ARES William Louis Stefanov


William Stefanov is the technical lead of the Earth Science and Remote Sensing (ESRS) Unit within the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center. He is the Associate International Space Station (ISS) Program Scientist for Earth Observations, and the NASA Applied Sciences Disaster Program Disaster Coordinator for Johnson. Stefanov currently serves as the Principal Investigator of the ISS Crew Earth Observations Facility and oversees ESRS support to the ISS Program for NASA ISS remote sensing activities and disaster response. Stefanov’s work supports the advancement of utilization of the ISS for remote sensing and disaster response, as well as astronaut training in scientific observation and data collection in support of future human space exploration missions.
