He has a vast experience in aquatic sciences and environmental toxicology. He is currently pursuing his PhD in Limnology at Kisii University. He holds an MSc Degree in Fisheries and Aquatic Science (Aquatic Science Option) and a BSc Degree in Fisheries and Aquatic Science. He is a trained Environmental Impact Assessment (EIA) and Environmental Audit (EA) Expert. He is trained as an Integrity Assurance Officer (IAO) with the Ethics and Anti-Corruption Commission (EACC), Kenya and is a KMFRI Management appointee to Baringo Anti-corruption Committee where he serves as the Secretary. He also serves in the KMFRI Technical Committee for Freshwater Systems on Engagement with County Governments where he serves as a Liaison Officer for Baringo County.  He is also trained as a Manager (International Diploma in Human Resource Management; and National Diploma in Human Resource Management/Personnel Management). He did a novel/innovative study on “Adding value to our produce” where with his colleagues he formulated the 1^st seaweed bath soap and other products using locally grown seaweeds in the Kenya Coast which has seen KMFRI and other organizations set up a factory to formulate seaweed products at Kibuyuni, South Coast. He has carried out research in environmental Risk Assessments (ERAs) using Chironomus spp. as a test organism and currently he is working on “Bioavailability, bioconcentration and biomagnification of pesticides by aquatic macroinvertebrates of different feeding guilds and fish in estuarine ecosystems along the Kenya Coast”; “Fisheries status of riverine and small water bodies (SWBs) in Lake Baringo Basin (LBB)” among others.  Other research projects he has carried out include National Research Fund (NRF) and National Council of Science Technology and Innovation (NACOSTI). He also volunteers to offer free consultancy services on proposal development (Give back to community) to Community Based Organizations and other organized groups in the country for the purposes of food security and poverty alleviation.  He has published more 18 papers in peer reviewed journals, and has presented over 45 papers in both international and national scientific conferences.
