Prof Nicholas Kamindu Gikonyo
Position: Associate Professor
As an Associate Professor in the School of Pharmacy at Kenyatta University (KU), my expertise is in teaching, research and innovation in the areas of Pharmacognosy, Complementary and Alternative Medicine, Nutrition in therapy and Chemical Ecology. I am the founding Chairman of the department of Pharmacy, Complementary and Alternative Medicine (PCAM) at KU. I spearheaded the development of the curriculum for the Pharmacy degree programme at KU which I anchored on a 5 Year Strategic Plan. I was the founding chairman of the KU Ethics Review Committee and a board member of the KU Research Review and Advisory Board (URRAB), Confucius Institute and KU Funeral Home. Currently, am the Director of KU Funeral Home and Board Chairman of the Chandaria Business Innovation and Incubation Centre (CBIIC) at KU. I am the Deputy Editor of the Kenya National R&D Journal and an Editor of the East and Central Africa Medical Journal. In addition to publishing several scientific papers in peer reviewed journals, I have one Patent granted by KIPI. My current funded project as PI is valued at about KSh.70 million titled “National Phytotherapeutics Research, Upscaling and Quality Assurance Centre”.
My passion is service to humanity through developing affordable, environment friendly solutions to health problems.
