Research / Scholarly interests
Tim’s research focuses on loneliness and its impacts on health across the lifespan, with a particular focus on adolescence and emerging adulthood. His work integrates longitudinal, epidemiological and behavioural genetic methods to study the implications of loneliness for mental health, employment, technology use, sleep, inflammation and other markers of health and functioning. He is particularly interested in the mechanisms through which loneliness can develop from a temporary experience to a chronic problem that persists for months or years. Most recently, he is interested in researching how novel technology can be leveraged to advance ways of understanding, measuring and combatting loneliness.
