Simone Pika

Simone Pika has spent over a decade studying the diversity of animals' communicative systems and underlying cognitive mechanisms in captive and natural settings with a special focus on primates and corvids. Recently, she extended this research avenue to include artifical intelligence, multi-modal communication, phenomena of convergent evolution and turn-taking.

Samuel H. Cosper

Samuel Cosper began his postdoc position in the CBC group in November 2020. He completed his PhD in Neurolinguistics at the University of Osnabrück in 2020, where he focused on the role of object modality and temporal congruency of stimulus presentation on word learning in infancy and adulthood. His postdoctoral project focuses on developmental aspects of turn-taking in human infancy and childhood, as well as a human and non-human primate inter-species comparison.

Kayla Kolff

Kayla started her PhD in the CBC group in August 2020. Her project will centre on the impact of the social environment on turn-taking communicative behaviour in wild Eastern chimpanzees, living in the Kibale National Park, Uganda. 


Bas van Boekholt

Bas van Boekholt started his PhD in 2020 in the CBC Group. He did his masters at Utrecht University, the Netherlands and has studied the flexibility of vocal communication in vervet monkeys in South Africa and reconciliation in long-tailed macaques. His PhD will focus on the development of turn-taking and social skills of chimpanzees living in the Ngogo community, Kibale National Park, Uganda.

Lara Southern

Lara Southern started her PhD in the CBC group in November 2019. Her research examines the turntaking in wild chimpanzees. She is particularly interested in the environmental factors unique to Loango National Park in Gabon and their subsequent effect on the communicative interactions between the individuals of the Rekambo community.
