Motion Reconstruction of Animal Groups: From Schooling Fish to Swarming Mosquitoes (~14 MB)


Perceiving human crowds

With increased urbanization, human pedestrian crowds are a phenomena frequently witnessed in cities all over the world. In this context, the usefulness of robots in human societies will critically depend on their ability to actively navigate dense crowded situations. A first step in this direction is to automatically interpret crowd motion. This project seeks to develop and validate an algorithmic framework for the perception of dynamic environments. The research objective is to use methods in Bayesian estimation and statistical pattern recognition to robustly and reliably classify crowd motion from a level perspective.

Causal relationships underlying the collective dynamic behavior of swarms

Living in groups affords several benefits for animals such as better feeding opportunities and reduced predation risks. In both instances-foraging and predator avoidance-critical information is transmitted nonverbally throughout the group, at different time scales. This project, carried out in collaboration with Dynamical Systems Laboratory, New York University, seeks to demonstrate that an information-theoretic approach can be used to measure social animal behavior. The research objective is to establish a rigorous model-free framework to study causal relationships in animal interactions validated by a series of hypothesis-driven experiments on zebra fish to emphasize unidirectional information transfer.

Natural and Engineered Collectives Laboratory

The Natural and Engineered Collectives Lab (NECoL) conducts research in the general areas of applied dynamical systems, robotics, and pattern recognition. Research questions are themed around complex systems such as animal groups and multi-robot systems, mixed collectives of animals and robots, as well as homogeneous groups of cooperating, competing, or conflicting individuals.
