My main research interest is in the field of aging and age-related diseases, applying molecular epidemiological methods. At the moment I am conducting analyses of different biological age predictors (telomere length, epigenetic clock, frailty index, etc) in several twin studies of aging (SATSA, GENDER, HARMONY, OCTO-Twin, TwinGene) within the Swedish Twin Registry and also using UK biobank data. Methods that I use include longitudinal modelling, causal analyses using Mendelian Randomization, and large-scale genome-wide approaches.
