Dr. Roselyn A. Ongulu

Dr. Roselyn Ongulu holds a PhD in Analytical/Environmental Chemistry, specializing in adsorption of heavy metals from waste water by biosoption and phytoremediation. She is a member of staff in the Department of Pure and applied Chemistry at Masinde Muliro University of Science and technology where she has worked for 12 years. She previously taught chemistry and Mathematics in high school and in TVET Institutions for over 15 years. Current research activities with post-graduate students: Use of locally available plant resources for phyto-remediation of potable contaminated water by endocrine disrupting chemicals (NRF funded), biosorption selected ARVs from model waste water and mycochemical analysis of kenyan medicicinal mushrooms.
