About Gary Bass

Following Bachelors (2001) and Masters (2003) degrees in Physiology at University College Dublin, in Ireland, Dr. Bass completed medical school at the Royal College of Surgeons in Ireland (2008).

Dr. Bass completed the general surgery residency programme at the Royal College of Surgeons in Ireland in 2020, and is European (FEBS) board-certified in General & Emergency Surgery.

He also completed a Masters degree in Business Administration from the Quantic School of Business, Washington DC and the Certificate in Clinical Epidemiology and Biostatistics (CCEB) from the University of Pennsylvania. He is currently enrolled as a PhD candidate in Surgical Sciences at Orebro University in Sweden where he is studying practice patterns and outcomes in complicated biliary calculous disease under Assoc Prof Shahin Mohseni.

He has published over 60 peer-reviewed articles and has been cited over 1500 times.

He is an ATLS Instructor and an Instructor in the Modular Ultrasound for Surgeons Course (MUSEC), and has served on the Emergency Surgery and Visceral Trauma Committees of the European Society for Trauma and Emergency Surgery, the Multi Institutional Trials Committee of the American Association for the Surgery of Trauma (AAST) and the Manuscript and Literature Review Committee of the Eastern Association for the Surgery of Trauma (EAST).

He is married to Anesthesiologist and Human Factors in Patient Safety expert Dr. Caoimhe Duffy and has 3 boys.

Dr. Bass completed a Surgical Critical Care Fellowship at the University of Pennsylvania in Philadelphia, USA, where he is now pursuing a second fellowship, in Trauma and Emergency Surgery. He hopes to continue his clinical and academic interests in trauma, emergency general surgery and surgical critical care and in surgical outcomes research. He is looking forward to a career in academic Trauma Surgery and Surgical Critical Care.
