Jennifer Stellar studies the pro-social and healing effects of positive emotions such as compassion, happiness, joy, and awe. She received her PhD from the University of California, Berkeley and is currently a postdoctoral fellow at the University of Toronto. In her research, she examines whether positive emotions elicit reliable physiological changes and how these emotions impact immunity, stress, and overall physical and mental health. Her paper on the anti-inflammatory effects of awe has generated substantial media interest.
