renewable energy, much can be accomplished in the coming decades simply by improving energy efficiency. Fuel cells and hydrogen represent some of the most promising clean energy technology in this regard, which we have been pursuing since the early nineties. In addition, we have pursued renewable fuels, including ethanol and ethanol-derived ethers, for blending with gasoline. Further, we have developed novel catalysts and approaches to investigate kinetics of reaction networks.

Spotlight On: Current Research
Fuel cells are amazing devices, with no moving parts, that produce electric power silently and directly from a fuel. The current limitations of PEM fuel cells are high cost, inadequate durability, and sensitivity to contaminants in hydrogen.
