Ich bin Verhaltensökologin und evolutionäre Anthropologin, interessiert an der Entstehung sozialer Komplexität. Mit Hilfe von Beobachtung, feldbasierten Experimenten und modernster Fernerkundungstechnologie erforsche ich, wie in Gruppen lebende Tiere Interessenskonflikte überwinden, um gemeinsame Ziele zu erreichen. Ich interessiere mich besonders dafür, wie sich Merkmale auf der Gruppenebene ausprägen und auf welche Weise sie die kollektive Ökologie von Tiergesellschaften beeinflussen.

Als Verhaltensökologin und evolutionäre Anthropologin, interessiere ich mich für das Sozialverhalten der Bonobos, ihre Umweltbedingungen, ihre Rolle innerhalb ihres Ökosystems und ihre Lebensgeschichte. Einer meiner Schwerpunkte ist ihr Nahrungsrepertoire, das extrem vielfältig ist und von reinen Nahrungsmitteln bis hin zu Pflanzen, die zu medizinischen Zwecken genutzt werden, reicht. Dazu verfolge ich einen interdisziplinären Ansatz, der Herbarien, Analysen der phytochemischen und pharmakologischen Eigenschaften von Pflanzen und deren Auswirkungen auf Wachstum, Gesundheit und Fitness einzelner Bonobos integriert.

My group studies the mechanisms and consequences of collective behavior in social animals. We seek to understand how individuals in groups coordinate and communicate with one another to make collective decisions. We combine high-resolution tracking of entire social groups in the wild with boots-on-the-ground field biology, and develop analytical approaches to comprehend the patterns of collective behavior we see in nature.

I am an ecologist specialized in tropical ecosystems. I investigated a diverse array of wildlife in South America, Africa and Asia, putting conservation at the forefront of my work. In my PhD, I focus on the effect of human (Homo sapiens) hunting on mammal abundance and movement patterns. In the wider study site of the LuiKotale Bonobo Project, DRC, I assess the mammal community across areas that have been protected for different lengths of time.

I am an evolutionary behavioral ecologist and anthropologist, combining theoretical approaches like mathematical modeling and empirical field work to study extragenetic inheritance. In capuchin monkeys, we aim to understand how cultural transmission and evolution, different types of social learning, life history, territorial inheritance, and dispersal shape animal behavior and sociality. A centerpiece of our research is the extractive foraging and the evolution of tool use. To understand drivers of its advent, we cross-compare tool using and non-tool using capuchin populations and e.g. map behavior on resource availability.

I am a postdoctoral behavioral ecologist interested in the selective forces shaping sociality and the proposed evolutionary links between sociality and advanced cognition. I study variability in the social structure and cooperative complexity of African lions across habitats with differing levels of resource richness. I aim to identify conditions under which sociality emerges (and breaks down), as well as conditions favoring cognitive complexity during cooperation.

I study group foraging in the Neotropical greater spear-nosed bat. In collaboration with Teague O'Mara and the Dechmann lab, I map resource distribution and combine it with high-resolution movement and acoustic data of whole groups of bats. I investigate how group foraging decisions can be facilitated by social information and the social interactions of the groups.

I am a behavioral ecologist interested in communication in social mammals and its self-regulated coordination. In meerkats, I study the interaction aspect of communication such as the timing of the vocalisation and the social dynamics of vocal exchanges. I also explore breathing as a potential indicator of vocalisation intention and as a possible social cue aiding in regulation of signalling turns.

I am an ecologist, broadly, interested in the interface between spatial and behavioural ecology. As well as a focus on fundamental ecology, I am also interested in how theory can be used to inform conservation and management efforts. These days I mostly work with lions, using long-term datasets on movement and observations to explore how the distribution and richness of resources drive social and spatial structure in populations. I enjoy using quantitative approaches (mostly in R) and working collaboratively.

