My research focuses on close relationships and their underlying mechanisms. I'm investigating the psychological aspect of behavioral systems, especially the attachment, care giving, and sexual mating systems.

To achieve this I'm using a multi method multi level approach including neuroimaging techniques, physiological measures, endocrine markers, as well as questionnaires and RTs measures.

One main line of research is focused on the effects of increasing people's sense of attachment security on their tendency to engage in pro-social behavior, their altruistic and sexual attitudes, and their goals, as well as their attentional strategies.

In a separate line of research, I'm looking at online and offline social networks, their characteristics, and the way they change over time. I also look at the links between one's attachment style and his or her social network.

Research Interests

  • Personality and social psychology
  • Social neuroscience
  • Research on attachment theory (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)
  • Social networks.
