Global carbon cycle (including CO2 and methane), atmospheric chemistry and transport modeling, inverse modeling, satellite observations (including GOSAT, OCO-2, and ASCENDS), climate trends, and the nitrogen cycle.


Dr. Wang joined GESTAR/USRA in 2012 and has worked at NASA GSFC on inverse modeling of atmospheric CO2 in collaboration with Randy Kawa and on modeling of atmospheric methane, carbon monoxide, and oxidizing capacity with Bryan Duncan. He is working on projects in NASA’s Modeling, Analysis, and Prediction Program and Carbon Monitoring System Program. He has been actively involved in NASA's planned ASCENDS CO2 satellite mission, conducting simulation experiments and participating in the writing of the mission white paper.

He received a Ph.D. in atmospheric science from the Dept. of Earth and Planetary Sciences at Harvard University in 2003, and a B.S. in Biological Sciences from Stanford University in 1995. He conducted his doctoral research on modeling recent atmospheric methane trends under the advisorship of Michael McElroy.

After finishing his Ph.D., he worked as a scientist for the non-profit organization Environmental Defense Fund in New York for 7 years. His work involved primarily educating policymakers and the public on scientific and policy aspects of global warming and air quality. He also maintained his research activities, conducting modeling of atmospheric chemistry, climate change, and anthropogenic perturbation of the nitrogen cycle.

Having decided to get back into full-time scientific research, he won an NRC Senior Research Associateship award that allowed him to work at the NOAA Air Resources Laboratory in Silver Spring, MD for a year. There he analyzed tropical stratospheric and tropospheric climate trends using radiosonde observations and climate model simulations in collaboration with Dian Seidel and Melissa Free.

Dr. Wang has published a dozen peer-reviewed scientific articles and several book chapters and has spoken at major scientific conferences.

Dr. Wang has supervised and mentored a graduate student GESTAR Fellow from Morgan State University.
