CV

I study the mechanisms and consequences of collective behavior in biological and social systems. I am especially interested in understanding how animal groups make collective decisions and coordinate collective action, and in particular how these processes are affected by the social relationships between group members and the communication strategies they employ. I work across a range of study systems to tackle these questions, in close collaboration with researchers across a variety of disciplines.

Originally from Chicago, I did my undergraduate degree in Physics at Swarthmore College, then did my PhD in Quantitative and Computational Biology at Princeton University. I then moved across the pond to Europe, where I held post doc positions at the Max Planck Institute for Ornithology and the University of Zurich before moving to Konstanz in 2018. When not working, I enjoy traveling (especially via Swiss transit), cooking, eating, riding my bicycle, and learning German.

I am a behavioural ecologist interested mainly in the topics of mammalian vocal communication in social settings.  For the past 9 years, I have focused on the interplay between different aspects of the social environment with different aspects of signalling tactics and signal structure. I have investigated how the presence, composition and attentive state of conspecific audience affect individuals` signalling behaviour. On the flip side, I have explored how individuals` are able to maximize their gain from signalling and reach a more abundant and attentive audience by correctly timing their signalling events and also producing signals which are more effective in gaining and maintaining audience attention. 

Currently, I am in the process of conceptually and methodologically developing a project dealing with the motivational phase of vocal signalling in an attempt to detect the animals' preparations and intentions to vocalize. Additionally, I am also interested in investigating animals’ ability to maintain continuous vocal interactions which include multiple interactions turns and dynamic informational content.  I have a very strong preference for field-based, experimental studies, as they allow us to witness animal behaviour in its natural ecological and biological contexts.

Postdoctoral Researcher

I am an ecological modeller working as a postdoc in the group. I am using machine learning to classify calls in meerkats, hyenas and coatis, to better understand how communication influences group dynamics over multiple spatial and temporal scales. My research focuses on many different aspects of animal movement – How do we track animal movements? How can we analyse and understand individual behaviours? How does this influence population-level dynamics? And how do we protect a species when it is in perpetual motion?

Prior to this, I worked as a postdoc at the Swiss Ornithological Institute (bird migration) and at the Centre for Ecology and Hydrology (agricultural management), after completing my PhD at the University of Queensland (conservation planning). I did my undergraduate at the University of Aberdeen (Ecology) and my Masters at the University of York (Computational Biology).

I am interested in understanding how animals within social groups perceive and interact with one another, exchanging and exploiting information to adjust their behaviour in different ecological contexts. What particularly fascinates me is the question of how local interactions between individuals can scale up to complex and relevant group-level responses that are more than the sum of their parts. After undergraduate studies in France and Canada, for my Master’s thesis I studied the use of social information in multi-species flocks of tits foraging during winter along an altitudinal gradient.

For my PhD, which I started in September 2018, I am collecting high-resolution spatial and acoustic data on whole groups of meerkats in their natural habitat using custom-made collars, to understand how collective decision-making is achieved during group movement in this social species with complex vocal communication. Of particular interest to me is the way individual variations and social structure can influence how pairs of individuals respond to one another in different contexts of movement, and how this ultimately affects patterns and processes at the group level.

I am interested in the behavioural ecology of social mammals, with a focus on field-based data collection. My undergraduate degree was in Zoology at the University of Bristol, where I continued as a masters by research student. For my masters, I studied alloparental care in a habituated population of wild dwarf mongooses in South Africa at the Dwarf Mongoose Research Project. I collected detailed observations of adult-pup interactions to assess the different types of alloparental activities which are exhibited and whether dominance status, sex and age influenced variation between these caring tasks.

For my PhD, I will be studying communication and collective movement of white-nosed coatis, which live in forested areas in the Americas. I will be recording acoustic and movement data from the majority of coati group members using custom built collars to analyse how group cohesion is coordinated and maintained through acoustic communication. I am excited to be combining detailed field-based observations with new tracking technologies to answer questions about the mechanisms underlying collective movement in social mammals.

Over my four years at the Indian Institute of Science, I have worked on various projects in ecology and evolution that have made me really interested in thinking about how animals move and interact with each other. I like working on projects with theoretical, computational, and field-based components. I have worked on modelling the group size distribution of an antelope species, looked at how the permeability of vegetation affects animal movement strategies, and modelled habitat use and population dynamics in a risk-reward-heterogeneous environment. 

 

As part of my one-year Master's degree in Biology (2019-2020) at the Indian Institute of Science, I am working on developing a classifier that successfully predicts hyena behaviorual states using accelerometer data, learning from a recording-based ground-truth from five hyenas. The classifier, which will be a hierarchical node-based implementation, will be validated paying attention to the time-series of behavioural states. I also intend to ask relevant biological questions regarding hyena activity patterns, and try to answer them using this classification algorithm and rigorous statistics.

 

In the future, I will work towards a PhD in movement ecology and/or collective behaviour, with emphasis on theoretical and computational approaches.

I graduated from Flinders University, South Australia with First-Class Honours in a Bachelor of Science (Animal Behaviour) combined with a Bachelor of Behavioural Science (Psychology). My main focus for my Honours was looking at the interaction between Behavioural and Physiological Responses, as well as individual differences in stress levels and personality, to determine appropriate conservation measures to help sustain at risk populations. I’m also very interested in the evolution of cognition in animals particularly in social living species, looking at such areas as; their innovative abilities, different learning style, and how these differ between the sexes.

Since graduating I have completed an internship working with little penguins (Eudyptula minor) on Philip Island, Australia using accelerometer and GPS biologgers to help determine their movement whilst out at sea.

Most recently, I have been working at the Kalahari Meerkat Project (KMP), South Africa collecting data on their; co-operative behaviours, group structure and movements, as well as metamorphic measurements. I am currently still on site at the KMP assisting with building and deploying custom collars for the meerkats to collect spatial and acoustic data.
