About me

  • I am Docent, Assistant professor, and leader of the research group Cardiometabolic epidemiology and aging. My main interest is combining genetic and longitudinal designs to understand complex aging-related traits. My primary research aim is to understand how obesity influences late-life health, by studying how differences among adiposity-related traits and why they have different associations with age-related diseases such as dementia, cardiovascular disease, and type-2 diabetes. I am also involved in several projects aiming to understand how different factors across the life course affect dementia risk, including genetic factors, lifestyle, and environmental exposures.

Research

  • Adiposity and the risk of age-related disease
    The project aims to leverage the heterogeneity of adiposity-related traits, to understand better how adiposity influences the risk of cardiovascular disease, type 2 diabetes, and dementia. My hypothesis is that specific adiposity-related traits have different effects on the risk of the age-related diseases, and that these differences are explained by differences in e.g. metabolic factors or accelerated aging. I study adiposity in general (e.g. BMI and body fat distribution), and specific adiposity-related traits: a) metabolically unhealthy vs healthy adiposity, b) environmentally vs genetically driven adiposity, and c) adiposity measured in midlife vs late-life. These adiposity-related traits are associated with substantially increased, vs only slightly increased or even decreased risk of age-related disease (compared to having normal weight), and by studying what differs between them, I aim to advance our understanding of both the heterogeneity of overweight and of how adiposity in general affects late-life health.


    The Interplay of Genes and Environment across Multiple Studies (IGEMS) consortium
    I am part of the IGEMS consortium, which integrates data across twin studies of adult development and aging to address issues of gene-environment interplay in Alzheimer’s Disease and related dementias (ADRD). Within IGEMS, I lead studies of cardiometabolic risk factors of ADRD and am the lead of the Statistical Methods work group and the Genotyping and Polygenic Scores work group.
