Research Interests

  • Adolescent risky behaviors (mainly dating violence, substance abuse, sexting)
  • Egocentric social network and health outcomes
  • Prevention programs for adolescent risky behaviors

My program of research is centered on prevention sciences with two main focus: 1) adolescent risky behaviors and 2) use of new technology in prevention programs.  Adolescence can be a time of exploration of romantic relationships and development of risky behaviors. Yet the complexity of the development of risky behaviors has not been fully unpacked. Besides, due to advances in technology, current teens have encountered new risky situations including sexting. The ways in which new technology may contribute to adolescent risky behaviors, as well as how new technologies can be employed as prevention tools, have been relatively less studied. My overarching research goal is to identify underlying mechanisms that influence future risky behaviors (e.g., substance abuse, violence), identify specific sub-populations and/or characteristics to frequently engage in these behaviors, and scientifically evaluate prevention programs targeting such mechanisms with adolescent populations.
