Dr. Totah obtained her bachelor’s degree in chemistry from Birzeit University in Palestine and her master’s and PhD in medicinal chemistry from the University of Kansas. Dr. Totah is currently an associate professor in the Department of Medicinal Chemistry. Her research is in the area of prescription drug negative side effects especially in the heart, skeletal muscle and bone. She focuses on researching the chemical mechanisms for this toxicity. Her research is important in guiding research towards medicines with fewer side effects and safer use. Research in the Totah lab is broadly centered on drug-endogenous substrate interactions.
