RESEARCH INTERESTS: I'm an experimental social psychologist. I study social cognition with a focus on temporal contexts. My research uses the lens of time and change to understand conundrums like: Why don't people recognize obvious problems? Why do people celebrate self-improvement yet punish others for past misdeeds? Why is it easy to make a positive impression but hard to make it last? I study the psychological processes underlying such issues and their applications to resolving conflict and boosting well-being.
The core theoretical insight from my research is that people ought to think "in time" more than they typically do - that is, people tend to under-appreciate how things in the present will change and be judged differently upon looking back at them - which I find significantly contributes to such issues. As I test and find, interventions that target people's temporal thinking can therefore help resolve such issues.
For example, I've used this insight to develop broader frameworks that explain when and why people fail to see progress vs. decline (click here for a review) and that highlight how hedonic adaptation is not as pervasive as the field paints it (click here for a review).
