I am a Lecturer in Pure Mathematics at the
University of Manchester. Before moving to Manchester in November 2015, I was a Research Associate at the
University of Bristol
(September 2013 - June 2015), a Postdoc Researcher at
Universität Zürich (September 2011 - August 2013), an
EPSRC Postdoctoral Fellow at the
University of Oxford (October 2008 - August 2011), and a Visiting Researcher at the
University of Rochester
(March 2008 - August 2008). I completed my PhD at the University of Bristol in March 2008 under the supervision of Prof.
Jon Keating FRS.
My Erdös number, and also Erdös number of the second kind are 2 (via
Richard Hall).
Research interests
Analytic number theory: analytic theory of the Riemann zeta-function and L-functions, distribution of primes; Sieve methods; Number theory in function fields; Random matrix theory...
