Consultant in Diabetes, Endocrinology and General Internal Medicine.

I graduated from the Poznań University of Medical Sciences. Between 2008 and 2024 I worked in the United Kingdom where I completed my foundation training and specialty training in general internal medicine, diabetes and endocrinology. In 2015 I received the Lewis Thomas Gibbon Jenkins of Briton Ferry Fellowship from the Royal College of Physicians Wales to complete research on characterisation of extracellular vesicles in human obesity. This led to obtaining the Doctor of Medicine (MD) degree from Cardiff University in 2018 (Supervisors: Prof Aled Rees, Prof. Philip James) Since 2019 I have worked as Consultant in General Internal Medicine, Diabetes and Endocrinology at the University Hospital of Wales.

I am a member of various British and European medical societies such as The Royal College of Physicians UK, Diabetes UK, European Society of Endocrinology and Society for Endocrinology UK.
