Professor Michael Boyer
About Professor Michael Boyer
Michael Boyer is a medical oncologist who has practised for more than 20 years. He specialises in thoracic and head and neck cancers. He is the Chief Executive Officer of Chris O'Brien Lifehouse, a not-for-profit comprehensive cancer centre in Sydney. He was appointed Chief Clinical Officer there in 2011 and has been involved in the Lifehouse project from the start.
Earlier, he was Director of Cancer Services for the Sydney South West Area Health Service. He holds a clinical professorship in the Central Clinical School at the University of Sydney. He has a medical degree from the University of Sydney and a doctorate in cell biology from the University of Toronto. He became a Member of the Order of Australia in 2010 for work in education, clinical trials research and integrated cancer care. In 2021 the International Association for the Study of Lung Cancer gave him its Adi F. Gazdar Merit Award.
Public records of his angel investing are thin. PitchBook lists him as an angel investor based in Sydney with one recorded investment, in Medow Health. It also describes him as an advisor to Medow, where his role is to help the company understand clinical governance and the needs of hospital administrators. No other angel investments, check sizes or exits are public.
Medow Health AI raised A$3.5M in September 2026 entirely from existing shareholders, including Boyer and orthopaedic surgeon Michael Solomon. The round took Medow's total seed funding to A$8.5M. Funds are going to AI Front Desk, a product that answers and triages inbound patient calls for specialist clinics.
Medow was founded in 2023 and started as an AI scribe for specialist doctors' medical reports. The new round follows a A$2M raise in January 2025 and a A$3M raise in November 2025. Sources do not say how much Boyer put into each round.
There is no public statement from Boyer on stage, sector, geography or check size. His one recorded investment is a seed-stage Australian health AI company. He is also a clinician and hospital executive, so his experience is in clinical governance and cancer care. Founders should treat this as a single data point, not a stated thesis.
