Dr. Bryan Mackenzie
Hello, I'm Bryan Mackenzie. I serve as Academic Director of the SMP in physiology. I am the course director for Interprofessional Education in the fall semester, and for Statistics & Experimental Design in the spring semester. I also teach in Graduate Medical Physiology. I actively serve as an adviser to students in the SMP.
My research program explores the molecular physiology of iron transport, absorption, and homeostasis. Iron metabolism is of major public-health significance because of the huge worldwide prevalence of iron-deficiency anemia, and also common hereditary disorders that lead to iron overload and consequent organ damage. My lab focuses on the mechanisms and structure–function of the iron transporters divalent metal-ion transporter-1 (DMT1)—responsible for cellular iron uptake in the intestine, erythroid precursor cells, and many other cell types—and ferroportin, a cellular iron exporter that delivers iron to the blood plasma from enterocytes and macrophages. Approaches in my lab include functional assays in RNA-injected Xenopus oocytes expressing iron transporters, and iron absorption and homeostasis in genetically modified mouse models.

Admissions | Professional Development
Hello! I am Katie Hobbing. I am an assistant professor of pharmacology and systems physiology. I serve as Associate Director of the SMP in physiology, for which my two major roles are to serve as chair of the admissions committee and to oversee professional development of students within the program. I am course director of the fall course Professional Development.
Dr. Roger T. Worrell
Capstone | Faculty Mentoring
Hello, I am Roger Worrell, and I serve as Associate Director of the SMP in physiology. I am also the capstone course director, and facilitate the faculty mentoring program. My research expertise centers around epithelial ion transport in health and disease, with primary interest in intestinal transport and its relation to microbial niche development and maintenance, as well as interest in renal transport mechanisms. Research methods employed in these areas include cellular, cultured organoid, organ, and whole animal levels. Focus is both on mechanisms and regulation in health as well as in disease states. Disease states include but are not limited to; Cystic Fibrosis, hypertension, endocrine disorders, hepatic encephalopathy, and diarrhea (C. difficile) and intestinal microbial dysbiosis. Professionally, I have been actively involved in the American Physiological Society (APS) since my graduate school days and have been an active member of The Ohio Physiological Society (OPS) since 2001.
Dr. Robert Banks
Founding Director of the SMP
Hello, I'm Bob Banks, Professor Emeritus of Physiology. I have been very involved in UC's Special Master's Program in Physiology since its inception in the fall of 2006. Although I have stepped down as program director,I continue to stay involved in the program and remain committed to helping each of you succeed in achieving your long-term goals. My research expertise is cardiovascular and renal physiology and, although I no longer have an active laboratory, I remain very interested in these fields.
