David Chassin is the president of Eudoxys Sciences after forming it on September 3rd 2024.

David Chassin recently retired as group manager, lead scientist, and a principal investigator in the Grid Integration Systems and Mobility (GISMo) group at SLAC National Accelerator Laboratory, which is operated by Stanford University. He managed research and development activities in renewable energy and grid integration systems. Before joining SLAC, he was a staff scientist at Pacific Northwest National Laboratory (PNNL) where he worked since 1992. He led the development of building energy modeling, control and diagnostic systems, including Softdesk Energy and DOE’s Whole Building Diagnostician. He designed the Olympic Peninsula and Northeast Columbus retail real-time pricing systems. He managed the development of GridLAB-D™, an open source smart grid simulation built by PNNL for the US Department of Energy.

Dr. Chassin was a member of the Western Electricity Coordinating Council’s (WECC) Market Integration Committee and the North American Electricity Reliability Council (NERC) Load Modeling Task Force. He serves on the NERC Load Modeling Work Group contributing to the development of composite load model data for North American utilities and reliability coordinators. His current research is focused on the control and dispatch of fast-acting demand response, retail real-time demand dispatch using prices, and transactive control theory. He has been awarded 21 US patents in building energy system diagnostics, grid-friendly appliance controls, and transactive control systems, and has published over 150 articles, papers and technical reports. He is a senior member of the IEEE.
