I'm currently a postdoc in the Statistical Laboratory in Cambridge. Prior to this I spent some time postdoccing in Lausanne, at the EPFL, after completing my PhD in Lancaster.

My main research interest is all aspects of extreme value theory; see below for a list of publications. I'm particularly keen on developing new statistical methodology for extremes, motivated by deficiencies of existing frameworks for practical problems.

  • Teaching

    I have previously taught the Extreme Value Theory MSc course at Lancaster, and the Applied Statistics course at EPFL. In Michaelmas 2013 I taught part of the Part III course in Applied Statistics in Cambridge.
