The Research Group on Adolescent Health (GRSA) is part of the Center for Primary Care and Public Health (Unisanté) and Lausanne University (UNIL). It produces quantitative, qualitative and clinical studies focused on adolescents, young adults and their entourage.
Professor Joan-Carles Suris
Professor Joan-Carles Suris’s studies concentrate on 4 axes. First, adolescents and young adults with chronic illness. For this theme, his research focuses both on risk behaviors and on transition from pediatric to adult care. He is also interested in substance misuse (e.g. tobacco and cannabis) including use of young athletes. Sexual behaviors are also part of his work (e.g. unwanted sexual experiences and sexual dysfunctions). Finally, new addictions such as gambling and problematic Internet use are current study subjects.
