Catherine Koebel received her undergraduate degree from the College of William and Mary, where she majored in Biology. She received her PhD in Immunology from Washington University in St. Louis and worked at a start up biotechnology company. Her research in the field of tumor immunology was the first to show that the adaptive immune system can keep tumors in an occult state, virtually undetectable unless immune pressure is removed. This finding helped further understanding of how immune pressure shapes tumor development. She is teaching BIOL 310 Molecular Cell Biology this semester.
