"The true biologist deals with life, with teeming boisterous life, and learns something from it, learns that the first rule of life is living"

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.

Passive acoustic monitoring (eseentially, listening underwater) is an efficient way to study acoustically active animals but identifyng which species made a call is still a challenge. C-PODs are logging devices that automatically detect echolocation clicks from small toothed whales, but aren't always great at distinguishing between species. We developed a classifier based on a generalized additive model, and by pooling model predictions on individual click trains within acoustic encounters 98% of all trains could ultimately be classified. This method should allow researchers to obtain increased precision in assigning calls to species using these cost-efficient and widely used devices.

Research
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.

Evolutionary modelling
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.
