About Timothy's Work

Timothy Onuh is a Ph.D. candidate in the Department of Chemical Engineering at the University of Massachusetts Amherst (UMass Amherst) and is originally from Nigeria. He received a B.S. in Chemical Engineering at Ahmadu Bello University in Nigeria. Timothy’s dissertation research focuses on improving the sustainability and efficiency of micro and nanoparticles contaminant removal from wastewater treatment systems. Specifically, his notable research achievements involve developing models that aid in the design of wastewater systems that better predict the capture and removal of contaminants from waste streams which in turn mitigate the removal of these contaminants from the receiving environments, ultimately safeguarding public health. Timothy received the National Science Foundation ACADEME Fellowship in 2025, the Education USA OFP scholarship in 2021, and is currently a student trainee in the NIH -UMass Biotechnology Traineeship Program.

Outside the lab, Timothy is passionate about and actively advocates for evidence-based science policy. Timothy first entered the science policy field as a young scientist in Nigeria and volunteered for several months as an environmental policy advocate. He subsequently interned at a World Bank funded research center, communicating recommendations to influential government stakeholders and generating high-quality, evidence-based data to inform policymakers about the state of solid minerals in Nigeria. Most recently, Timothy was selected to represent UMass Amherst at the American Association for the Advancement of Science Catalyzing Advocacy in Science and Engineering Workshop on Capitol Hill, where he engaged directly with national policymakers advocated for science and engineering priorities.

Timothy also loves to work with students and currently serves as an Assistant Residence Director and House council advisor in UMass Residential life, where he oversees residential operations and mentors undergraduates from underrepresented populations. Timothy is looking forward to the Switzer Fellowship as an opportunity to accelerate the impact of his research by engaging with mission-driven professionals passionate about water equity and environmental sustainability and justice.  In his free time, Timothy enjoys travelling, watching soccer, spending time with his family, and cooking. Those who have tasted his cooking say he should consider opening a restaurant.
