Ertan Agar, Ph.D. joined the Department of Mechanical Engineering at the University of Massachusetts<br>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. <br>
