 Hanwant B. Singh received his Ph. D. from the University of Pittsburgh (1972) and B. Tech from the Indian Institute of Technology Delhi (1968), both in Chemical Engineering. He has studied the composition and chemistry of the atmosphere for the past 30 years and has published more than 220 scientific papers (h-index: 84; 21000 citations) and one textbook in this area. His primary research goal has been to better understand the impact of human activities on the chemistry and climate of the earth's atmosphere through direct observations and data analysis. He has designed and led major international field campaigns towards this goal. He led a group of atmospheric scientists at the NASA Ames Research Center and is a former Director of Atmospheric Chemistry laboratory at SRI, formerly Stanford Research Institute. He is the recipient of the HJ Allen Prize for best paper, Frank A. Chambers Award for "outstanding achievement in the art and science of air pollution," three NASA Exceptional Leadership/Scientific Achievement Medals (1998, 2005, 2009) and most recently NASA’s highest honor “The Distinguished Service Medal”.  He is a Fellow of the American Geophysical Union and the World Innovative Foundation and a Distinguished Alumnus of the Indian Institute of Technology, Delhi, and the University of Pittsburgh School of Engineering. For 25 years (1992-2017) he was the Editor-in-Chief of the international journal Atmospheric Environment.  He retired in 2018 and is presently active as an “Ames Associate”.

Scientific Contributions:
Proposed and led major atmospheric field experiments.  Developed highly sensitive instrumentation and provided key measurements in the atmosphere and the oceans using surface and airborne platforms. Following are examples of contributions (made with colleagues) that have had a significant impact:
- First to detect and measure phosgene in the atmosphere.
- First to demonstrate that atmospheric carbon tetrachloride was of man-made origin, now a widely accepted view.
- First to propose and apply the concept of using methyl chloroform as an indicator of OH radicals to study global oxidation.
- First to discover that a large background of PAN was present in the global troposphere; developed new instrumentation and performed field studies to demonstrate its important role in ozone chemistry.
- Provided the first global measurement of important oxygenated organic species (e. g. acetone, methanol) and proposed a new source of HOx radicals from oxygenated species.
- Developed sensitive methods to explore chlorine atom chemistry in the troposphere.
Over 220 scientific publications in major scientific journals (h-index: 84; 21000 citations)
Book chapters
One textbook titled "Composition, Chemistry and Climate of the Atmosphere"
