Organic Chemistry


Research Interest:

My research interests aim at investigating various local medicinal plants with a strong folkloric history of medicinal uses. This involves scanning plant extracts for antimicrobial activity targeting the most troublesome nosocomial opportunistic infectious agents referred to as “ESKAPE” pathogens. These organisms include: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species, and represent the most 3 prominent causes of hospital-acquired infections today. I work in collaboration with Dr. Pascoe (Chemistry) and Dr. Nagy (Biology). Research Poster Presentation