In my current research I try to understand how an individual’s ability to coordinate with others is affected by experiences early in life and whether these differences ultimately affect individual fitness. I address these questions by studying vocal signals used to coordinate group activity in two study systems, the domestic chicken and the common pheasant. This work is in close collaboration with Dr Joah Madden (University of Exeter) and Prof Andrew Radford (University of Bristol).

I am a behavioral ecologist, studying the cultural transmission of behaviors and how this relates to socio-ecological, environmental, and individual differences. By combining observations with non-invasive experiments and statistical modeling, I aim to learn more about animal culture. I study social learning of stone tool use in island living white-faced capuchin monkeys, with the aim to discover which factors drive the development of this behavior, as island populations seem to be more prone to develop tool use.

I am a behavioural ecologist, interested in communication in social mammals. Collaring white-nosed coatis living in Panama, I collect audio, high-resolution accelerometer and GPS data to assemble a call repertoire in combination with observed behaviours. I study the resulting effects of vocalisations on group cohesion, dynamics and movement, and the influence of environmental variation on mechanisms used in communication.

I am a behavioral ecologist, primarily aimed at understanding the factors governing decision making, leadership and fine-scale behavior of animals in ecologically and socially relevant contexts. I develop state-of-the-art tracking technologies with the minimal equipment to gain maximal reliable information about behavior. I combine field-based observational and experimental approaches with supervised machine-learning to understand how groups solve conflicts of interests relating to food rewards, staying cohesive as a group and reach consensus decisions concerning where to go.

I am a wildlife ecologist, specialized in field-based behavioral research. I am broadly interested in animal movement and space-use in group-living animals. By combining longitudinal data with spatial analytical tools, I investigate how demographic change influences home range behavior in groups of white-faced capuchins. My current research focuses on how sleep site locations can be used to leverage historical data from before GPS technology was introduced. Using this knowledge, I plan to address how within-group energetic requirements and novel spatial information introduced from immigrants drive space-use patterns over the long-term.

I am a behavioral ecologist interested in the evolution of primate social behavior, animal responses to environmental changes, and the enhancement and validation of quantitative methods applied in behavioral ecology. In white-faced capuchin monkeys and red colobus monkeys, two species differing a lot in their ecology, I compare female social relationships and the resulting fitness consequences. I study potential mechanisms underlying this fitness-sociality link by analyzing behavior, physiological parameters, and ecological variability like resource distribution.

I am a behavioral ecologist focusing on the impact of health and disease on animals’ behavior. In the context of the rapid environmental changes we observe in recent years, the study of health in wild animals has become of tremendous importance for their conservation. All great ape species are endangered or critically endangered, with the transmission of diseases from human to ape being one of the main threats. I am particularly interested in studying self-medicative behavior in bonobos (Pan paniscus), investigating how they manage to maintain and recover their health in their natural habitat, the evergreen rainforests in Central DRC.

I am a computational biologist, interested in collective animal behaviour and movement patterns. My work is focused on social factors that affect synchronisation of wake-sleep cycles in animals. in cooperation with the Jordan lab, I will combine theoretical and experimental approaches to study these factors in cichlid fish. Using a model-fitting approach, I will address questions about the social dimension of synchronisation.

I am a behavioral ecologist studying the mechanisms and evolution of sociality via an integrative approach that links physiological mechanisms, behavioral phenotypes, and ecological forces. In collaboration with Zea Walton and the Ankoatsifaka Sifaka Research Project, we investigate the collective ecology of Verreaux's sifaka and their primary predator, the fosa. We employ state-of-the-art tracking technology in conjunction with traditional field observations and long-term data to examine the intersection of social dynamics, spatial decision-making, and predator-prey interactions.

I am a community ecologist specialized in ecological forecasting. I am interested in understanding how the processes that connect individuals respond to environmental variability so we can better predict how large-scale changes in climate, land-use, and resources will change the composition and function of groups and ecosystems. My research program focuses on the social and ecological determinants of decision-making in dispersing male baboons as they leave their natal group, and eventually join a new one.

