Profile

Following an undergraduate project studying chromosomal evolution which, coupled with inspirational teaching, sparked a lifelong fascination with evolution, Rob Hammond attained a PhD studentship and teaching assistantship at Oxford Brookes University studying the evolution of the colours and patterns of moths.

With molecular genetics increasingly applied to evolution and ecology, Dr Hammond set about learning and applying these techniques at the Institute of Zoology. A first postdoc took Dr Hammond to Saudi Arabia working on the conservation genetics of gazelles (and baboon population genetics), setting up a molecular lab and training personnel. A second investigated social evolution using the ant, Leptothorax acervorum as a model. Dr Hammond’s focus on social evolution continued at the University of Lausanne studying social conflicts and the organisation of social insects.

In 2006 Dr Hammond began teaching and supervising PhD students as a lecturer at the University of Hull whilst continuing to research social evolution and collaborating with Dr Africa Gomez on sexual mode evolution in the ancient crustacean order, Notostraca.

In 2010 Dr Hammond moved to Leicester and continues to teach, supervise PhD and MSc students, and research evolutionary questions (see Research tab for details).


Research

Dr Hammond’s research (funded by the NERC, BBSRC, and Genetics Society) focuses on the evolution and consequences of haplodiploidy and complex adaptations.

The genetic consequences of haplodiploidy: In Hymenoptera (ants, bees, wasps, sawflies) and other insects, males are haploid and females diploid. Selection is predicted to act differently on genes expressed as haploids or diploids. These ideas are tested 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? The behavioural and genetic underpinnings of variation in social organisation are investigated 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? These questions are investigated using the crustacean Order, Notostraca. 

The dynamics of complex societies and resolution of social conflicts: Societies exist in a balance between cooperation and conflict. Dr Hammond has a long-standing interest in investigating the dynamics of within colony conflicts to test the predictions of kin selection.
