Prof. Christine Floss

Christine Floss obtained her Ph.D. in Geochemistry from Washington University (Dept. of Earth and Planetary Sciences) in 1991. Her thesis work focused on understanding the petrogenesis of lunar ferroan anorthosites and an unusual group of enstatite meteorites known as aubrites, through investigation of their trace element microdistributions. She then spent five years working as a research scientist at the Max-Planck-Institut f. Kernphysik in Heidelberg, under the direction of Prof. A. El Goresy, where her research involved experimental and isotopic investigations of kinetic evaporation effects to understand the processes involved in the formation of refractory inclusions and their implications for early solar system evolution. Since 2006 she is Associate Research Professor of Physics.

She is a member of the American Geophysical Union, the Geochemical Society, the Meteoritical Society, Sigma Xi and the Deutsche Mineralogische Gesellschaft. She is also an associate editor for Meteoritics and Planetary Science.

Research Interests

Dr. Floss' research interests focus on using the diversity of extraterrestrial material available for laboratory study (meteorites, cosmic dust) to better understand the origin and evolution of the early solar nebula. Specific areas of current research include:

 

  • experimental and isotopic studies of interplanetary dust particle and primitive chondritic meteorites to understand the distribution and origin of isotopic anomalies observed in these materials

 

  • 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

 

  • studies of 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, aqueous alteration, etc.
