About the Lab

The Geomicrobial Physiology lab at the University of Colorado Boulder started in the Fall of 2016 and is focused on studying the physiological drivers of geochemical fingerprints of microbial metabolism, particularly isotopic effects and molecular markers. The lab is part of the newly expanding Geobiology program at CU Boulder, that also comprises Alexis Templeton’s, Julio Sepulveda’s, Boswell Wing’s and Steve Mojzsis’ groups, and has close ties with the Institute of Arctic and Alpine Research (INSTAAR) and the Biofrontiers Institute. Please note that this website is still under construction and more information will follow soon. In the meantime, please contact me at sebastian.kopf (at) colorado.edu about upcoming research opportunities at CU Boulder.
