Collins is a research scientist at the Kenya Marine and Fisheries Research Institute (KMFRI) and a PhD Fish Biology student at in the University of St. Andrews in Scotland, whose project’s working title is, ‘Inter-annual variability in abundance of key fish and pelagic crustacean species in the Lake Victoria ‘natural laboratory: from ecosystem understanding to fisheries management’ and aims to improve the understanding of ecological dynamics of pelagic species in Lake Victoria, East Africa.. His interdisciplinary research experience covers aquatic ecology, biogeochemical processes, fisheries, water quality assessment, and associated interactive processes driving climate change in marine and freshwater ecosystems. His current work focuses on ecosystem integrity assessment in relation to fish stocks.
