Actively involved in Cancer and anticancer medicinal plants' research in the Kenyan population. Specifically, involved in identifying and characterizing anticancer medicinal plants for Prostate and Breast Cancer. Also involved in the identification of biomarkers for PCa in the Kenyan (African) population with a view to clearly define the Phenotype/Genotype correlations compared to already published data, with a view to identify new molecular markers in our (Kenyan/African) population with a view to identify new drug targets and elucidate new signalling pathways for biomarkers identified.
