Gretchen is primarily interested in the evaluation, implementation, and development of evidence-based interventions for improving the health and well-being of children and families.

Gretchen received her DPhil from the University of Oxford in 2009 and followed this by working at the Institute of Psychiatry, King’s College London evaluating the evidence for parenting programmes with the National Academy for Parenting Research. She worked for the Dartington Social Research Unit for nearly 7 years until 2017, specialising in trials and systematic reviews of interventions and conducting the cost-benefit analyses for the Investing in Children project.

She is currently a Postdoctoral Research Associate at the Peninsula Cerebra Research Unit (PenCRU), as part of the NIHR CLAHRC South West Peninsula (PenCLAHRC), situated within the University of Exeter Medical School. Her current focus is on developing and evaluating interventions for children with disabilities and their families.

In her spare time, she enjoys exploring the beautiful Devon countryside with her family.
