Dr. Tsengdar Lee manages the High-End Computing Program from NASA Headquarters. He is responsible for maintaining the high-end computing capability to support the agency's aeronautics research, human exploration, scientific discovery, and space operations missions. Lee is also the manager of the NASA Weather Data Analysis Program, focusing on the transition of research results into the operational forecast centers and the acceleration of operational use of research data. Two major activities include the multi-agency Joint Center for Satellite Data Assimilation and the Short-term Prediction Research and Transition Center.

Lee joined NASA in 2001 as the High-End Computing Program Manager for the Earth Science Enterprise. He was responsible for the Earth science computational modeling needs, primarily focusing on weather and climate modeling. Between 2002 and 2006, Lee also managed the Earth Science Global Modeling Program. He funded research efforts to study the global climate change, weather forecasting, and hurricane prediction problems.

Prior to 2001, Lee held positions as Senior Technical Advisor with Northrop Grumman Information Technology and Senior Staff Engineer with Litton PRC. He worked on the Advanced Weather Information Processing System (AWIPS) project for the National Weather Service. He was responsible for the rapid development, integration, and commercialization of the AWIPS client-server system. Lee also was a principal engineer on the effort to develop the AWIPS network monitoring and control system.

He was a Research Scientist and worked on the dispersion problem of bio-chemical agents during his short tenure with the Science Applications International Corporation between 1994 and 1996.

Lee received two graduate degrees from Colorado State University, a PhD in Atmospheric Science in 1992 and an MS in Civil Engineering in 1988. Trained as a short-term weather modeler, his work focused on the integration of weather and ancillary geographical information data into weather models to produce reliable forecasts. His research pioneered the modeling of land surface hydrology’s impact on weather forecasting.
