Graduated with a PhD from Harvard University, working with Fiery Cushman. Justin’s research focuses on the ways in which humans regulate each others’ behavior. In particular, his research has focused on how humans use punishment to change others’ behavior, and how this adaptive purpose has shaped the processes underlying punishment. In tackling this question, Justin has employed online, in-lab, developmental and neuroimaging studies. During his postdoc, Justin will apply this same approach to understanding how humans make partner choice decisions.
