Assistant Professor at the University of Maryland School of Medicine

Artificial intelligence, or the use of machine learning algorithms and deep learning software to mimic human cognition or rationality, has become the backbone of many of our daily activities. Today, the application of artificial intelligence (AI) for the analysis of health data is increasing, especially in the fields of precision medicine, diagnosis and patient monitoring. These technologies have the potential to revolutionize patient care and disrupt the processes of healthcare organizations. But what can we expect as these technologies are implemented in the fields of health and medicine, which have been rooted in human contact?

In this discussion, Dr. Austin Chiang, chief medical officer of Medtronic Gastroenterology, the first company to release AI software for colonoscopy, and Professor Andrew Laine of Columbia University, who studies the mathematical analysis of diagnosis computer-assisted, explore the state of the field, ethical considerations/pitfalls, and impact on patient care.

Time will be allocated for questions and answers.


Andrew F. Laine is the director of the Heffner Biomedical Imaging Lab at Columbia, where he focuses on mathematical analysis and quantification of medical images, signal and image processing, computer-aided diagnosis, and biomedical informatics. imagery. His work is based on the imaging of structures at the levels of molecular, cellular, tissue and organ analysis. The goal is to develop biomedical technology for unmet clinical needs and transform that technology into commercial products that will improve healthcare and save lives.

Laine was the first to use “wavelet” multi-scale representation to enhance the subtle details of mammograms. Today, the algorithm he developed in 1992 is used in almost all commercial digital mammography systems. Currently, Laine is applying multi-resolution wavelet techniques to classify pulmonary emphysema. He is also collaborating on a medical informatics project to enable clinicians to better diagnose a patient using both text and annotated results from medical images. Laine’s work draws on techniques such as time-frequency decompositions/representations, speckle tracking, texture analysis, machine and deep learning, variational segmentation, deformable parametric models, and reconstructions. pictures.

Laine earned a BS in Biological Sciences from Cornell University in 1977, an MS in Chemistry from the University of Connecticut in 1980, and a DSc in Computer Science from Washington University, St. Louis, in 1989. He is a Fellow of the Institute of Electrical and Electronics Engineers and the International Federation of Medical and Biological Engineering. He is also a Fellow of the Data Science Institute at Columbia.


Austin Chang is an Ivy Triple League Graduate Gastroenterologist and Advanced Endoscopist (Harvard, Colombia). In October 2021, he became the first Chief Medical Officer of the gastrointestinal business of Medtronic, the world’s leading medical device company responsible for products such as Barrx radiofrequency ablation devices, capsule endoscopy products Pillcam, EndoFLIP, Bravo, Sharkcore and GI Genius are the first-to-market AI-assisted polyp detection device to help endoscopists better prevent colon cancer. Dr. Chiang’s interests include new endoscopic weight loss treatments as well as complex interventional endoscopic procedures, including the diagnosis and treatment of various gastrointestinal conditions and their complications. These include a variety of cancers affecting the gastrointestinal tract such as cancers of the pancreas, bile duct, esophagus, stomach, colon and liver.

Dr. Chiang is currently Assistant Professor of Medicine at Jefferson Health (Thomas Jefferson University Hospitals) in Philadelphia, Pennsylvania, and is Director of the Endoscopic Weight Loss Program and Medical Director of Social Media for the Health System. He is fully licensed and accredited in the states of Pennsylvania and Massachusetts. Having trained in the only program dedicated to bariatric endoscopy, he is one of the few doctors trained in advanced endoscopy with triple certification in the world. His triple certifications include Internal Medicine and Gastroenterology by the American Board of Internal Medicine, and Obesity Medicine by the American Board of Obesity Medicine.


Frances Onyimba MD is a gastroenterologist at WellSpan Digestive Health focusing on creating multidisciplinary and specialized programs for the foregut. Previously, she worked at the University of Maryland Medical Center treating patients with esophageal diseases and gastrointestinal motility disorders. She completed her medical school at Columbia University College of Physicians and Surgeons before completing her residency in internal medicine and a fellowship in gastrointestinal motility and neurogastroenterology at Johns Hopkins Hospital. She then completed her General GI Fellowship at the University of California, San Diego, where she served as Chief Fellow. In 2019, she was selected into the American College of Gastroenterology’s Young Physician Leadership Scholars Program for Physician Leadership Development and Advocacy. His interests include health communications and innovative health care programs and practices.
