Dr Wozniak graduated with distinctions from Wroclaw Medical University, Poland in 2006 and undertook his postgraduate medical training in the UK. Following initial training posts in West Midlands he transferred to the East of England region where he completed specialist training in Respiratory and General Internal Medicine.  He gained further education and training in Sleep Medicine at the Respiratory Support and Sleep Centre at Royal Papworth Hospital where he worked as a Senior Clinical Research Fellow. During this fellowship he was awarded two external research grants and delivered three NIHR Portfolio research studies which examined associations between obstructive sleep apnoea and glaucoma, including the impact of CPAP on ocular pressure and microvasculature. For this work he was awarded a PhD.

He is a certified European Expert Sleep Specialist (Somnologist) and an active member of the British Thoracic Society Specialist Advisory Group on Sleep Apnoea.

Dr Wozniak was appointed to his consultant post at Royal Papworth Hospital in 2018 where he combines clinical work with research and medical education.

He undertakes sleep disturbance clinics, general respiratory clinics and provides specialist care for people needing invasive and non-invasive ventilatory support.
