Dr. Dennis Maina is a Horticulturist, Applied Nanotechnologist and Lecturer. Dennis has teaching, research, outreach, industrial production and management skills acquired from the varied working experiences. Also, a trainer of trainers on Integrated Pest management, Organic Farming, Sustainable/Conservation Agriculture, Good Agricultural Practices, Greenhouse Farming, Food Safety Management System and Safe Use of Agrochemicals. My research skills are in application of organic nanopolymers and use of biological agents in solving agricultural challenges to increase food quality and quantity with maximum environmental care. I am a member of the Horticulture Association of Kenya.
