An intelligent person with passion for excellent, ability to take initiative and also work in group. My field of research involves the application of multiple biological and chemical disciplines including the application of Gas Chromatography, Gas Chromatography-Mass Spectrometer (GC-MS), HPLC, LCMS and NMR in elucidating the modification of plant secondary metabolite signals upon herbivory attack, isolating biotic stress compounds called Herbivory induced plant volatiles (HIPVs), testing HIPVs on parasitoids (using olfactometer and GC-EAD) and quantifying the levels of Semiochemicals emitted.

My research interests includes the isolation, analysis, characterisation, development and application of small lipophilic molecules of biological origin for sustainable pest management, Human health application in Africa and Ghana in particular. Elucidating the modification of plant secondary metabolite signals upon biotic stress and elicitor treatment, and their role in mediating aboveground and belowground pest/host, host/host interactions via chemical communication
