Profile Summary

Dr. John W. Birks is co-founder and Chief Scientist at the new startup company Liquen Technologies. He previously co-founded the company 2B Technologies where he developed more than 20 air pollution monitoring instruments. John is Professor Emeritus of Chemistry and Biochemistry and Fellow Emeritus of the Cooperative Institute for Research in Environmental Sciences (CIRES) of the University of Colorado Boulder. John earned a B.S. degree in Chemistry with High Honors at the University of Arkansas, Fayetteville in 1968 and a Ph.D. in Chemistry at the University of California, Berkeley in 1974 under the direction of Professor Harold Johnston. Dr. Birks began his academic career at the University of Illinois at Urbana-Champaign in 1974 where he established a research group in atmospheric chemistry investigating mechanisms of ozone depletion in the stratosphere. In 1977, Prof. Birks moved his research group to the University of Colorado where he could collaborate more closely with CIRES, NCAR and NOAA scientists. Prof. Birks is best known for quantifying the rates of several chemical reactions key to understanding ozone depletion in the Antarctic “ozone hole”, his seminal work in 1981/82 with Paul Crutzen (Nobel Laureate, 1995) in developing the “nuclear winter” theory, and his invention, development and commercialization of miniaturized instruments for air pollution measurements. Prof. Birks has published more than 140 scientific papers, edited 3 books and holds 14 US patents. He has supervised the research of 39 Ph.D. students and 9 M.S. students. His awards include Alfred P. Sloan and John Simon Guggenheim Fellowships, the Thomas Jefferson Award of the University of Colorado, the Colorado Section Award of the American Chemical Society, the Leo Szilard Award for Physics in the Public Interest of the American Physical Society, the American Chemical Society Award for Creative Advances in Environmental Science and Technology, the Hazel Barnes Prize (highest faculty award of the University of Colorado), the 2019 Haagen-Smit Clean Air Award of the California Air Resources Board, and the Future of Life Award. In 2009, Dr. Birks founded the Global Ozone Project or "GO3 Project" where middle and high school students around the world measure ozone and meteorological parameters outside their schools and upload their data to the GO3 database for display on Google Earth. More than 100 schools, including 35 international schools, have participated in the GO3 Project, uploading and sharing more than 12 million ozone measurements. The GO3 Project, which involved only fixed-based measurements of ozone, evolved into AQTreks, a mobile monitoring program in which students and other citizen scientists make measurements of CO, CO and particulate matter (PM1, PM2.5, PM10) along treks of their own design. To date, approximately 8,000 students have participated in AQTreks at more than 150 schools throughout the U.S. Wikipedia: https://en.wikipedia.org/wiki/John_W._Birks
