Dr. Hugh Geaney

Biography

Hugh finished a degree in Industrial Chemistry in 2008 and a PhD in Chemistry in 2012 (both from UL). He subsequently moved to UCC as a postdoctoral researcher on the EU FP7 project STABLE, working on Li-O2 batteries. Following that, he was a senior postdoctoral researcher in UCC, investigating porous materials for Li-ion battery applications.

In 2016 he returned to UL as a postdoctoral researcher on an Enterprise Ireland commercialization project. In 2019, he received a SIRG (starting investigator research grant) and became an independent, Principal Investigator.

Since 2020, Hugh has been a lecturer in Chemistry in the Department of Chemical Science.
