Congratulations to the new Dr. Kalen Rasmussen! Spring of 2023 brought us a great Ph.D. thesis defense from now Dr. Kalen Rasmussen, with a thesis entitled, “Geomicrobial Dynamics and Microbial Metabolism Influence Biomarker Preservation in Actively Lithifying Hydrothermal Environments.” Thanks to the late Dr. Paul Ogg for introducing an undergraduate Chemical and Biological Engineering student to me and my lab. Who knew that Kalen would be around the lab, with many global stops elsewhere, for 10 wonderful years?
