Dr. Van Lieshout is interested in the developmental origins of health and disease and does research that examines the impact of adverse prenatal exposures on offspring brain development and in particular psychiatric and cognitive problems across the lifespan. He is particularly interested in the impact maternal perinatal psychopathology (e.g., postpartum depression) has on offspring neurodevelopment, and in developing interventions to help prevent the intergenerational transmission of depression and other psychiatric disorders.

He is also interested in the impact of mothers’ weight and weight gain during pregnancy on offspring brain development, as well as the mental health consequences of being born at extremely low birth weight.

Dr. Van Lieshout also holds the Albert Einstein/Irving Zucker Chair in Neuroscience.


Current Activities

  • Examining the impact the treatment of women with postpartum with cognitive behavioural therapy on offspring neurodevelopment
  • Examining the impact of a maternal pregnancy nutrition and exercise intervention on the neurodevelopment of offspring
  • Examining the mental and physical health outcomes of extremely low birth weight survivors in adulthood
