Amit K. Tiwari

Assistant Professor


Dr. Tiwari is an Assistant Professor in the College of Pharmacy and Pharmaceutical Sciences, University of Toledo. By using genomic analysis and pharmacokinetic/pharmacodynamics approaches, Dr. Tiwari intends to probe molecular and signaling pathways at the systems-level and build quantitative models to translate these findings in improving and developing new and safer anticancer drugs. Additionally, Dr. Tiwari’s work has established novel ways to reverse drug resistance and to improve cancer chemotherapeutics. Dr. Tiwari has authored over 40 peer-reviewed articles. He is an editor and editorial board member of number of journals and is an ad hoc reviewer of over 50 journals.


Area of Interest

Dr. Tiwari’s Cancer Pharmacology and Systems Therapeutics lab is focused to not only finding a cure for cancer but also on bridging Cancer Health Disparity among segments of the population. Currently, his lab’s efforts are directed in the following key areas:
Multidrug Resistance in Cancer
Targeting Factors Associated with Cancer Health Disparity
Drug Discovery & Experimental Therapeutics
