My Riebe, cosmochemistry

I’m a cosmochemist working at the Department of Terrestrial Magnetism, Carnegie Institution for Science, Washington DC. I am primarily interested in early Solar System processes and I spend my days thinking about things related to how/where/when organic matter that we find in some meteorites formed, if irradiation from the early Sun left traces in meteorite components, and how strange meteorites like Almahata Sitta formed. Find out more about me and my research under the tabs at the top of the page.

September 2018 - Department seminar at Lund University, Sweden

I gave the department seminar at the Department of Geology, Lund University, Sweden with the title "Clues to the formation of solar system materials from noble gases and hydrogen". It was so much fun to visit the department where I did my BSc and MSc!

September 2018 - EPSC

I gave a talk at EPSC in Berlin, presenting my work on "D/H and microstructure of irradiated organic dust analogs". The abstract is available here.

August 2018 - Goldschmidt

I attended the Goldschmidt conference in Boston and presented a poster on my work on what noble gases and presolar SiC grains in the very special meteorite Tagish Lake can tell us about aqueous alteration. The abstract is available here . Click on the poster for a high resolution pdf.

July 2018 - Invited talk at NASA Ames, CA

I visited my collaborators Scott Sandford and Michel Nuevo at NASA Ames to discuss our project on the formation of extraterrestrial organic matter and to give a talk.

March 2018 - LPSC

I presented a poster at LPSC, The Woodlands, Texas, on noble gases in a new type of Almahata Sitta sample with the title "Noble Gases and Cosmic Ray Exposure Ages of the Newly Discovered Almahata Sitta C1+Ureilite Breccia Sample". You can find the abstract here and look at the poster below.

July 2017 - MetSoc

I attended the 80th Annual Meeting of the Meteoritical Society in Santa Fe, New Mexico and presented my research on the effects of atmospheric heating on organic matter in Interplanetary Dust Particles. The Meteoritical Society supported my travel with an award for Early Career Scientist.
