Summary
There is no health without mental health, and the foundation of the latter is largely laid in adolescence. Recent evidence indicates that today's adolescents (i.e. Generation Z) experience worse mental health than the preceding generation (i.e. the Millennials). The EU-funded GenerationZ project aims to examine individual changes in adolescent mental health, and assess cross-national variation and trends in population-level adolescent mental health across 40+ European countries. The project's work is in line with the 2030 Sustainable Development Goals and the European regional and national health strategies.

My research addresses critical contemporary challenges in adolescent health and mental health, with a strong focus on cross-national perspectives. Using large-scale nationally representative datasets, complemented by smaller qualitative and quantitative studies, I investigate time trends and mechanisms behind adolescent mental health changes. My work has demonstrated a significant decline in adolescent mental health over time, with factors such as school stress, family support, and structural inequities contributing to these trends. A key focus of my research explores gender disparities in adolescent well-being. I have shown that gender gaps in mental health widened during the COVID-19 pandemic across 45 countries and that structural factors, such as gender inequality, explain variations in risk behaviours and bullying involvement. I also study the psychological impact of climate change on young people, an emerging and urgent issue. Currently, I am validating new measures on climate change emotions and impacts within Ireland and across Europe and Southeast Asia to better capture these effects. Additionally, I contribute to advancing the validation of research instruments for cross-national adolescent health studies, leading efforts on tools like the WHO-5 Well-Being Index and instruments measuring mental health, problematic social media use, and sexual health behaviours. My leadership in international research is reflected in my role as Chair of the Mental Health and Well-being Focus Group within the Health Behaviour in School-aged Children (HBSC) network and as a member of the WHO Global Action for Measurement of Adolescent Health (GAMA) Advisory Group. Furthermore, I contributed to the WHO Europe Child and Adolescent Health Strategy (2025-2030), now under consultation, and authored several WHO reports on adolescent health and well-being, demonstrating the policy relevance of my work and my capacity to translate research findings into policy recommendations. These contributions underline my research leadership in addressing adolescent health challenges globally and my commitment to impactful, interdisciplinary research.
