Biography: Dr. Marc Fries
Dr. Marc Fries is a Research Scientist at the Planetary Science Institute located in Tucson, Arizona.

Dr. Fries is Raman spectroscopist, which studies the interaction between matter and radiated energy and has extensive experience in the mineralogy and petrography of carbonaceous materials. The central theme of his current research is studying carbon in geological systems, namely studying the formation and petrologic/chemical history of carbonaceous species as a means of describing the history of the parent rock. This course of research includes study of reduced carbon phases in meteorites, analysis of fluid inclusions in various rock types, analysis of carbon structure in ancient microfossils as well as shock metamorphism of diamond and other high-P,T phases in impact materials. Dr. Fries served as an investigator on the Stardust Preliminary Examination Team interpreting the formation and metamorphic history of carbonaceous materials in samples from the comet 81P/Wild 2. His interests also include developing new methods for ascertaining the biogenic vs. abiogenic origin of condensed carbon species as well as methods for quantitative description of the formation and alteration histories of reduced carbon phases in planetary, asteroidal and cometary settings. Dr. Fries also studies meteorite fall dynamics and new methods for finding freshly fallen meteorites such as the use of Doppler weather radar.

He received his Ph.D. from the University of Alabama in Birmingham in Materials Science.
