Studying for a PhD in mathematics with the probability and statistics group at Durham University, supervised by Dr Andrew Wade and Dr Ostap Hryniv. For more information on the group, in particular information for prospective PhD students, see here.

My main areas of interest are the topics of stochastic processes, random graphs, and applications in random networks. My current focus is on functionals of random walks and in particular the convex hulls of random walks.

With my thesis in preparation, I am looking for my next move. I have an open mind as to which specific area of work I move into, but my main focus is web/system development, mathematical modelling, data science or of course the possibility of continuing my research in a probability group — all of which excite me! I am only looking for opportunities in Vest-Agder or Aust-Agder, or possibilities of doing remote work.

Meetings and seminars:

The Research Students’ Conference came to Durham in 2017, it was a fabulous week with students from across the country sharing their work and meeting other students in a relaxed atmosphere. Please click on the following links for more information. RSC Webpage, RSC 2017 booklet, RSC 2018 – Sheffield.
