Thomas O’Halloran is an expert on how living cells sense, regulate and manage metals such as iron, zinc and copper. In addition to showing that changes in the levels of some metals within cells may play a role in infectious diseases, cancer, liver disorders and diabetes, he has developed novel drugs for diseases such as Wilson’s disease, fungal infections and cancer. O’Halloran is the Charles E. and Emma H. Morrison Professor in Chemistry and Molecular Biosciences in the Weinberg College of Arts and Sciences and a professor in the department of medicine, division of hematology and oncology in the Feinberg School of Medicine. He is the founding director of the Chemistry of Life Processes Institute (CLP), director of the Quantitative Bio-element Imaging Center and director of the Center for Developmental Therapeutics. O’Halloran is the principal investigator of the Chicago Region Physical Science-Oncology Center (CR-PSOC), a partnership between CLP and the Robert H. Lurie Comprehensive Cancer Center of Northwestern University that unites physical scientists and cancer researchers from Northwestern, the University of Chicago and the University of Illinois at Chicago.
