Justin Trias (CV)

Senior Research Associate
School of Mathematics
University of East Anglia

I am currently a postdoc at University of East Anglia (UEA), where I was already from November 2019 to September 2021, working with Shaun Stevens on the research grant project Local theta correspondence: a new study through the theories of types and l-modular representations. From September 2021 to December 2023, I was a postdoc at Imperial College London hosted by David Helm. My thesis work "Correspondance thêta locale ℓ-modulaire" started in 2015 under the supervision of Alberto Mínguez at Sorbonne Université. I defended it in October 2019.
