Professional Experience

Physical Scientist, AMAD, NERL, U.S. EPA, RTP, NC, 2009 - Present
Lead investigator in the Division for studying and developing methodologies to model aerosol-cloud-climate interaction.  He is principally responsible for developing model parameterizations of cloud-mediated radiative-forcing due to aerosols (i.e., indirect aerosol forcing) in the two-way coupled WRF-CMAQ modeling system. This capability would help in the development of a robust modeling tool that would assist in evolving research and regulatory applications exploring air quality-climate interactions.

STC Senior Scientific Data Analyst, assigned to ASMD, NERL, U.S. EPA, RTP, NC, 2004 - 2009
Principal air quality model evaluator for the Air Quality Forecast (AQF) Team at NOAA/ARL/ASMD.  The AQF system includes NCEP’s mesoscale WRF meteorological model and EPA’s Community Multiscale Air Quality (CMAQ) model.  The whole objectives are to develop and implement plans for operational and diagnostic evaluation of the air quality forecasts for O3 and PM2.5 from the real-time WRF-CMAQ model system being run daily at NCEP.         

UCAR scientist, U.S. Environmental Protection Agency, RTP, NC, 2001 - 2004
Working on the evaluation, test and development of EPA’s Models-3/CMAQ 3-D air quality model for PM2.5 mass, SO42-, NO3-, NH4+, OC, EC, and gas O3, HNO3, NH3, VOC, NOx, and CO over the US; Studying the controlling strategy for PM2.5 and O3 over the US.  Working on the diagnostic evaluation of EPA’s Models-3/CMAQ air quality forecast model for O3 over the Northeastern US.

Research Associate, Duke University, Durham, NC, 1999 - 2001
Working on developing and implementing aerosol modules in regional 3-D air quality models (MAQSIP), and using the newly-developed models to analyze aerosol data from intensive field studies and to evaluate control strategies for ozone and fine particulate matter in the southeastern US. (Supervisor Prof. P.S. Kasibhatla)

Research Assistant, North Carolina State University, Raleigh, NC, 1996 - 1999
Working on the US DOE project entitled “Consequences of Anticipated Greenhouse Warming in the Southeast: Role of cloud-Mediated and Direct Effect of Aerosols”. Responsible for the analysis of optical depth, single scattering albedo, asymmetry factor, upscatter fraction, diffuse to direct ratio at visible wavelengths and aerosol chemistry, size distribution as a function of air mass type, and getting the aerosol columnar size distribution by numerical methods. Measured the CCN and cloud microphysical-chemical properties such as cloud droplet size distribution, and ion concentration.Working on NASA Stratospheric Aerosol and Gas Experiment (SAGE II) project: responsible for algorithm development, microphysics of volcanic aerosols and their effects on climate on the basis of SAGE II satellite measurement. (Supervisor Prof. V.K. Saxena)

Research Assistant, North Carolina State University, Raleigh, NC, 1994 - 1996
Worked on the Aerosol-Cloud-Climate Interaction Project to investigate the effect of aerosols on regional climate and intensively used the SAS statistical model to analyze the climatic data, and study the impact of stratospheric volcanic aerosols on climate in the Southeastern US. (Supervisor Prof. V.K. Saxena)

Environmental Engineer, Xiamen Municipal Research Institute of Environmental Protection, Xiamen EPA, P.R.China, 1988 - 1994
Monitored air pollution by measuring NOx, SO2, TSP, aerosols, O3, acid rain, and dry deposition. Monitored, calculated and assessed the emission strength from the industrial pollution sources, and used a dispersion model to predict the impact of point sources, line sources and area sources of pollution on the environment. Principal investigator for a research project entitled “Investigation about the current situation, sources and causes of acid rain in the oceanic environment of Xiamen Island”

Research Assistant, Environmental Science Center, Peking University, China, 1985 - 1988
Responsible for measuring and analyzing the atmospheric pollutants such as organic acids, NOx, SO2, aerosols, O3, acid rain, and dry deposition in Beijing and in Southern China.
