Mathematics is key to controlling epidemics. With a well-constructed model, we can accurately predict the dynamics of infectious diseases, eventually finding ways to control them.

I spent the last two months turning Liberty City (from the original Grand Theft Auto) into an agent-based simulator. I relentlessly studied contact graphs, transmission trees, infection heatmaps, and SEIR curves to find a way to stop the epidemic (that I started).

Here’s how:
