Dr. Ibrahim’s research interests are in the area of pharmacognosy with main focus of studying complex natural products chemistry of leads acting on anticancer, MRSA, HCV, malaria, and depression disorders. He has blended the chemistry and biology of numerous natural products to generate several milestones in the field of natural products including the importance of endangered plants in natural products drug discovery (PNAS 110, 16832-16837, featured article in “University of Washington’s Conservation Magazine” September 13, 2013, by Roberta Kwok; featured article recommended for teaching in “F1000Prime” October 11, 2013. by David Triggle), and the discovery and characterization of the plantanoside leads for the control of drug-resistant infectious diseases (patent US8633166B2).
