Current Projects

My personal research interests include commitment in couple relationships, romantic relationship formation, marriage, decision making during emerging adulthood (18-29 year olds), and Marriage and Family Therapy theory. I am currently exploring with my research team a new phenomenon in romantic relationship formation which I call just talking. With the substantial adoption of smartphones and the use of social media, emerging adults are communicating and forming relationships in unprecedented ways.

In January 2018 I finished writing a book with my colleague Dr. Alexandra Schmidt Hulst entitled Contextual Therapy for Family Health: Clinical Applications. This book is contracted through Routledge and is currently in the production process. This book will be published and available on June 20th. You can pre-order this book from: Amazon, Barnes & Nobel, Target, Walmart, or directly from our publisher Routledge.

Currently I am collecting data and collaborating with Dr. Leah LeFebvre who is a professor in the Department of Communication at the University of Alabama. We are investigating the role of technology in romantic relationship formation and rejection.
