Ian Hurley is finishing up his B.A. in Biology and Spanish at Kalamazoo College. He has a passion for health care and is looking to go to medical school to become a surgeon. In the Holodick lab, Ian is investigating the impact of estrogen on aging B-1 cells by comparing gene expression of aged/young B-1 cells (extracted from mice) with and without estrogen receptors. This research is being done to support the general investigation of the role of B-1 cells in healthy aging and disease. Outside the lab, Ian enjoys running, making time for family, and camping/backpacking

Peter Ewing earned his B.A in Psychology and Medieval Studies from the University of California, Davis. From there, Peter joined the workforce for several years serving as a Public Safety Dispatcher before returning to school to pursue interests in biomedical research and medicine. He earned a Master of Science in Biology from California State University, Los Angeles in 2016, completing a thesis on the knockout of a heme utilization cluster in a hypervirulent bacterial strain. Peter then matriculated to Western Michigan University Homer Stryker M.D. School of Medicine. As a medical student, Peter has had a passion for Psychiatry, with clinical interests in general inpatient treatment, addiction, new and novel treatment modalities and the efficacious use of medication-assisted psychotherapy. Peter joined the Holodick lab in early 2000 and has been working on projects exploring the role of IgM in selection of the murine B-1a cell repertoire with age. Outside of the lab, Peter enjoys hiking, travel, and his cats.
