My research has focused on how effort valuation turns into exertion of effort. In general, humans tend to exert more effort when it is worth it, that is, when the reward outweighs the behavioral cost. Our research shows that this isn't always the case – dynamic adjustments of effort might only come about when the reward pertains to multiple shots at a task, rather than a one-off attempt. Additionally, my research ranges from pro-environmental effort to the ways in which the brain supports dynamic effort exertion based on current demands and rewards.
