Broadly, I conduct reseearch in judgment and decision-making, with a focus on how social competition impacts various social and health outcomes.
I am interested in a variety of topics, including morality, cooperation, signaling, social comparisons, and inequality. Within these topics, I investigate how individual differences (personality; wise reasoning; relative deprivation) interact with contextual factors. I also rearch how social competition influences cultural change, where I use historical data to investigate change within cultures over time.
My research is interdisciplinary, often exploratory, drawing on diverse fields (social/personality psychology; evolutionary psychology; organizational behaviour; behavioral economics; behavioral ecology; health psychology; cognitive science) and employs a variety of methodological approaches (behavioral experiments; experimental economics; meta-analysis; longitudinal analyses of time-series data; and survey methods).

I conduct research in judgment and decision making and cultural change. I seek to understand the underlying social and affective processes that influence moral and cooperative decision-making, including social and motivational influences (e.g., reputation), affect (e.g., feelings of relative deprivation), individual differences, and underlying reasoning processes (e.g., the use of wise reasoning) that influence moral decision-making.
I also conduct research on cultural change, where I investigate how socioecological factors influence cultural phenomena over time. I am also interested in how people predict cultural change.
My work is purposely interdisciplinary, drawing on research in social/personality psychology, health psychology, behavioural economics, and evolutionary biology. I use a variety of measures and methods in my research program (e.g., experimental psychology; time-series analyses; meta-analysis; game theory).
