Abraham Chirchir is a Graduate Engineer and academic researcher in the School of Engineering at Moi University, specializing in sustainable water treatment technologies. Holding an MSc in Chemical Engineering (2018) with a thesis on biogas production from distillery wastewater over immobilized methanogenic consortia and a BTech in Chemical & Process Engineering (2004), he spearheads cutting-edge research in environmental remediation. His current work focuses on “eliminating residual antibiotics and antibiotic-resistant microbes from wastewater via solar-activated, folic acid-modified photocatalysts, as well as advancing water desalination in arid regions through photovoltaic-batch reverse osmosis systems, a project funded by the Shah Family Global Innovation Lab in collaboration with Purdue University and World Concern. 

Chirchir’s scholarly contributions include peer-reviewed publications in high-impact journals, such as the Journal of Agricultural Water Management, and presentations at international conferences. He co-authored seminal studies on biodiesel production, distillery wastewater treatment, and agricultural brine reuse, blending theoretical rigor with practical innovation. As an educator, he imparts expertise in Soil and Water Pollution Control and Environmental Health Technologies, mentoring the next generation of scientists and engineers. Recognized for interdisciplinary collaboration and globally relevant solutions, his work bridges academia and real-world environmental challenges, cementing his role as a key player in sustainable engineering.
