President-Elect - Simon Law

Simon Law
The University of Hong Kong, China







I have been an active member of ISDE since the early 1990s, and have attended all its congresses since. As an esophageal surgeon, I have special affinity for the society, as my career grew parallel with it. My closer association with ISDE commenced when I became an editor of Diseases of the Esophagus in 1999, and associate editor since 2010. I have served as co-chairman of the scientific committee for the ISDE world congress in Vancouver in 2014. Currently I am co-chairman of the Education Committee. I have been actively involved in development of many international initiatives on esophageal surgery, including as member of the Worldwide Esophageal Cancer Collaboration, Esophageal Complication Consensus Group, and working group on Enhanced Recovery after Esophagectomy. Engaging with other societies, I also hold positions, such as Consultant for International Society of Digestive Surgery, National Delegate to the International Surgical Society, Secretary General of the American College of Surgeons (Hong Kong Chapter), Asia II Representative of the Member Services Committee of the Society for Surgeons of the Alimentary Tract (SSAT). In addition I am honorary member of the American Surgical Association as well as European Surgical Association. Residing in Hong Kong, I have extensive network with physicians from the Asia Pacific region, not just in countries traditionally with close association with ISDE (such as Japan), but particularly in China, where growing involvement is evident in recent years. I hope that with my experience in the society, my international involvement, my network, I can continue to serve ISDE and form bridges between East and West. I am humbled by the achievement of the ISDE, and will be honoured to contribute more to the society in the future.

I also lead the Royal Australasian College of Surgeons’ Clinical Trials Network Australia and New Zealand (CTANZ) as its Clinical Director, an initiative to enhance research capacity by supporting the development of trainee research collaboratives, and trainee led multicenter clinical trials across Australia and New Zealand.

Vice President - Nicholas J. Shaheen

Nicholas J. Shaheen
University of North Carolina, USA





I am a gastroenterologist and professor of medicine at the University of North Carolina School of Medicine, and Chief of the Division of Gastroenterology and Hepatology at UNC. I specialize in endoscopic treatment of precancerous and cancerous conditions of the esophagus, and am an active clinical researcher in these areas. I am a longstanding member of the ISDE and support its mission. The unique multidisciplinary and international nature of the group provides a perspective not found elsewhere, and leads to enriched and stimulating academic interaction. I have enjoyed serving as a co-chair of the planning committee for our upcoming virtual Congress, and addressing the challenges presented by mounting a meeting in the time of a pandemic.

I have extensive administrative experience, both at my institution and in professional organizations, which make me well-suited for this position. In addition to managing our GI division and the clinical research center here at UNC, I have served as the Director of the American College of Gastroenterology Institute, the research and education arm of the ACG. I have also been a trustee of that organization for the past decade. I also served the American Gastroenterological Association as head of the Clinical Practice section, and a member of AGA Council. I am highly collaborative and believe that the best ideas to engage a professional society usually originate from the membership up, not the leadership down. I am honored to be elected in this position, and will work hard to promote the ISDE in national and international venues.

I am honored to be the Vice President of International Society of Disease of the Esophagus. I have been an active member of ISDE since the early 1990s, and have attended all its congresses since. As an esophageal surgeon, I have special affinity for the society, as my career grew parallel with it.

Secretary - Gail Darling

Gail Darling
Toronto General Hospital, University Health Network, Canada






I have devoted my career to esophageal diseases both benign and malignant, both in my clinical practice and in research. I am committed to advancement of the diagnosis and management of esophageal disease, particularly esophageal cancer. I support the mission of the ISDE. The importance of a society devoted to diseases of the esophagus cannot be understated. Esophageal disease does not receive sufficient focus within other societies focussed on digestive diseases in general, cancer, or procedure based societies such as surgical societies. ISDE is important not only because of its focus on esophageal disease but also its multidisciplinary nature which brings together specialists of all disciplines whose interest and focus is esophageal disease. Not only does this promote advances in diagnosis and management but also scholarly activity and collegiality.

