RCGD Fall Seminar Series on the Science of Social Relationships: Darby Saxbe
The Transition to Fatherhood as a Window for Neural, Hormonal, and Psychological Remodeling

Darby Saxbe of the University of Southern California joins the RCGD Fall Seminar Series on the Science of Social Relationships.
The Transition to Fatherhood as a Window for Neural, Hormonal, and Psychological Remodeling
This talk will review several studies on hormone and brain changes across the transition to parenthood in first-time human fathers. Darby Saxbe et al find that men show cortical volume decreases that are similar to those seen in mothers, but are less significant and more variable. They also show that when men express more motivation to parent, and more engagement in parenting, they show larger gray matter volume decreases. At the same time, gray matter volume decreases are associated with more postpartum mental health problems and poor sleep quality. The talk will also describe research on perinatal resting state connectivity and white matter changes in men, and functional studies on men reacting to infant stimuli and emotional faces.
Darby Saxbe, PhD, is Professor of Psychology at the University of Southern California, where she serves as the current Director of Clinical Training for the Clinical Science program. She has published over eighty scientific articles in peer-reviewed journals, and her research has been funded by major awards from both NIH and NSF. She has earned early career recognition from the American Psychological Association and the Society for Research in Child Development and was a Fulbright fellow to Spain in 2019.
About the series:
Humans are social animals and from the earliest days of life, are dependent on the quality of social relationships with significant others: family, kin, friends, and a growing social network of online acquaintances. But, how do we conduct research and come to understand the social processes transpiring in these significant social connections with others? What are the consequences for individual development and mental health outcomes of having close intimate relationships in one’s life? There is also a darker side to some relationships in the form of violence, aggression, and conflict. How do we study these processes? Social media and artificial intelligence have opened up new ways of thinking about “what is a social relationship?” and how many of these “friends” can one truly have.
The speakers for this series will focus on different types of social relationships, spanning family and parent-child relationships, friendships, peer networks, romantic relationships, attachment relationships, and the use of online media to maintain social connections. Although several speakers are senior scholars with extensive research backgrounds in the field, many are junior scholars who are traversing new paths into the science of social relationships. Please join us Mondays to learn more about the exciting field of social relationships!
These events are held Mondays from 3:30 to 5.
In person: ISR Thompson 1430, unless otherwise specified.
Organized by Brenda Volling and Richard Gonzalez.
As permissions allow, seminars are later posted to our YouTube playlist.
