Mahshid Ahmadi

Assistant Professor


Dr. Mahshid Ahmadi received her PhD in Materials Science and Engineering from Nanyang Technological University, Singapore in 2013 with focus on development of low cost materials for energy applications. She graduated with B. Sci. (2004) and M. Sci. (2007) in Materials Science and Industrial Metallurgy from Shiraz University, Iran. Prior to joining UTK, she worked as a research and technology consultant in a start-up solar cell company in Dallas, TX. She then moved to UT as a postdoctoral researcher in 2015 and as a research assistant professor in 2017. Currently she works on synthesis and development of hybrid organic-inorganic perovskites for high radiation energy sensors, study electronic and ionic charge transport and probing unusual defects in this class of materials. She has active research collaborations with scientists in Oak Ridge National Laboratory (ORNL), Charles University, Prague and Chemical and Biomolecular Engineering and Nuclear Engineering at UTK. She has authored and co-authored around 30 peer-reviewed articles. Her recent project on development of hybrid perovskites for dual gamma-neutron detectors was covered in the spring edition, Tennessee Engineer (2018).
