Isaac comes from Kenya, where he got his Masters and Bachelor of Environmental Sciences from Kenyatta University, Nairobi, Kenya. Now, he is studying for a PhD in the School of Geographical Sciences at the University of Bristol, UK. His primary supervisor (advisor) is Katerina Michaelides and he is co-supervised by Michael Singer at Cardiff University.

Isaac is currently working in DOWN2EARTH on the impacts of climate and climate change on water and vegetation dynamics in Horn of African drylands. He aims to characterise changes in land surface properties in Horn of Africa at synoptic, regional and local scales using a combination of satellite remote sensing and soil-based metrics. Isaac aims to provide vegetation as well as soil moisture dynamics in response to climatic and other hydrological drivers. He has broad range of interests ranging from drought, geostatistics, remote sensing and more broadly data-visualisation and in future thinks of coupling human-physical systems.
