98. Laura Wesseldijk: Behavioural genetics, music, and the importance of twins

BJKS Podcast

Laura Wesseldijk works at the Max Planck Institute for Empirical Aesthetics in Frankfurt at the Behavioral Genetics unit in collaboration with the Department of Psychiatry at Amsterdam UMC. We talk about her research on the genetics of music and mental health, methods in behavioural genetics, the role of large samples, the importance of twins for behavioural genetics, and much more.
BJKS Podcast is a podcast about neuroscience, psychology, and anything vaguely related, hosted by Benjamin James Kuper-Smith.
