After completing his PhD at the University of Manchester in 2013, Lewis took postdocs at the University of East Anglia, the University of Padova and the University of Kent.
His research at UEA was supported by the doctoral prize fellowship, awarded each year to a promising doctoral graduate from any discipline.
At the University of Padova, Lewis held a Marie Sklodowska-Curie fellowship. He used the research funding there to travel widely, starting collaborations at the University of Oregon and the University of Birmingham. These collaborations led to important progress in the modular theory of Yangians and finite W-algebra. The synthesis of these two theories is one of Lewis’ most fruitful topics of current research.
In 2016 Lewis returned to the UK to take up a postdoc at the University of Kent with Stéphane Launois. There he developed his research interests in Poisson geometry, deformation theory and quantum groups.
In 2019 he condensed his research objectives into a UKRI Future Leaders fellowship proposal, which he was awarded. This grant will run until January 2024, with a possible 3 year extension. Funding will be available to hire a postdoctoral research associate working in the field of geometric representation theory and W-algebras. On top of this Lewis is actively recruiting PhD students.
Lewis joined the University of Birmingham in August 2020. As well as carrying his UKRI fellowship status he has been awarded a Birmingham Fellowship for the initial five year period of his contract.
