I have previously worked mostly on wild cetaceans, but now I am developing theoretical investigations of the evolution of social learning strategies, as well as getting involved in experimental studies of learning. I am primarily interested in the evolution of social learning, communication systems and culture, but maintain broader based interests in ecology, behaviour and conservation.

I am a Reader in Biology supported by the Marine Alliance for Science and Technology Scotland (MASTS). I am affiliated with the Scottish Ocean Institute, Sea Mammal Research Unit, the Centre for Biological Diversity, the Centre for Social Learning and Cognitive Evolution, and the Institute of Behavioural and Neural Sciences.
I have broad research interests, largely centred around the evolution of learning, behaviour and communication, with a special focus on marine mammals.
Dunn, C, Tyack, PL, Miller, P & Rendell, LE 2017, 'Short first click intervals in echolocation trains of three species of deep diving odontocetes' Journal of the Acoustical Society of America, vol 141, no. 2, pp. 900-907. DOI: 10.1121/1.4976084
Sometimes deep-diving odontocetes make 'double clicks' at the start of echoloction click trains. In this paper we analysed inter-click-intervals in recordings from suction cup tags. We refer to these 'double clicks' as short first intervals (SFIs). We found that the context of SFI occurrence varies across three deep-diving species - Blainville's beaked whales (87% of click trains that were preceded by a terminal buzz started with an SFI), Cuvier's beaked whales (only sub-adult animals produced SFIs), and sperm whales (much more likely to produce SFIs on the first click train of a dive). These species differences in click production could provide a window into the evolution of odontocete echolocation.

Sperm whale society and ecology
I have been studying the ecology, communication and societies of sperm whales, the largest of the toothed whales, showing how long lasting social groups use distinctive vocal dialects that appear to be culturally transmitted. Part of this work is my involvement in running the Balearics Sperm Whale Project and as a collaborator of the Dominica Sperm Whale Project.
Culture in whales and dolphins
In whales and dolphins we find examples of both complex communication and apparently widespread social learning, a simple form of culture. I am using statistical models to assess the evidence for social learning in wild cetaceans.
I also use evolutionary simulation models to understand how these processes like social learning might have evolved, and how they might be related to the evolution of other kinds of behaviour, such as cooperation and niche-construction.
Human social learning
I use experimental approaches to understand how we negotiate the trade-offs involved in deciding whether to use social information to make simple decisions, as a window into how we have evolved to make best use of our cultural inheritance.
East Coast Marine Mammal Acoustic Study (ECOMMAS)
We are deploying passive listening buoys along the Scottish coastline in collaboration with Marine Scotland Science to monitor the impact of coastal windfarm development and also to give insight into acoustic behaviour of marine mammals.
