My research focuses on understanding and predicting how life history strategies enable parasites to quickly respond to disease control methods, and what the consequences are for the efficacy of disease control.
Organisms change (evolve) to adapt to their living conditions, leading to a maximum reproductive success in that environment. However, the best strategies to grow, survive and reproduce (life history strategies) in one environment, may not be the best strategies in another environment. What happens to organisms when the environment changes, especially if changes result from human action?
