​
Mark Johnson is an electronics engineer with a strong interest in animal biology. His engineering focus is in developing instruments and data processing techniques for studying animals in the wild. His biological interests are in sensory ecology, foraging, and predator-prey interactions primarily in the marine environment. To explore the behaviour of wild animals, he has developed highly integrated multi-sensor data loggers such as the DTAG. These tags have been applied to animals from more than 30 species yielding insights into foraging and social behaviour as well as the effects of human disturbance, and are being used in the CCAS project to study spotted hyenas.
Vlad Demartsev

​
Vlad is a behavioural ecologist with a strong preference for field-based, experimental work. He is generally interested in mammalian vocal communication, especially in the coordination of signalling within a group and in the dynamics of continuous signalling interactions over time. His research within the CCAS project focuses on meerkats.
Eli Strauss
Michigan State University, USA & Max Planck Institute of Animal Behavior, Germany
​
Eli is a postdoc at the Max Planck Institute of Animal Behavior. In this project, Eli is using conventional and remotely-sensed data on social interactions of spotted hyenas (e.g., aggressive or affiliative behaviors) to understand how social relationships influence fission-fusion dynamics and, conversely, how patterns of space use influence the way individuals experience their societies.
Baptiste Averly
University of Konstanz & Max Planck Institute of Animal Behavior, Germany
​
Baptiste worked as a PhD student from 2018-2022 on the link between communication and collective movement in meerkats. To tackle this topic, he collected high resolution acoustic and spatial data of wild habituated meerkat groups using custom-made collars, and analyzed the resulting tracking data to understand how influence is distributed within meerkat groups.
Emily Grout
University of Konstanz & Max Planck Institute of Animal Behavior, Germany
​
Emily is a PhD student at the Max Planck Institute of Animal Behaviour studying communication and collective movement in coatis found on Barro Colorado Island and Gamboa in Panama. She uses GPS collars with audio recorders to determine how coati groups use vocal communication for group coordination.
Pranav Minasandra
University of Konstanz & Max Planck Institute of Animal Behavior​
​
Pranav is a PhD student at the Max Planck Institute of Animal Behavior. His PhD addresses a range of questions involving all species involved in the CCAS project. Pranav also conducted his Master's thesis within the CCAS project, working on quantifying behavioural state dynamics in spotted hyena using methods from machine learning, and is currently preparing this work for publication.
Lily Johnson-Ulrich
University of Zurich, Switzerland​
​
Lily is a postdoc at the University of Zurich. She is investigating how the social and physical environment affect meerkat movement decisions. In particular, she is investigating how vocalisations influence collective movement decisions and the mechanisms underlying meerkat spatial cognition & navigation.
Sabrina Salome
Michigan State University, USA​
​
Sabrina is a research assistant working with Kay Holekamp on spotted hyeans. Sabrina works on the organization and processing of spatial, demographic, and behavioral data from the hyena clan we intend to collar as well as on labelling hyena vocalizations from audio data. She is broadly interested in movement ecology and is undertaking an analysis of how, and with which clanmates, hyenas use particular landscape features within their territory.
