Associate Professor Christopher Hamilton was appointed as a Scialog Fellow in the Signatures of Life in the Universe initiative, a three-year program co-sponsored by the Research Corporation for Science Advancement and the Heising-Simons Foundation, with support from the Kavli Foundation. Signatures of Life in the Universe will bring together scientists from many disciplines to initiate research on the topics of habitability of planets, detection of life beyond Earth, and life in extreme environments on Earth or in Earth’s distant past.
