    Dr. Wang's research interests include the global carbon cycle, atmospheric chemistry and transport modeling, inverse modeling, satellite observations (including GOSAT and ASCENDS), the global methane cycle, climate trends, and the nitrogen cycle. He has worked as a research scientist (Scientist III) at NASA GSFC since 2012 as an employee of USRA in the GESTAR program. He currently works on projects funded by the NASA MAP and CMS programs involving inverse modeling of atmospheric CO2 (in collaboration with Randy Kawa) and modeling of wetland methane emissions and atmospheric methane and oxidizing capacity (with Bryan Duncan). Models used include GEOS-5, NASA Unified WRF (NU-WRF), and PCTM.  Dr. Wang has conducted simulation experiments for NASA's planned ASCENDS CO2 satellite mission and participated 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. with Honors 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 more than a dozen peer-reviewed scientific articles and several book chapters and has spoken at major scientific conferences.

    Professional Service

    Supervisor and Mentor for GESTAR Fellow, summer 2014, NASA Goddard Space Flight Center. Hired and supervised a graduate student intern from Morgan State University, a historically black institution in Baltimore, MD. Gave him background information on my research topic (inverse modeling of atmospheric CO2) and assigned tasks, helped him learn new skills, introduced him to other scientists and work that goes on at Goddard, and helped him connect his internship work to his dissertation.
