    NEWS:

    --> Congratulations to John Oulton (Ph.D. student in our group) who was awarded a NASA Earth and Space Sciences graduate fellowship! Way to go, Jon!
    --> We are pleased to announce the establishment of CRiO (Collaborative for Research in Origins), funded by The John Templeton Foundation - FfAME origins program.
    --> Jennika Greer defended her M.Sc. thesis and entered the Ph.D. program at University of Chicago's Department of Geophysical Sciences with an NSF Graduate Research Fellowship. We are very proud of you, Jennika! She will be working with Philip Heck on cosmochemical problems.

    RECENT WORK (Check for updates, soon):

  • Thermal effects of impact bombardments on Noachian Mars (EPSL-Frontiers, invited review) Oleg Abramov and I have modeled the thermal fields due to different early impact scenarios of the crust of early Mars
  • Highly siderophile element abundances in Eoarchean komatiite and basalt protoliths We explore (with Elizabeth Frank, and Wolfgang Maier) whether the oldest ultramafic enclaves locked in Eoarchean gneiss complexes could be komatiites, and if they record progressive in-mixing of an HSE rich "Late Veneer"..
  • Correlated chemostratigraphy of Mn-carbonate microbialites (Urkut, Hungary) In association with our close colleagues at the Hungarian Academy of Sciences, in particular Dr. Marta Polgari, we investigate the microbial origins of a peculiar Mn-carbonate ore.

  • Micrometer-scale U-Pb age domains in eucrite zircons, impact re-setting and the thermal history of the HED parent body Although meteoritic zircons are rare, they exist and can inform us about the very early thermal history of asteroids such as 4Vesta.
