Bader Alfares is a Physician Scientist at the University of Groningen's School of Medical Sciences, Department of Pediatric Surgery, specializing in complications of pediatric liver transplantation. His research focuses on vascular complications, particularly portal vein obstruction and stenosis management.

Research interests center on pediatric transplant surgery with emphasis on:

• Portal vein obstruction pathophysiology and treatment
• Systematic review methodology in transplantation
• International registry development (PORTAL registry)
• Vascular complication diagnostics
• Postoperative management protocols

His work bridges clinical practice and evidence-based guidelines through large-scale collaborative studies.

Publication trends show consistent focus on portal vein complications since 2019, evolving from case reports to systematic reviews and international registry protocols. Key themes include treatment efficacy assessment, diagnostic standardization, and global management practice comparisons across 50+ institutions.

Academic contributions include:

• Principal investigator for PORTAL registry protocol (2023)
• Lead author on 2 systematic reviews (2021, 2025)
• Co-investigator on international management practice analysis (2025)

Research leadership involves coordinating multicenter collaborations across 12 countries, with co-authorship including major transplant centers in Europe, Asia, and the Americas. His work directly informs clinical guidelines through registry-based evidence generation.
