Joshua R. Sangoro

Associate Professor


Joshua Sangoro is an Associate Professor in the Department of Chemical and Biomolecular Engineering, The University of Tennessee, Knoxville (UT). He received his doctorate in Experimental Physics in 2010 from the University of Leipzig (Germany) with Prof. Friedrich Kremer. His dissertation research focused on studies of ionic liquids by broadband dielectric spectroscopy. Sangoro worked as a Research Scientist at the University of Leipzig until early 2012 when he joined the Chemical Sciences Division of the Oak Ridge National Laboratory as a Postdoctoral Research Associate. In 2012, he was awarded the Feodor-Lynen Research Fellowship by the Alexander von Humboldt Foundation.

Sangoro joined the Department of Chemical and Biomolecular Engineering at the UT in the fall of 2013. He has authored or co-authored over 60 peer-reviewed articles and book chapters, and he also has contributed to over 68 (26 invited) technical presentations at national and international meetings. He is a recipient of the ARO Young Investigator Program as well as the NSF CAREER awards. His current research focuses on understanding the underlying mechanisms determining dynamics and ionic conduction in soft materials across multiple length- and time-scales. His current research projects are supported through grants from the National Science Foundation, Department of Energy Office of Science, and Army Research Office.


Our research program focuses on experimental and computational efforts aimed at developing scientific frameworks for understanding the correlation between the chemical structure, microscopic organization and dynamics, and how these relationships determine physicochemical and electrochemical properties of relevance to current and future energy technologies. A central theme of our research is to develop fundamental foundations for rational design of novel safe, efficient, and environmentally benign electrolytes.

Our current research interests can be broadly categorized into three main areas, namely, (i) Mesoscopic Structured Liquids (particularly ionic liquids and deep eutectic solvents), (ii) Polymer Dynamics, and (ii) Broadband Dielectric Spectroscopy and its Applications.