As a long standing member of ISDE, I believe I am well suited to the duties and obligations of secretary. I have good written and oral communication skills and a collaborative leadership style. I am particularly interested in increasing membership, and promoting interaction with other societies whose mission is aligned with ISDE. I believe that working together we can advance.


Treasurer - Gary Falk

Gary Falk
University of Pennsylvania Perelman School of Medicine
Philadelphia, PA

Gary W. Falk, MD, MS, AGAF, is currently professor of medicine and co-director, GI Motility/Physiology Laboratory at the Hospital of the University of Pennsylvania. Dr. Falk received his under graduate and medical school training at the University of Rochester, NY, before going to George Washington University, Washington, DC, for his medical internship and residency. After a clinical and research fellowship at the University of Michigan, Ann Arbor, he was a member of the Department of Gastroenterology and hepatology at the Cleveland Clinic, OH, for more than 23 years where he was director for the Swallowing and Esophageal Center. While in Cleveland, he also received a master’s degree in clinical research from Case Western Reserve University.

He has been involved in clinical research in Barrett’s esophagus, gastroesophageal reflux disease, Helicobacter pylori, esophageal motility disorders, advanced esophageal imaging and therapeutics, and eosinophilic esophagitis that has resulted in over 150 peer reviewed publications and NIH and non-NIH grants. The most important of these themes has been in the area of early detection and prevention of esophageal cancer. Among the contributions of his research group have been a number of publications on the significance of high-grade dysplasia in Barrett’s esophagus, including biopsy forceps yield and findings of unsuspected cancer at esophagectomy, the use of cytologic sampling as an alternative to biopsy based surveillance, and the development of the concept of cytology specimens as a platform for molecular based biomarker studies. Other studies in Barrett’s esophagus have focused on epidemiologic observations related to the role of H. pylori in the disease along with issues of age and gender in the development of cancer. Collaborations with other centers have led to studies on familial risk, molecular imaging paradigms, chemoprevention, radiofrequency ablation and endomicroscopy. He has recently served as the chair of an NCI multicenter chemoprevention study examining the role of high dose proton pump inhibitor therapy in Barrett’s esophagus. He is involved in other chemoprevention trials in the NCI-funded Cancer Prevention Network. Recently, translational research studies in collaboration with basic scientists in cancer biology and pathobiology have commenced in order to study the role of inflammatory mediators in eosinophilic esophagitis and cell of origin of Barrett’s esophagus. Research in eosinophilic esophagitis is now focusing on clinical trials of novel therapeutic agents, clinical and biologic aspects of pediatric to adult transition, and participation in the Consortium of Eosinophilic Gastrointestinal Disease Researchers consortium.

Dr. Falk has served nationally through professional societies, including being a past-president of ASGE, editorial positions at journals and on grant review committees at NIH. He is a past associate editor of the American Journal of Gastroenterology and is the current editor of AGA Perspectives. He is a recipient of the Sidney Cohen University of Pennsylvania GI Fellowship Teacher of the Year Award on two occasions, AGA Distinguished Clinician Award, and AGA Imaging & Advanced Technology Section Research Mentor Award.

Vanderbilt University Medical Center, USA











The International Society for Diseases of the Esophagus (ISDE) helps disseminate to its membership and beyond important and clinically relevant information about esophageal diseases. ISDE for years has advocated scientific exchange of knowledge relating to esophagus among multidisciplinary specialties. I am honored to have been nominated as a Director in ISDE. I am committed to the mission of the Society in order to advance the practice of gastroenterology and to significantly impact in digestive disease health and outcomes. Over the past years, I have had the privilege to serve at various capacities in different GI organizations and I am currently an associated editor of Gastroenterology. I will provide the requisite support for the missions of the ISDE and provide any insight into improving upon the educational and scientific mission of the Society. My experience (academic position, research, publication, mentoring and interactions with various societies) has given me greater appreciation for the importance of Societal function as well as the future direction of the Society as a whole. I have always sought to enhance the quality of clinical care, education, advocacy and research that impact our ability as gastroenterologists to improve health and prevent disease.

