Brief Bio

Dr. Paul A. Newman is the Chief Scientist for Earth Sciences at NASA's Goddard Space Flight Center in the Earth Sciences Division (Code 610), and a Senior Fellow for Goddard. Dr. Newman was the co-chair of the Scientific Assessment Panel (SAP) to the Montreal Protocol (2007-2023). The SAP is charged with drafting reports on the state of ozone depletion every four years. The most current report is "The Scientifc Assessment of Ozone Depletion: 2022." Dr. Newman is principally involved in the analysis of stratospheric meteorological and trace gas observations.


Dr. Newman is a Seattle native who graduated from O'Dea High School in 1974. He attended Seattle University and graduated in 1978 with a BS in Physics and a minor in mathematics. He completed his doctorate in physics at Iowa State University in 1984. From 1984 to 1986, Dr. Newman was a National Research Council fellow, worked for Applied Research Corporation from 1986 to 1989, and the Universities Space Research Associates from 1989 to 1990. He has been with NASA since 1990.


Dr. Newman's principal area of research is atmospheric dynamics and chemistry. He has participated in numerous aircraft field campaigns with his NASA, NOAA, and University colleagues, and actively researches dynamical and chemical processes.
