Dr Mills alongside her collaborator Dr De Vivo (BASES accredited), has been involved in a number of projects focusing on physical activity during pregnancy. Most recently a partnership with ukactive secured a substantial grant to develop and deliver an intervention to support physical activity maintenance during pregnancy. Dr Mills and Dr De Vivo have also been involved in updating the physical activity during pregnancy information on a national resource used in undergraduate teaching on health and medicine programs across the UK. Dr Mills has supervised three doctoral level students researching aspects of this topic area and continues to develop industry partnerships and projects to address physical activity issues during and post pregnancy.
