Background

Jacob joined the Department of Biology as a Senior Lecturer in July 2016. From 2012–2016, he was a Lecturer in the Division of Biological Anthropology at the University of Cambridge.

He originally trained in Zoology at the University of Edinburgh. He then went on to study for an MSc and PhD in Anthropology and Primatology at the University of Barcelona. From 2010–2012, he carried out postdoctoral research at the University of Cambridge.

Over the last few years, Jacob has been carrying out research into primate vocal communication and the evolution of language. His research takes a broad comparative perspective, ranging from detailed descriptions of vocal anatomy, through to recording animal sounds, carrying out playback experiments, and using macroevolutionary analyses to test evolutionary hypotheses.

He collaborates closely with the Fitch lab in the Department of Cognitive Biology at the University of Vienna.

Jacob is the Director of our Behavioural Ecology Research Group.
