Peter Siersema

Peter Siersema is a Full Professor in the Department of Gastroenterology & Hepatology at Erasmus MC, a leading academic medical center in the Netherlands. His work bridges clinical gastroenterology with innovative diagnostic technologies, particularly in the fields of gastrointestinal oncology and endoscopic interventions.

Research Interests: His primary research areas include colonoscopy, colorectal cancer, esophageal adenocarcinoma, endoscopic retrograde cholangiopancreatography (ERCP), and the application of electronic nose technology for non-invasive cancer detection. He investigates alarm symptoms in young patients with suspected upper GI cancers and evaluates metabolic outcomes of endoscopic bariatric procedures.

Recent Research Trends: Analysis of his most recent publications reveals a strong focus on methodological rigor in diagnostic studies, particularly in validating breath-based biomarkers for colorectal cancer. He also contributes to systematic reviews on endoscopic treatments for type 2 diabetes and cohort studies on polyp recurrence after endoscopic resection—highlighting his commitment to evidence-based gastroenterology.

Supervision and Collaboration: He has supervised at least 10 junior researchers or students. His collaborative network spans multiple institutions, with recent external collaborations across international boundaries, particularly in breath analysis and gastrointestinal oncology research.
