He is also a doctoral or PhD student in the University of the Basque country, where he is in the last year of his PhD in Forensic Analysis entitled: "Microevolutive Genetic processes in Roma population based in the Basque Country: A Short Tandem Repeat marker based study." Before that he has been working 3 and a half years as a Laboratory Biologist in a private hospital in Spain. His research interests include twin studies, population health and obesity. At PopHel, he is currently studying body mass index changes and fluctuations and how these are related with different typology of diseases (cardiovascular, metabolic, endocrine...) apart from the genetic and environmental influences of the relationships. He mainly uses twin databases. Contact:

Olivia McEvoy started as a postdoc at PopHel in September 2024. Prior to this she gained her PhD in Sociology from Trinity College Dublin, entitled “Studies on the social and economic patterning of health behaviours,” which included a research stay at Epidemiology & Public Health, University College London. Her research interests include social theory, social stratification, social inequalities in health and the biological, material, cultural, psycho-social, and contextual determinants of these inequalities and statistical methods. At PopHel, she is currently studying family and peer influence on health behaviours and the relationship between social composition of contexts, such as school and neighbourhood, and resulting health inequalities.

Eevi Haverinen joined PopHel as a doctoral researcher in September 2024, working on Niina Metsä-Simola's Research Council of Finland-funded project, Social Determinants of Neurodevelopmental Disorders and their Consequences within Families. She holds a master's degree in social science from the University of Helsinki, specializing in Social and Health Research and Management. With a clinical background in pediatric and adolescent mental healthcare, Eevi's research interests include social epidemiology, child and adolescent mental health, and the social determinants of health. At PopHel, she is currently studying the social determinants of neurodevelopmental disorders and their educational consequences in children and adolescents. Contact:

Eugenio Paglino started as a Postdoc at PopHel in September 2024. Previously, he was at the University of Pennsylvania, where he completed his PhD in Demography and Sociology, with a dissertation titled “The Demography of Shocks: Migration and Mortality under the Influence of Environmental and Epidemiological Shocks”. His research interests include population health, mortality, migration, their links with climate change, and social and geographic inequalities in health and mortality. He is also interested in formal demography and statistical methods for modeling demographic processes. At PopHel, he is currently studying the health and mortality profile of internal and international migrants relative to the native-born population as well as the role of migration in shaping geographic inequalities in health and socioeconomic indicators.

Anna Leuwer started as a doctoral researcher at PopHel in October 2024. She completed her master’s degree at the university of cologne in social research, with a specialization in econometric and psychometric methods and their application in causal inference. In her master's thesis, she investigated trends in mental health through a birth cohort comparison among German young adults between 2002 and 2020.Her research interest lies in the field of population health, with a particular focus on social inequalities in younger age groups and their roots in intergenerational interdependencies, such as socio-economic family background and childhood circumstances. Other areas of interest include health-risk behaviors and mental health, as well as the study of long-term changes in health inequalities and their determinants. At PopHel, she will investigate social disparities in harm associated with substance abuse among Finnish adolescents, their variability across birth cohorts, and their consequences for health and social status at subsequent life-stages.
