CPR Initiative Board Member
Atmospheric Scientist and Entrepreneur
John is an atmospheric scientist and entrepreneur, and the former Chief Scientist at 2B Technologies — a company he co-founded in 1998 that develops and manufactures new products for air quality measurements.
John is also Professor Emeritus of the University of Colorado where he and his graduate students carried out research in atmospheric chemistry for 25 years. He is best known for his work in quantifying the rates of chemical reactions that cause the Antarctic Ozone Hole, his co-development of the “nuclear winter” theory with Paul Crutzen in 1982, and the development of miniaturized instruments for air pollution measurements.
John’s current research is focused on the use of low-cost sensors for mobile monitoring of air pollutants in cities, an outgrowth of the AQTreks educational outreach programs his company implemented in several hundred schools around the US. John splits his time between Ramona, California and Boulder, Colorado.
