The Renormalization Seminar is an informal seminar held at the Mathematics department at Imperial College London. The seminar is loosely focused on mathematically rigorous approaches to the renormalisation as it appears in singular stochastic partial differential equations, quantum field theory, and critical phenomena. 

As an informal seminar we only require titles from speakers and ask that both the speakers and audience be flexible about assumptions on background knowledge (in either direction). The contents of talks can range from unpublished work to expository talks on important mathematical work or open problems.

The seminar is currently organized by Ajay Chandra who can be reached via e-mail at
