My name is Hanneke Wiersema, currently a Titchmarh Research Fellow at the University of Oxford. Previously I was a EPSRC Postdoctoral Research Fellow and a Herchel Smith Postdoctoral Researcher at the University of Cambridge. I obtained my PhD in Pure Mathematics at King's College London, under the supervision of Fred Diamond and James Newton. My email address is hanneke.wiersema at maths dot ox dot ac uk.
