Is a seasoned academic and researcher in the field of Organic Chemistry (Natural products) with over 13 years of experience in teaching, research, and extension services.
He holds a Ph.D. and Masters degree in Organic Chemistry and I have made significant contributions to both theoretical and applied aspects of the discipline. My areas of expertise include natural product chemistry, phytochemistry, synthetic organic methodologies, green chemistry, plant metabolomics, nanotechnology, and medicinal chemistry.
He has authored and co-authored more than 20 peer-reviewed research publications in reputable international journals. His work continues to influence ongoing studies in organic synthesis and its application in pharmaceuticals and environmental sustainability.
He is actively involved in postgraduate mentorship and am currently supervising several Master’s and Ph.D. candidates, contributing to the development of the next generation of chemists and researchers. I engage in multidisciplinary research and community outreach programs that promote the application of organic chemistry in real-world challenges, including drug discovery, agricultural development, and environmental conservation.
