Professor Parry Guilford, MSc, PhD

Director, University of Otago, Center for Translational Cancer Research, Dunedin NZ

Parry has been working on HDGC since 1995, when he teamed up with a New Zealand Māori family to try and uncover the cause of stomach cancer running through several Māori communities. Following the identification of CDH1’s role in 1998, his research group in the Cancer Genetics Laboratory, University of Otago, moved on to studying how CDH1 mutations lead to cancer. Over the last five years, the focus has shifted to the development of drugs which can be used to prevent and treat diffuse gastric cancer and lobular breast cancer in HDGC families.
