Ertan Agar, Ph.D. joined the Department of Mechanical Engineering at the University of Massachusetts Lowell as an Assistant Professor in the Fall of 2015. He earned his Ph.D. degree in Mechanical Engineering from Drexel University in September 2014. His Ph.D. dissertation work was a combined experimental and modeling effort, which was aimed at understanding the species transport mechanisms governing capacity fade in vanadium redox flow batteries. Following his doctoral studies, Agar worked as a post-doctoral researcher in the Electrochemical Engineering and Energy Laboratory at Case Western Reserve University. In this role, he worked on performance diagnostics of flowable slurry electrodes for cost-effective flow batteries. His research interest includes design and diagnostics of flow-assisted electrochemical systems, including redox flow batteries for grid scale energy storage and capacitive deionization for water treatment and desalination.
