Research Interests
Andrew is interested in decision-making about cognitive effort. In particular, he's interested in what role dopamine plays in learning costs and benefits and also translating instantaneous motivation into promoting or undermining cognitive control.  When he's not investing cognitive effort in his work, he spends his time rock climbing, getting riled up about politics, and reading the news obsessively.
