Research supervision
I've enjoyed working with many, many people over the course of my career so far, conducting research on a wide range of topics. The people below here are some of those with whom I've worked in a research supervision/mentoring role.

Research Visitors
I've hosted a number of research visits, usually of 6 months to 1 year duration, and working with researchers from PhDs to Professors. Here's a selection of them, with links to some of the published research outcomes from our collaboration. I'm always open to further collaboration, so if you'd like to propose a research visit project, please do get in touch!
MSc Research
I enjoy supervising a number of MSc projects each year, including the following in more recent years. (Most project topics proposed by me; overall average grade = 72%, which is a distinction, with 28 distinctions to date!)
