My undergraduate project studying chromosomal evolution - coupled with inspirational teaching - sparked my lifelong fascination with evolution. This led to a PhD studentship and teaching assistantship at Oxford Brookes University studying moth colour/pattern evolution.
With molecular genetics increasingly applied to evolution & ecology, I set about learning and applying these techniques at the Institute of Zoology. My 1st postdoc took to me Saudi Arabia - working on the conservation genetics of gazelles (and baboon population genetics) - where I set up a molecular lab and trained personnel. My 2nd investigated social evolution using the ant, Leptothorax acervorum as a model. My focus on social evolution continued University of Lausanne studying social conflicts and social organisation social insects.
In 2006 I began teaching and supervising PhD students as a lecturer at the University of Hull. Here I continued researching social evolution and collaborating with Dr Africa Gomez on sexual mode evolution in the ancient crustacean order, Notostraca.
In 2010 I moved to Leicester where I continue to teach, supervise PhD / MSc students and research evolutionary questions (see Research).
My research (funding: NERC, BBSRC, Genetics Society) focuses on the evolution and consequences of haplodiploidy & complex adaptations.
The genetic consequences haplo-diploidy. In Hymenoptera (ants, bees, wasps, sawflies) - & other insects - males are haploid and females diploid. Selection is predicted to act differently on genes expressed as haploids or diploids. We test these ideas in social insects and plants.
Evolution and organisation of social groups. There is great diversity in the organisation of social groups, but how does this diversity arise? We investigate the behavioural and genetic underpinnings of variation in social organisation using the ant, Leptothorax acervorum.
The evolution and consequences of variable sexual mode. Variation in modes of reproduction raise questions as to how this variation arose and what are the genetic consequences? We use the crustacean Order, Notostraca, to investigate these questions.
The dynamics of complex societies and resolution of social conflicts. Societies exist in a balance between cooperation and conflict. I have a longstanding interest in investigating the dynamics of within colony conflicts to test the predictions of kin selection.
