Research Interest

Dr. Gregersen is currently Professor and Chief of the Bioengineering Division in the Department of Surgery, the Chinese University of Hong Kong. He is educated in Denmark and received the MD and PhD (Dr.m.sci.) degrees from Aarhus University in 1988 and 1994. Furthermore, Professor Gregersen has a master degree in administration and strategic leadership and attended leadership courses at INSEAD and at the Institute of Directors (UK).

Previously Dr. Gregersen worked at universities in Denmark, Norway, Ireland, USA and China as professor in gastrointestinal physiology, bioengineering, biomechanics and medical device innovation. Dr. Gregersen served as the executive director of the Sino-Danish University and vice-Dean at the University of the Chinese Academy of Sciences (UCAS) in Beijing from 2010 to 2013.

Professor Gregersen established the Mech-Sense Center in 2003, the Idea Clinic at Aalborg Hospital (Denmark) in 2008, and the GIOME in 2012. The GIOME has its headquarter at the Chinese University of Hong Kong and in Prince of Wales Hospital in Hong Kong, and research sites at Chongqing University in China, the GIOME Academy at Aarhus University in Denmark and at California Medical Innovations Institute in California. The GIOME project is a multi-centric, integrated program to design, develop, implement, test, document, archive and disseminate quantitative information and integrative models of the functional behavior of the GI tract ( The GIOME describes the physiological dynamics of the normal intact GI tract and is built upon interdisciplinary approaches with application to GI diseases. There is a special focus on development of new medical devices and technologies including computational models

Dr. Gregersen is active in interdisciplinary research collaboration and has a large international network. He published several books on gastrointestinal function and biomechanics. He contributed several innovations from his research among them the commercialized EndoFLIP device and the multimodal technology for pain diagnosis. Other inventions are the Fecobionics expulsion test and the Fungibionics obesity therapy.

Professor Gregersen has among other awards received the Walton Award named after Nobel Laureate in physics E.T.S Walton (Ireland 2008), the American Gastroenterology Association Award (2009), the Special Recruited Foreign Expert Award (China 2013), and the National Friendship Award (China 2014). He became Fellow of the American Gastroenterology Association in 2018 (AGAF).