I view the role of the ISDE Director highly important to ensure continued successes in all aspects of ISDE endeavors. I am grateful for being elected and I accept this nomination with humility, sense of pride and commitment to fulfill this important responsibility on behalf of the ISDE. I would work closely with other members to ensure the goals of this society are met and we continue to strive forward in providing significant contributions to our organization. If selected, I will take on this responsibility with enthusiasm, dedication and humility. I have the requisite time to fully commit to this position and would welcome the opportunity. My commitment and service to the ISDE will continue to be strong and I look forward to my continued stewardship on behalf of patients, members and the ISDE.

Long-Qi Chen

Long-Qi Chen
West China Hospital, China






Being an active member of ISDE since 1994, I attended most of the ISDE conferences since 1998. It was a significant experience for me to witness the growing and strengthening of ISDE, now to be the most representative and impacted societies in the world. As for China, I founded Chinese Society for Diseases of the Esophagus (CSDE) in 2015 in order to improve the current unsatisfactory quality of medical care. The Society is focused on improving the medical service quality by enhancing medical education and training, bridging international collaboration and coordinate clinical studies.

As one of the 2 affiliated societies to ISDE, CSDE represents a combined initiative amongst Chinese surgeons, physicians, pathologists and scientists to study esophageal diseases. Later on, we promoted over 120 abstracts submission and 90 attendees to ISDE 2016 in Singapore. It would be the similar expectation for ISDE 2018 in Vienna. What’s more, the “CSDE Annual Working Conference 2020 ” was successfully held in Shenzhen, China. It brought together multiple specialties focused on the clinical management and research of patients with esophageal diseases. Since its inception, CSDE has been playing as an excellent platform for the academic exchange of clinical and scientific knowledge on the latest developments.

I am willing to initiate or chair some task forces assigned by ISDE, already with experience with being enrolled in the WECC task force to define the 7th and 8th edition of TNM staging for esophageal cancer. I am keeping communication and also serving in other local relevant societies in China like Esophageal Cancer Committee, Chinese Anti-Cancer Association (CACA), and Esophageal Expertise Committee, Chinese Association for Thoracic Surgeons (CATS).

Magnus Nilsson

Magnus Nilsson
Karolinska Institutet, Sweden







I am professor of surgery and head of the Division of Surgery at the Department of Clinical Science, Intervention and Technology at Karolinska Institutet in Stockholm, Sweden.

My clinical work is mainly dedicated to esophageal and gastric cancer surgery, but I also do quite a bit of benign esophageal work, including hiatal hernia repair and management of esophageal perforations and airway fistulas. My main scientific interests are oriented towards optimizing management of esophageal cancer patients, with a particular interest in neoadjuvant therapies and tailoring of lymphadenectomy and minimally invasive surgical techniques.

I am the past President of the European Society for Diseases of the Esophagus, the Swedish Society of Upper Abdominal Surgery and currently the Chairman of the Swedish National Registry for Gastric and Esophageal Cancer. I have a particular interest in multidisciplinary collaboration, and I am much involved in several oncological associations, for example as a faculty member of the upper gastrointestinal group of the European Society for Medical Oncology (ESMO) and a member of the European Organization for Research and Treatment of Cancer (EORTC) gastrointestinal group. As a result of many years of multidisciplinary collaboration I have led and currently lead some international randomized multicenter trials in the crossroads of surgery and oncology, such as the completed NeoRes I and II trials and the currently ongoing NEEDS trial.

I am also an associate editor of Diseases of the Esophagus since 2015 and the work with our great journal is something that I consider extremely important and always try to prioritize. I will work hard to further develop multidisciplinary and international collaboration in the interests of the ISDE.
