Dr. Omwoyo is currently a Lecturer in the Department of Mathematics and Physical Sciences, School of Science in Maasai Mara University teaching Inorganic Chemistry courses. He holds a Bachelor of Education Science (Chemistry/Mathematics) and Master of Science in Inorganic Chemistry both from Maseno University. He further undertook a postgraduate training in nanomedicine at the University of Basel, Switzerland which was offered jointly with Novartis Pharmaceutical Research Company during the Next Generations Scientist internship fellowship 2014 sponsored by Novartis Pharma AG. He pursued his Doctor of Philosophy in Chemistry (Nanomedicine) from Jaramogi Oginga Odinga University of Science and Technology in collaboration with the Centre of Excellence in Nanomedicine at the Council for Scientific and Industrial Research, Pretoria, South Africa. His research interests’ areas include but not limited to; nanomedicine which involves encapsulating conventional drugs into selected nanocarriers, characterization, optimization and pre-clinical evaluation of the formulation’s with an aim of improving their efficacy; Synthesis and characterization of nanocomposites for water purification and quantification of endocrine disrupting compounds in water among other research areas.
