Profile

BA Hons. (Mod.) PhD

I was born in Dublin. After completing a BA(mod) in Zoology at Trinity College Dublin I studied for a PhD in ant colony self organisation with Professor Nigel Franks at the University of Bath. A move to Switzerland and bumblebees followed where I worked with Professor Paul Schmid-Hempel at the ETH Zurich. At the ETH I studied the role of immunity in pollinator behaviour. This continued when I took up my position at the University of Leicester. My current research involves studying epigenetic factors in social insects.

Research

Epigenetics is defined as the heritable change in expression of a gene without any change in the DNA sequence. Everything we do - diet habitat social interactions even aging - causes chemical modifications on genes that will turn those genes on or off: epigenetic changes. Many diseases including cancer and Alzheimer's show epigenetic changes between the normal or healthy state.

We research epigenetics in insects mainly bumblebees and wasps. We do this both as a model of more complicated systems - like humans - and because of insects’ importance in our survival. For example insect pollination services are worth 14.2 billion euros to Europe's economy.
