Meet the team

Our research group is based in the School of Psychology and Neuroscience, at the University of St Andrews, in Scotland. We study the ethology of wild animals to gain a better understanding of their and our behaviour and minds. Ethology is the process of ‘interviewing’ an animal in their own language (Tinbergen). Our research spans great apes – chimpanzees, bonobos, gorillas, orang-utans, and humans – as well as elephants and more, and focuses on long-term field studies in the wild.

Here’s a bit more about our research team…

Principal Investigator

Catherine Hobaiter 

Cat is a Reader at the University of St Andrews. She studies the evolution of communication and social behaviour in wild apes. Her work on gesture focuses on wild apes across Africa, and she is often based in Budongo, or at her new field-sites in Bugoma, Uganda, and Moyen-Bafing, Guinea. You can find Cat’s publications here and the lab GitHub here.


Current Researchers

Gal Badihi

Gal is a graduate research student at the University of St Andrews. Her research looks at how the social dynamics of chimpanzees in Budongo impact the rates of aggression and lethal aggression in the community.

Gabriela Bezerra de Melo Daly

Gabriela holds a Fyssen Fellowship. She is a social anthropologist trained in primatology.  She completed her PhD at École Normale Supérieure in 2018, studying human-chimpanzee social relations in Japan. Her work focuses on cross-cultural differences in social learning and interaction between humans and chimpanzees.

Vesta Eleuteri

Vesta completed her MSc exploring the form and function of buttress-drumming in five communities of wild chimpanzees across populations in East and West Africa. She is now extending her work on gesture to include elephant communication in a collaboration with our lab and the University of Vienna.

Elodie  Freymann

Elodie is studying for her PhD at the University of Oxford with Susana Carvalho and Mike Huffman (Kyoto University), and is collaborating with our lab on a study of self medicative behaviour and its acquisition in the Budongo chimpanzees. Read about Elodie’s pathway to science here..

Kirsty Graham 

Kirsty completed her PhD at the University of St Andrews in 2016. She studies the gestures of wild bonobos at Wamba, DRCongo and her current postdoctoral research focuses on incorporating philosophical and linguistic approaches to ape communication. You can find Kirsty’s publications here and her brilliant comic versions here

Charlotte Grund

Charlotte is a PhD student at the University of St Andrews. Her current research investigates the natural gestural repertoire of wild mountain gorillas in Bwindi, Uganda and assesses the gestures’ communicative function across individuals, age-sex groups, and behavioural contexts.

Matt Henderson

Matt is a graduate research student at the University of St Andrews. He previously studied the vocal communication of chimpanzees in Budongo, and his PhD investigates gesture use around the world in pre-linguistic human children and through online playback studies.

Harmonie Klein

Harmonie is a PhD student at the University of St Andrews. She has studied wild chimpanzee behaviour since 2017. Her previous work focused on hunting and food sharing in Central African chimpanzees in Gabon. Her current research compares social dynamics in three chimpanzee communities (Sonso, Waibira, and Mwera) in Uganda in two different field sites (Budongo and Bugoma).

Viola Komedová

Viola is studying for her MSc at the University of St Andrews and is working on a systematic study of perishable tools in the Budongo chimpanzees and beyond. You can help contribute to her work by filling in her survey on leaf tools!

Alexander Mielke

Alex holds a post-doctoral Leverhulme Fellowship exploring syntactic structures in ape communication. His previous work includes studies of mangabey social behaviour and chimpanzee facial expressions and play.

Daniela Rodrigues

Daniela is a PhD student at the ISPA in Portugal. Her research collaboration with our lab explores the development of communication and accommodation in human and chimpanzee gestures.

Alexandra Safryghin

Alexandra is a PhD student at the University of St Andrews. Her research looks into the presence of human language laws in chimpanzee gestural communication, with a focus on how familiarity and context affect the duration and frequency of gestural performances.

Charlotte Wiltshire

Charlotte is a PhD student at the University of St Andrews. Her research focuses on exploring machine learning approaches to automate feature tracking and behaviour coding in ape gesture and tool using.




Richard Byrne

Dick is an emeritus professor at the University of St Andrews. He studies communication and cognition across numerous taxa. You can find Dick’s publications here.

Erica Cartmill

Erica is a Professor at UCLA. She studies the role of gesture in language evolution and acquisition. Her lab conducts research on both human children and non-human great apes (orang-utans and chimpanzees). More here.

Brittany Fallon

Brittany completed her PhD at St Andrews in 2016, studying gesture in chimpanzee sexual displays. Her research includes facial expression use in American Sign Language and parallels with chimpanzee facial expression.

Emilie Genty

Emilie is currently studying joint action coordination in chimpanzees, bonobos, and human children, focusing on communicative signals (gestures, vocalisations, and other visual signals). Emilie’s research & photography.

Eve Holden

Eve is a lecturer in the School of Psychology and Neuroscience at the University of St Andrews, and works on chimpanzee behaviour, like female vocal communication, and cross-cultural human development.

Hella Péter

Hella is a PhD student at the University of Kent. Her project focuses on leaf-tools in wild chimpanzees, especially leaf- and moss-sponge use and construction.

Adrian Soldati

Adrian is a PhD student at Budongo, Uganda. His ongoing research includes chimpanzee vocalisations, multi-signal and multi-modal communication, and the social aspect of communication. More here.

Joanne Tanner

Joanne completed her PhD at St Andrews in 1998, studying the untaught gestural communication of gorillas at San Francisco Zoo. Joanne continues to research and write as an independent researcher. More about Joanne here.
