Evaluation and Intercomparison of Small Uncrewed Aircraft Systems Used for Atmospheric Research
Dr. Elizabeth A. Pillar-Little
Former Research Scientist
Elizabeth Pillar-Little was the Assistant Director for the former Center for Autonomous Sensing and Sampling at the University of Oklahoma, where she was responsible for coordinating the field deployments of RPAS teams from both an operational and scientific perspective. She also ensured the continuity of day-to-day center business and enjoyed spearheading outreach and science communication activities on behalf of the center. She was also appointed as a research scientist in the School of Meteorology and led the atmospheric chemistry research nucleus of CASS. Dr. Pillar-Little’s research interests were broadly centered around atmospheric and environmental chemistry, but she is very passionate about atmospheric composition, aerosol optical properties and composition, and the interplay between aerosols and convection initiation.

Ph.D. Graduate
Dr. Antonio R. Segales
Research Engineer
My research centers around developing small unmanned aircraft systems for adaptive atmospheric sampling which involves CAD modeling, systems optimization, hardware and software integration, and control theory. I have led the design of the CopterSonde series of vehicles, which is used to perfrom controlled and targeted weather sampling at high temporal and spatial resolutions. I am also advising other projects in which sensor integration or new UAS are required.
