Clayton Memorial Symposium

September 11, 2018

The University of Chicago will be hosting a Symposium on Monday, September 17th and Tuesday, September 18th of 2018 to commemorate the life and legacy of Robert Clayton.  A pioneer in the field of cosmochemistry, Robert Clayton spent over five decades as a member of the Department of Geophysical Sciences, and passed away in December.

The Symposium will be held in the Henry Hinds Laboratory for Geophysical Sciences. Talks will be given in HGS 101, and refreshments in HGS 176.
