Professor Floss focuses on using the diversity of extraterrestrial material, such as meteorites and cosmic dust, available for laboratory study to better understand the origin and evolution of the early solar nebula.
Floss's specific areas of current research include:
- Identification of circumstellar silicate and oxide grains to understand the conditions of formation in their stellar sources, as well as their survival in solar system materials.
- Experimental and isotopic studies of interplanetary dust particles and primitive chondritic meteorites to understand the distribution and origin of isotopic anomalies observed in these materials.
- Studies of the trace element distributions in individual minerals of meteorites, lunar samples and terrestrial rocks, to understand their petrogenesis, as well as secondary effects occurring on their parent bodies (thermal metamorphism, alteration, etc).
