Sarah Cotterill is an Assistant Professor in the School of Civil Engineering. She completed an Engineering Doctorate (EngD) at Newcastle University in 2016, as part of the STREAM industrial doctoral cente. Her doctorate, sponsored by Northumbrian Water Ltd, focused on scaling-up Microbial Electrolysis Cells (MECs) for wastewater treatment and energy recovery. She built and tested four successively larger MECs, which produced hydrogen gas throughout these trials. Following this she worked for a start-up business focused on internet of things (IoT)-enabled rainwater management systems. In 2017, Sarah was awarded a Fulbright "All Disciplines" Scholar award for research at The Pennsylvania State University. After this, she joined The Water Hub at Durham University - a European Regional Development Funded (ERDF) project - which brought together public, private and third sector businesses with academics and practitioners to deliver innovation in the water and environment sectors. Sarah joined UCD in August 2019.
