Christine Floss

Research Associate Professor
Ph.D., Washington University, 1991

Dr. Floss' current research focuses on using trace element (e.g., the rare earth elements) microdistributions to understand the origin and evolution of a variety of differentiated meteorites. Other work includes experimental investigations designed to elucidate the nature of isotopically anomalous material observed in primitive extraterrestrial materials. Some recent publications include:
