Leading medical researcher Professor Stephen Hughes gave Year 12 pupils a fascinating insight into the groundbreaking work he and his team are doing to develop tests and treatments for a host of serious and life-threatening conditions.
Prof Hughes - himself an expert on prostate and bladder cancer and heart disease - spoke of the work done by his Wrexham-based team in a wide range of medical fields and disciplines.
Key innovations being led by the research unit include the development of a new blood test for prostate conditions that could massively improve diagnosis and speed up treatment.
He also spoke of the importance of their teamwork approach involving clinical practitioners such as doctors as well as industry professionals and professional scientists.
Prof Hughes is one of the three directors of the Maelor Academic Unit of Medical and Surgical Sciences. The team aims to give research support to North Wales' three main hospitals - Ysbyty Gwynedd, Glan Clwyd, and Wrexham Maelor.
He also took time to outline the huge career opportunities in the NHS in numerous fields including microbiology, virology, clinical chemistry, and transfusion science.
The talk formed part of the Queen's Academic Lecture programme that seeks to give Year 10 - 12 pupils an insight into university-level research and study.
