Research statement

I study the causes and consequences of consistent individual differences in relation to the collective behaviour of animal groups. In particular, I investigate the mechanistic underpinings and ecological factors that drive behavioural variation, how this affects social interactions and collective processes, and how in turn the social context determines individual performance. In my research I combine a strong experimental approach, using controlled automated testing facilities and custom-written tracking software, with experiments under semi-wild conditions and field observations, currently primarily on fish.

Public Outreach

2018
Together with Dutch Design Studio Toer I developed an interactive light installation, School of Lights. Inspired on the schooling behavior of fish, a group of lights are controlled and programmed to move automatically and independently, hurrying away and moving closer together when someone approaches. Watch a video of the installation here. School of Lights was exhibited during the international design festival Dutch Design Week, Eindhoven, NL, 20-28 Oct
2018
Participated in the Lange Nacht der Wissenschaft, the yearly science festival of the University of Konstanz, with a swarming light installation and video projections
2018 – 2019
Created a long-term public video installation in the interactive media house of the MPIO that showcases the role of individual differences in schooling fish.
2017 – 2018
Was featured twice on German National Television in two special programs on Collective Animal Behaviour.
2015
Gave a Public lecture about Animal Behaviour for High School students at the Linnean Society in London, the world’s oldest biological society.
2015
Live guest on the Naked Scientists show, one of the most populair science podcasts in the world.
2015
Live interview on Radio BBC5 to talk about my most recent paper on leadership in fish.
2014 – Now
Created a youtube channel (link) and website and blog (jollejolles.com) for my research group the JollesLab to document our on-going research, deliberate about academia, and provide insights into the life of a Behavioural Ecologist.
2013 – 2016
Involved in a collaboration with Dutch and Belgian musicians and film makers to artistically showcase animal behaviour research to the general public. One project, a musical submersion into the evolution and individual variability, toured as a theater show through parts of Western Europe.
2012
Live interview with Radio BBCWales about my research on animal personalities.
2012
Gave a public talk at the Wildlife Trust, Shrewsbury, UK about my experiences of becoming a scientist: The social life of animals: the making of an Ethologist.

Programming and Engineering

  • Developed AnimRec, a publicly available Python package (download link) that facilitates automated image and video recording with Rapsberry Pi computers, specifically designed for Behavioural Scientists and easily usable for people with limited knowledge of coding.
  • Developed AnimTrack, a Python package (currently in beta) build on OpenCV that enables the automatic tracking of both individual and groups of tagged and untagged animals. Features user interface modules for configuration and feature selection, methods for the checking and correcting of tracking errors, a manual tracking method, and data processing and visualation functionality.
  • Designed and fully constructed my own experimental fish lab, including custom-build individual holding tanks for 128 fish and a large experimental setup that features a large 1.5m x 2.5m tank dividable into 8 sub-tanks, a solid aluminium framework covering the tanks from outside disturbances, controlled, dimmable visible and IR lights for recording in complete darkness, and a network of 8 linked RaspberryPi computers for automated recording.
  • Developed a portable recording system for controlled animal recordings in the field, featuring an easy-to-install aluminium framework, foldable fish tank, and a battery-powered Raspberry Pi that can be controlled from a mobile phone, all fitting in a large backpack.
  • Extensive experience with R and Python for modelling, statistics, and data processing; owner of web-design company and broad knowledge of HTML, CSS, PhP, WordPress; fluent with Raspberry Pi and Mac, Windows, and Linux operating systems; considerable experience with Adobe photoshop, After Effects, and Premiere Pro for photo and video editing.
