New levels of biological complexity evolve through the unification of independently replicating individuals into cooperative groups. The emergence of group living – sociality - is a major transition in evolution, and many of our planet’s most ecologically successful and invasive animals are social. My research seeks to understand how biological complexity, primarily in the form of sociality, arises at the level of the genes and the interplay of genes, behaviour and the environment.
My main study organisms are the eusocial insects (bees, wasps and ants). Eusocial insect societies epitomise complex group living, where queens are dedicated egg-layers and their offspring are non-reproductive workers,. Sociality has evolved independently at least 11 times in the Hymenoptera (bees, wasps and ants), resulting in societies that range widely in their degree of complexity, phenotypic plasticity and diversity. My research exploits this remarkable radiation in order to understand how genomes produce phenotypic and behavioural diversity, determine what facets of this diversity account for an individual’s behaviour, and explore how this influences their ecology and robustness to the environment. I address this at proximate and ultimate levels through integrating genetics, genomics, transcriptomics, epigenetics with behavioural ecology on wild populations of non-model organisms. The approach I use combines some of the most recent advances in molecular techniques and state-of-the-art field monitoring technology.
More broadly, I am interested in general genomic patterns underlying the evolution and maintenance of plastic phenotypes. My group is asking similar questions about the genomic basis of phenotypic change in Atlantic salmon, by examining the transcriptional basis alternative parr-smolt phenotypes with the aim of determining the role of olfactory receptors in migratory behaviour.
Current key research areas
Impact and science outreach
I am an active public communicator of science through science writing (e.g. as invited contributor to the Edge Third Culture (www.EDGE.org), New Scientist), public lectures and experiments (e.g. http://edge.org/conversation/a-cooperative-foraging-experiment-mdash-lessons-from-ants, http://www.edge.org/documents/Edge-Serpentine-MapsGallery/index.html. http://www.wellcomecollection.org/whats-on/events/creature- collective.aspx), school events, and science exhibitions. Most recently, I founded and co-organise Soapbox Science – an annual event that brings science to the streets, following the model of London’s Hyde Park Speaker’s Corner. Soapbox Science is used to raise public awareness of the high profile, active community of female scientists we have in the UK. More details about this annual event and associated Women in Science activities can be found on our dedicated website. http://soapboxscience.org/. I also write regularly for the national press on the problems facing women in science and how we can rectify them.
Happy new year!

Two new doctors! Many congrats to Dr Claire Asher and Dr Thibault Lengronne on their successful PhD vivas. Claire is now travelling the world, and Thibault is back in Lausanne, working with Prof Laurent Keller.
PhD thesis submitted! Thibault Lengronne submitted his thesis on Nest drifting behaviour in tropical paper wasps. Hurrah! Well done Thibault!
PhD thesis submitted! Claire Asher submitted her thesis on The dynamics of reproductive dominance in dinosaur ants. Well done Claire!
New PhD students start: Adam Devenish and Robin Southon start their PhDs this month at Bristol. Adam has a NERC funded CASE studentship on "Assessing current and future impacts of invasive ants on ecosystem services". Robin also has a NERC studentship and will be studying "Adaptive value of males in primitively eusocial insect societies". We are delighted to welcome Adam and Robin! Links to their webpages to follow soon!
PhD transfer: Emily Bell will also be enroling at Bristol this month as she moves her university affiliation here. Emily will be continuing her work on "Phenotypic plasticity in Polistine wasps". http://www.zsl.org/science/ioz-staff-students/bell,2041,AR.html
New visitor: Anna Heath has completed her MSc at Univeristy College London, and joins us for a month to finish up her exciting MSc work on the attraction of ants to electric field. Welcome Anna!
New staff: Dr Emilia Santos joins us for a 4 month contract working on a variety of waspy molecular projects. Welcome Emilia! http://evolution.unibas.ch/salzburger/team/esantos/
