Dr. Yi Chao is a Principal Scientist at Remote Sensing Solutions, Inc. He received both the M.A. and Ph.D. degrees in Atmospheric and Oceanic Sciences from Princeton University, and the B.S. degree from University of Science and Technology of China.

Since joining RSS, Dr. Chao has continued his development of data assimilation and forecasting capabilities within the Regional Ocean Modeling System (ROMS). Both the in situ and remotely sensed (from both land and satellite platforms) data can be assimilated into ROMS through a multi-scale 3-dimensional variational method in order to enable hindcast, nowcast, and forecast. He has served as the Principal Investigator (PI) for several projects, funded by NASA, NOAA and Office of Naval Research (ONR), to implement the ROMS data assimilation and forecasting system off the coast of California and Alaska as well as in the Gulf of Mexico.

Dr. Chao is currently developing a ROMS data assimilation and forecasting system to support the NASA SPURS (Salinity Processes in the Upper Ocean Regional Study) field experiment planned during 2012 – 2013. He is also supporting a number of JPL projects including Aquarius, Integrated Ocean Observing System (IOOS), Surface Water and Ocean Topography (SWOT).

Prior to joining RSS, Dr. Chao was a Principal Scientist at NASA Jet Propulsion Laboratory, where he was involved in numerous ocean remote-sensing and science projects. He was the Project Scientist for the Aquarius project developing the first NASA satellite mission to measure ocean salinity from space. He also took several management positions at JPL ranging from Group Supervisor to Section Manager.

Dr. Chao was also a PI funded by ONR to have successfully developed, deployed and recovered the first unmanned underwater vehicle (UUV) that is completely powered by renewable energy using the ocean temperature difference. He is currently exploring opportunities to commercialize this technology for underwater monitoring and explorations.
