In 2019, Brelon May joined NREL as a postdoctoral researcher where he now works on integration of heteroepitaxial systems to enable substrate reuse for photovoltaics. His research interests include epitaxy and growth of dissimilar material systems and nanostructures.

Brelon received a bachelor's degree in chemical engineering from Clarkson University in 2013. He obtained his doctorate in materials science and engineering from the Ohio State University in 2019. During that time, his work involved the epitaxial growth of various material systems (nitrides, oxides, and selenides) and focused on nanowire-based ultraviolet LEDs.
