About me
I am a postdoctoral fellow at the University of Cambridge, researching non-commutative algebra and representation theory. I am funded and supported by the Heilbronn Institute for Mathematical Research.
I completed my DPhil at the University of Oxford in 2020, after which I was a Heilbronn fellow at the University of Manchester until October 2023, when I began my current position. I believe mathematics is an unparalleled discipline, and I hope to continue practicing it in the future for as long as I can.
Research Interests
My research is primarily in non-commutative algebra, often with application to representation theory. I usually work in a p-adic or non-archimedean setting, and one of the main goals of my research is to advance the representation theory of p-adic groups.
I have worked closely with the completed group algebra, or Iwasawa algebra, of a compact p-adic Lie group, which was the main focus of my DPhil research. In several cases, I have completely classified the prime ideal structure of these algebras. I have also explored other classes of rings, arising from related constructions, including skew-power series rings and completed enveloping algebras. More recently, I have begun to explore the smooth, modular representation theory of locally compact p-adic Lie groups, and I have utilised Bruhat-Tits theory to develop a better understanding of this topic.
My other interests include Galois theory, algebraic number theory and tropical algebra.
Teaching
I have given small group tutorials and supervisions, in Oxford, Manchester and Cambridge, for a variety of undergraduate subjects including Linear Algebra, Commutative algebra, Representation theory and Lie algebras. I have also tutored Galois theory, given lectures in non-commutative algebra, and supervised an undergraduate project on profinite groups.
In Lent term 2025 in Cambridge I lectured a Part III course in Coxeter Groups of my own design, the notes for this course are available here.
