Biography

George J. Nelson is Professor, Department Chair, and the Ashok K. Singhal Endowed Chair of Mechanical and Aerospace Engineering at the University of Alabama in Huntsville (UAH). His research applies x-ray and neutron imaging methods in concert with modeling and electrochemical testing to connect multiscale geometry and transport interactions with the performance and reliability of energy storage and conversion devices. 

Prof. Nelson received his Bachelor of Science (2003), Master of Science (2006), and Ph.D. (2009) degrees in Mechanical Engineering from the Georgia Institute of Technology. Prior to joining UAH in 2012 he was an Assistant Research Professor at the University of Connecticut, where he contributed to the development of novel 3D imaging and analysis methods for energy materials based on x-ray nanotomography and x-ray absorption spectroscopy methods. 

Prof. Nelson has served ASME through conference organization and committee membership primarily within the Advanced Energy Systems Division, and as an Associate Editor for the Journal of Electrochemical Energy Conversion and Storage.

He is a recipient of an ORAU Ralph E. Powe Junior Faculty Enhancement Award (2013), a National Science Foundation CAREER Award (2015), and a Shull Wollan Center Visiting Researcher Fellowship (2019-2020).
