E-mail: daniel.platt.berlin (at) gmail.com
I'm a postdoc at Imperial College London with a research interest in geometric analysis and machine learning. I previously was a postdoc at King's College London and obtained my PhD from Imperial College London where my advisors were Jason Lotay (University of Oxford) and Sir Simon Donaldson (Imperial College).
