• Member of the European Society of Pediatric Endoscopic Surgeons 

The research activity of Ioannis Georgopoulos focuses on bridging basic science with clinical pediatric surgical practice, as well as on clinically applied research, aiming at the continuous improvement of pediatric surgical care through scientifically documented and innovative approaches. His doctoral work at the National and Kapodistrian University of Athens investigated the role of mechanical factors, particularly intestinal stenosis, in shaping the inflammatory response and disease progression of Crohn’s disease in experimental models, contributing to the understanding of mechanisms influencing surgical strategy in complex inflammatory bowel diseases.

In parallel, his clinical research focuses on the evaluation and development of minimally invasive techniques in pediatric surgery, including laparoscopic gastrostomies, management of obstructive gastrointestinal diseases, and selected congenital anomalies. This work has been presented at international conferences and published in peer-reviewed international journals, contributing to the dissemination of practices that reduce surgical trauma, accelerate recovery, and improve long-term outcomes for children and their families.

Within the framework of his research activity, he has served as an elected member of the Scientific Council of the General Children’s Hospital of Athens “Aghia Sophia” (2018–2021). He actively participates in the design, implementation, and supervision of numerous clinical research studies conducted annually at the same institution, which are published in international journals and/or presented at national and international scientific conferences. He has also contributed to the supervision of four doctoral dissertations in the field of Surgery and Pediatric Surgery at the National and Kapodistrian University of Athens and the University of Patras.

At the same time, he actively collaborates and co-authors joint research projects with internationally renowned Pediatric Surgeons such as Mario Lima (Bologna, Italy), Sameh Shehata (Alexandria, Egypt), and Dariuz Patkowski (Worklaw, Poland).

Finally, Dr. Georgopoulos serves as a reviewer for distinquished international journals such as Digestive Diseases and Sciences, The American Journal of Case Reports, Scientific Reports (Springer Nature), Frontiers in Medicine, Frontiers in Pediatrics, among others.
