Aron Walsh is a Royal Society University Research Fellow and Full Professor in the Department of Materials. He leads the Materials Design Group.

Aron joined Imperial College London in October 2016. He was awarded his PhD in Chemistry from Trinity College Dublin. He then worked for the US Department of Energy at the National Renewable Energy Laboratory (NREL), followed by a Marie Curie Fellowship hosted at University College London, and a European Research Council Fellowship held at the University of Bath.

His research involves cutting-edge materials theory and similation applied to problems across solid state chemistry and physics, including materials for solar cells and solar fuels, information storage, batteries, thermoelectrics and solid-state lighting. He has a particular expertise in the theory of semiconductors and dielectrics, and is developing innovative solutions for materials data, informatics and design.

These activities are supported by funding from the Royal Society, EPSRC, ERC and Horizon2020.

In 2015 Aron was awarded the EU-40 prize from the European Materials Research Society and the Chemistry Society Reviews Emerging Investigator Lectureship for his work on the theory of next-generation materials for solar energy conversion, including hybrid halide perovskite photovoltaics. In 2017 he was a recipient of the Philip Leverhulme prize in Chemistry, and was named a Fellow of the Royal Society of Chemistry.
