Ivan Clark has been a NASA researcher for over 50 years with focus areas including infrared detectors, materials processing, fluid dynamics of crystal and device growth, lidars and atmospheric environment sensing, and atmospheric hazard impacts to aviation. He has been a Co-Investigator (CoI) for the Long Duration Exposure Facility (LDEF) Pyroelectric Infrared Detectors Experiment, Co-I for the Materials Processing in Space PbSnTe Melt Growth Experiment, and Principal Investigator (PI) or Co-I for multiple Microgravity Sciences research efforts on phase transformation and multi-phase transport. He has been Agency lead for Electronic Materials Integrated Electro-Optic Devices technology, Turbulence Detection lead for Weather Accident Prevention Project that resulted in Enhanced Turbulence Mode for commercial airborne weather radars, Lidar and Electro-Optic Sensors Lead for Integrated Intelligent Flight Deck Project and Atmospheric Environment Hazards Prevention Project. He was SubTopic Manager for the SBIR effort that led to the commercialization of the FLUENT CFD. IRAD PI research includes Active Optical Relative Positioning for UAV as well as Optical Air Data Systems for controlled aerodynamic Mars EDL. He has been COR and mentor for multiple SBIR efforts including: lidars and lidar components, lidar imaging, forward-looking Optical Air Data Systems, and high-resolution nowcasting/forecasting weather systems for UAM/AAM operations.

Academics: BS Physics (VPI&SU), MS Materials Science (GWU), and PhD Materials Science and Eng (UVA)
