I am currently modeling the movement, mortality, and impacts of two species of exotic beetles, the polyphagous shot hole borer, and the tamarisk leaf beetle (TLB model mostly being done by my final graduate student from the previous life in academia). These beetles are important because they impact the habitat vegetation of an endangered bird, although in very different ways. Agent-based modeling is a different approach to science that allows for experiments in silico. The model is refined by attempting to have it reproduce patterns in the real world. The most interesting part, aside from the joy of coding itself, is the complex behaviors that emerge, often that could not have been predicted beforehand.