I am broadly interested in the emergent behaviours and functions in animal groups (and societies). For my PhD, I studied emergent group behaviour of blackbuck (Antilope cervicapra) in the context of predation and mate-choice. I like to employ Computer Engineering concepts and aerial imaging techniques to answer questions related to Ecology. In future projects, I would like to gain a multi-perspective understanding of group-living animals and their ecosystems by employing interdisciplinary approaches. At the MPIAB, I will be studying mate-choice dynamics in blackbuck leks.

I am a computational biologist, interested in the interplay between individual and group level properties in animal societies. I investigate decision-making across scales: how individual behaviour translates to decisions at the group level and thus affects collective motion and information propagation. Currently, I analyse trajectories, construct agent-based models, and use Bayesian inference to study coordination of movement via vocal communication in meerkats.

I am a behavioral ecologist broadly interested in how group-living animals make decisions. Currently, I study foraging decisions by wild bonobos (Pan paniscus) to better understand how individuals optimize their nutrient intake and energetic costs as food availability varies, and how these individual foraging decisions influence group fission-fusion dynamics. I am also investigating how social and environmental factors influence groups’ decisions about when and how to interact with one another.

I am a landscape ecologist interested in understanding how the past and present landscape impacts animal movement and human wildlife conflict. My current research focuses on quantifying nutritional landscapes in tropical forests using remote sensing. I use machine learning with hyperspectral imaging to model tree species distribution and sugar content of Dipteryx fruits. With this, I aim to understand drivers of animal movement and behavior at the community level.

I am a behavioral ecologist and data analyst with a focus on the evolution of cognitive maps, the mental representation of space. I am especially interested in how elements of primate ecology, like a fruit-based diet and arboreal habitat, facilitate the evolution of cognitive maps. To answer this, I study the movement of kinkajous, an arboreal mammal that shares an ecological niche with humans’ primate ancestors. I aim to identify whether kinkajous supplement route learning with place learning.

I am a behavioral ecologist broadly interested in the way social animals exchange information in different ecological contexts, and how this in turn affects group-level outcomes. My main goal is to characterize how meerkats use vocal signaling to maintain group-cohesion and achieve coordination during movement.

I am a behavioral ecologist with a keen interest in group decision-making, movement, social networks, and leadership. I apply social foraging and collective decision-making theory on multiple groups of wild black-handed spider monkeys and white-faced capuchins living on Barro Colorado Island, Panama. To gain a greater understanding of how their physiology influences their foraging, leadership and decision-making processes, I combine GPS data and empirical field research with laboratory analyses of hormones.

I am an ecological modeller using machine learning to classify calls in meerkats, hyenas and coatis, to understand how communication influences group dynamics over multiple spatial and temporal scales. Using GPS and audio data from collared wild individuals, allows us to analyse how group movement and cohesion is facilitated by vocal communication. Looking at inter-species variation gives us insight into differences in short versus long distance communication and differences between very cohesive versus fission-fusion species.

I am a behavioral ecologist interested in how group-living animals navigate a complex social environment and how relationships influence everyday decisions at the individual, the collective and the population level. I study the social impacts on decision-making in wild olive baboons, using GPS, inertial sensors, and video recordings, in conjunction with direct observations. 3D laser scans help me produce a physical reconstruction of sleep sites. I combine these with thermal imagery recordings to unveil agitation at night and to explore the influence of the social environment on sleep in baboon groups.

My main interest is social behaviour of bonobos (Pan paniscus): its evolution, structure and functions. I am fascinated by the dynamics of bonobo networks: how their properties change with ecological factors and how individuals’ positions vary in the potential influence on network structure. Using my mathematical background, I apply social network analysis to study global and local patterns of associations and interactions between individuals within a community. For my MSc thesis, I focused on how network characteristics influence disease spread in the bonobos of LuiKotale.
