During the past decade, his interests have branched out toward psycho-neurobiological theories of human relationship, integrating principles of early mother-infant attachment with adult romantic relationships. He speaks to professional audiences on subjects of couples therapy and preventative psychotherapy through early intervention with infants, children and their parents. He has published several articles on the psychobiology of couples therapy and is currently training therapists on his unique approach to couples work using attachment theory, neuroscience, and principles of arousal and affect regulation.
