Alex Kimathi is a Research Scientist at KMFRI with wide knowledge on marine plant ecology. Currently attached to the Mariculture Department under the Aquaculture Division, he is charged with coordination and supervision of seaweed mariculture research interventions.

Alex is among the leading scientists in the introduction of seaweed cultivation in Kenya and the implementation of Kenya Coastal Development Projects, specifically the upscaling of commercial seaweed farming in villages on the southern coast of Kenya between 2009 and 2015. His pioneering work has contributed significantly to livelihood diversification and blue economy development for coastal communities.

Being a trained SCUBA diver and an active member of the Seagrass Net Group in KMFRI, Alex also participates in seagrass research activities including habitat mapping and monitoring. He is also a member of the Scientific Monitoring and Evaluation Committee in KMFRI, contributing to the Institute's research quality assurance and strategic oversight.

Research Interests
Seaweed Mariculture Systems – Research to enhance local and regional biomass production through improved cultivation techniques and farming systems.
Policy Development – Development of policy briefs on mariculture-related issues (culture systems, value addition, post-harvest) to offer policy direction for a sustainable mariculture industry.
Seagrass Ecosystem Research – Habitat mapping and monitoring to understand seagrass dynamics and inform conservation strategies.
Growth Rate Studies – Published research on growth rates of Eucheuma denticulatum and Kappaphycus alvarezii cultured using modified off-bottom and floating raft techniques in the Kenyan coast (Western Indian Ocean Journal of Marine Science 2018).
Alex Kimathi's pioneering research and coordination in seaweed mariculture at KMFRI strengthens the Institute's capacity to develop sustainable seaweed production systems, enhance blue economy opportunities for coastal communities, and provide policy-relevant science for the growth of Kenya's mariculture industry.
