  • Screening of Fontan patients in Australia and New Zealand for long-term liver and kidney damage (NHMRC funded) (2013-2015) (N = 152)
  • Functional outcomes after Fontan surgery examining anti-coagulation and fenestration in relation to bone density, cardiac, exercise and neurologic outcomes (NHMRC-funded) (2014-2017)
  • Neurocognitive outcomes in children and adults with a Fontan circulation (HeartKids funded) (2016-2017)
  • Transition from paediatric to adult care for individuals with a Fontan circulation (NHMRC funded) (2014-2019)
  • From the Heart study examining wellbeing and quality of life in individuals with a Fontan circulation and their families (NHMRC funded) (2014-2019)
