Hello! My name is Lilly Heffernan and I'm a 2026 Laidlaw Scholar from Trinity College Dublin. I'm interested in the way in which human effects on animal behaviour influence their disease spread. 75% of emerging diseases are coming from animals, and I believe that we can manage this in an effective and humane way. 

I'm exploring this topic by investigating how artificial light changes how bats use space, and stresses their immune systems. I suspect that artificial light negatively impacts bat immunity, making them more likely to spread disease. This may be a reason we are seeing more human pathogens which originate from bats, such as SARS-CoV-2, and Ebola virus. 

I strongly believe that we can curb the spread of these diseases by understanding how our behaviour is affecting our ecosystem. We cannot have healthy humans without healthy animals. This approach targets new pathogens before they spread to humans. If we focus on this angle, we can prevent the inefficient and cruel practice of culling sick animals for our own benefit.
