Gillath conducts research in social psychology and social neuroscience focusing on attachment theory (including individual differences in attachment orientation; brain mechanisms and genetic polymorphisms underlying these differences; attentional processes related to these differences; relations between the attachment, caregiving, and sexual behavioral systems as they affect adult relationships); prosocial motivation and behavior (compassion and altruism); affiliation, social networks, and friendship processes.
Professor Gillath inspires enthusiasm and growth not only in his myriad of classes at the University of Kansas, but among Scholars and layperson with his lectures, publications, blogs and Ted Talk.
Gillath has published two books: Relationship Science (Integrating Evolutionary, Neuroscience, and Sociocultural Approaches) and "Adult Attachment: A Concise Introduction to Theory and Research".
