I am currently Chair of the Department of Surgery at Mayo Clinic in Rochester and the Program Director of the Center for Individualized Medicine (CIM) Microbiome Program. My career has focused on advancing the care of patients with colorectal cancer, through the advancement of new technologies, standardization, novel clinical trial design, and biologic studies. My long standing research leadership roles have included the Mayo Clinic Cancer Center and the NCI Cooperative Groups: I was Vice Chair of the North Central Cancer Treatment Group and then served as Group Co-Chair of American College of Surgeons Oncology Group. As an individual investigator, I was the national PI and NCI-grant PI for the NIH-funded colon cancer trial and senior author on the international laparoscopic rectal cancer trial. I have been faculty for the AACR/ASCO Methods in Clinical Cancer Research Workshop for a three year term, a member and then chair of two NIH (NCI) study sections including, Subcommittee H (Cooperative Group Study Section), Clinical Oncology (CONC) and a member of the NCI Clinical Trials Advisory Committee.
