About

Dr. Ronald Daly is a Senior Professional Staff member at The Johns Hopkins University Applied Physics Laboratory in the United States. His research focuses on asteroid material properties, impact dynamics, and the characterization of organic-rich regions in celestial bodies. Recent publications include studies on the ejecta dynamics of Dimorphos and the implications of asteroid impacts for astrobiology.
