George J. Nelson Ph.D.
Mechanical & Aerospace Engineering
Mechanical Engineering, Georgia Institute of Technology
George Nelson received his Bachelor of Science, Master of Science, and Ph.D. degrees in Mechanical Engineering from the Georgia Institute of Technology in 2003, 2006, and 2009. While pursuing his Ph.D., his research involved modeling and analysis of fuel cells and electrolyzers, with an emphasis on mass transport in porous fuel cell electrodes. After completing his Ph.D., he served as an Assistant Research Professor at the University of Connecticut from 2009-2012. His projects at the University of Connecticut focused on the investigation of mass and charge transport in electrochemical energy storage and conversion devices, primarily fuel cells and batteries. During this time he also contributed to the development of three-dimensional imaging methods for energy materials based on x-ray nanotomography. Dr. Nelson started as an Assistant Professor at UAHuntsville in August 2012. His general research interests include transport phenomena, energy storage and conversion devices, sustainable energy systems, and multi-scale modeling and analysis.
