Our work brings together advanced epidemiological methods and large administrative databases (e.g., electronic healthcare records) to understand the causes and consequences of mental disorders. The focus of our research has been to analyze the impact of mental disorders on several health and societal outcomes, including comorbidity and mortality. My research group is also focusing on understanding the social determinants of mental disorders in a broader context. Poor socioeconomic position is an independent risk factor for many adverse health outcomes, and it is strongly associated with poor mental health. Thus, understanding the interplay between these two factors is particularly important. Finally, my team is also working on new methods to address the limitations of electronic databases, e.g., by incorporating information on lifestyle factors – which is usually ignored in register-based research – through the use of surveys, or new methods to accommodate shifts in patient characteristics over time. These methods allow us to have more valid and accurate studies that will help us better guide policies and clinical practice.
