Trained as a social psychologist, Mogilner Holmes's research focuses on the role of time for happiness. Her work provides empirically based knowledge to inform how individuals should think about and spend their time to make their lives better. Her research can be organized into three primary streams: 1) the effects of focusing on time (vs. money), 2) the effects of age (and the amount of time people feel like they have left in life), and 3) optimal ways of spending time.

Among her findings on the topic of time and happiness, her research has identified that merely thinking about time (vs. money) boosts consumers' happiness both with their products^[24] and in their lives;^[25] age influences the way people experience happiness (as peaceful vs. exciting)^[26] and the types of experiences (ordinary vs. extraordinary)^[27] that produce happiness; gifting time through experiences cultivates happiness in relationships;^[28] and to feel happier, people should spend their days on a variety of activities but their hours on more similar activities.^[29]

Professor Cassie Holmes is the author of the Wall Street Journal bestselling book, Happier Hour: How to Beat Distraction, Expand Your Time, and Focus on What Matters Most, which is based on her popular MBA course, Applying the Science of Happiness to Life Design. She also gave a well-received TEDxManhattanBeach talk about how to find extraordinary happiness in ordinary moments.
