• Bachelor of Science Forestry (Second class Upper division)- Moi University, Chepkoilel Campus
• My main research activities revolve around eco-physiological response of ecosystems to disturbance and stress focussing on physiological, morphological and anatomical aspects of flora and fauna but also with a keen interest on ecological restoration.

Participation in research groups and projects

• Currently working with Coast Development Authority under the Integrated Shoreline and Mangrove Ecosystem Management (ISMEM) component of the Kenya Climate Change Adaptation Project (KCCAP)

• I am one of the key implementers of the recently funded Trans-Coast project which will look at Transboundary coastal processes and human resource utilisation patterns as a basis for Kenya-Tanzania conservation area initiative boundary

• I am a member of the support expert group preparing the State of the Coast report for

• So far supervised one master student from the University of Ghent, Belgium to a successful completion and currently working with one student from VUB on spatial analysis of erosion potential of transboundary River Umba

• I have obtained grants from various institutions to support my research work including: Fonds David et Alice Van Buuren; Vlaamse Interuniversitaire Raad (VLIR); and MARG II and III from WIOMSA
