David Chassin is the founder and president of Eudoxys Sciences LLC.

David Chassin recently retired as group manager, chief scientist, and 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.
