Do active systems posses leaders – units that influence the system more than how they are influenced by them? The answer obviously depends on the specific system at hand and it is of primary importance in biology. Understanding this is indeed akin to ask what are the causal relations between different agents, or between each agent and macroscopic properties of the system. In this internship, we will study the application of recently developed techniques for causal inference to assess whether leaders can be reliably identified in active systems. The work will have analytical and numerical components.
