Dr Priyad Ariyaratnam


NIHR Clinical Lecturer and Speciality Registrar in Cardiothoracic Surgery

Role at Hull York Medical School

I am an NIHR Clinical Lecturer (Post-doctoral research in cardiothoracic surgery), and Speciality Registrar (National Training Number) in Cardiothoracic Surgery in the Yorkshire & Humber Deanery.


I am a Higher Speciality Registrar (NTN) in Cardiothoracic Surgery and am due to finish my clinical training in October 2021. I completed my research Doctorate at Hull York Medical School (University of York) in 2015 in Pulmonary Hypertension and am currently continuing this laboratory research alongside clinical research in cardiothoracic surgery. Prior to this, my basic surgical training was undertaken in Leeds and Hull. My undergraduate degrees in Medicine (with Distinction) and Biomedical Sciences (1st Class Honours) were at the University of Southampton where I also completed my postgraduate Foundation Training. I grew up in Cheshire where I attended St Ambrose College.
