Throughout his career, the multidisciplinary clinical and research teams he has led have produced substantial clinically focused evidence to redefine the scale of problems caused by GI consequences of cancer therapies, why they occur, and the best approaches to prevent and treat these conditions.
Charlotte Beardmore, FCR MBA BSc(Hons) DCR(R&T) is Director of Professional Policy at the Society and College of Radiographers.
Dr Jan Bornschein, MD, PhD, Consultant Gastroenterologist at Oxford University Hospitals NHS Foundation Trust, and Honorary Senior Clinical Lecturer at the University of Oxford, Medical Sciences Division.
Dr Bornschein completed his medical training in Magdeburg, Germany, with an early focus on gastrointestinal oncology. He managed the Oncology Outpatients Department there, overseeing the prescription and administration of systemic therapy for cancer patients.
In 2013, he moved to the UK to undertake a Post-Doctoral project at the MRC Cancer Unit, University of Cambridge, exploring the characteristics of cancer at the gastro-oesophageal junction.
