I am currently a research meteorologist for National Severe Storm Laboratory (NSSL)/National Oceanic and Atmospheric Administration (NOAA). I am also affiliated with University of Oklahoma (OU) as Research Fellow for the Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO), and as adjunct faculty member for the School of Meteorology (SoM). Before joining NSSL in 2010, I was an employee for OU Center for Analysis and Prediction of Storms (CAPS) for 13 years. I was the main developer of a hybrid ensemble-variational radar data assimilation system (Gao et al, 1999, 2004, 2013, 2016; Gao and Stensrud, 2012, 2014) which has interface with both open-source community Advanced Regional Prediction System (ARPS), and Weather Research & Forecasting model (WRF).

Unlike many other meteorologists here who love to chase storms or even tornadoes, I would rather stay indoors and play with complex formulae and computers. I consider myself as a part-time scientist who conducts scientific research and part-time software engineer who develops data assimilation programs for numerical weather prediction models. You are welcome to view my NSSL website which mainly includes my biographical sketch, full CV, list of formal publications, and Google Scholar page.
