Specialist Orthodontist
BDS(NUI), MOrth(HKU), MOrth(RCSEdin), PhD(ULon)

Following my graduation from dental school in 2002, I have held a range of positions in private practice and teaching hospitals in the UK and Australia. I undertook specialist orthodontic residency training in Hong Kong from 2006-2009 and received a membership diploma in orthodontics from the Royal College of Surgeons, Edinburgh, in 2011.

Since 2011, I have been a registered Specialist Orthodontist in private practice in both the UK and Ireland. I also returned to the UK - where I completed a PhD in at the Centre for Craniofacial and Regenerative Biology in King’s College, London, in 2017.

My work in both private and NHS practice as well as continuing my professional development through advanced-level academic research, has allowed me to offer very experienced and skilled orthodontic treatments.

I lecture several times a year with colleagues from the UK, Europe and Asia and continue to collaborate with several universities in Ireland and the UK in areas such as materials and compliance technology.

My expertise spans the whole spectrum of treatment with a particular interest in AI technologies (such as Dental Monitoring) and additive manufacturing (3D printing) of orthodontic braces and clear aligners.

My wife and I moved back to Dublin from London in 2016 with our three boys, two dogs (Belle - a rescue dog from HK, and Rudi our practice mascot), as well as several motorbikes, one of which I am attempting to restore (a wartime BSA M20- belonging to my dad!).
