Professor Shelling is head of the Medical Genetics Group. His research is primarily interested in understanding the molecular changes that occur during the development of genetic disorders, focusing on breast and ovarian cancer, and reproductive disorders. An understanding of the important changes will eventually provide an opportunity to improve the early detection of disease, and to target more effective treatment. Andrew is extensively involved in teaching reproduction, genetics and cancer at the University of Auckland. Andrew began at Otago University with a degree in Physical Education, and BSc (Hons) and PhD in Biochemistry. He was awarded the Nuffield Medical Fellowship in 1992, and spent three years in Oxford, UK, studying the genetics of ovarian cancer, before being appointed to Auckland University as a Lecturer. Andrew has served as Deputy Head of Department of Obstetrics and Gynaecology, President of the New Zealand branch of the Human Genetics Society of Australasia, Deputy-Chairperson of the Advisory Committee for Assisted Reproductive Technologies and as Associate Editor for the Human Reproduction journal. He is currently Director of the Bachelor of Medical Sciences Honours programme, on the Editorial Board for the Human Fertility journal and is a Trustee for the Nurture Foundation for Reproductive Research. Andrew has been the Associate Dean (Research) at the Faculty of Medical and Health Sciences since 2013.
