University of North Carolina at Chapel Hill

I focus on enhancing existing care processes and models – while developing new ones – that support the Department of Medicine’s 600+ clinicians and that better meet the needs of the various populations they serve. www.med.unc.edu/medicine

Vice Chair, Department of Medicine

I care for adults with acute and chronic GI conditions in inpatient, outpatient, and procedural settings. Clinically, I focus on functional GI and motility disorders, and have served as site-PI for 20+ clinical trials and co-authored national constipation practice guidelines. I write and present on topics related to care delivery.

Professor of Medicine

I am a member of a physician team that works to optimize how we use the EPIC electronic health record. I co-developed applications to improve scheduling for open access endoscopy and for communicating test results. I am broadly interested in using digital health technologies to solve real problems.

Lead Informatics Physician

I present on topics related to digital health and clinical administration.

Adjunct Associate Professor of Health Policy and Management

I led and managed a premier academic practice of 50+ clinicians who care for adults with a full spectrum of GI and liver conditions in multiple endoscopy units, outpatient clinics, and UNC Hospital inpatient units. www.uncgastro.com

Vice Chief, Gastroenterology

I received an NIH K12 Career Development Award to develop an integrated, web-based program for IBS self-care. I conducted health services research on topics related to functional GI disorders and gastroenterology practice.

Assistant & Associate Professor of Medicine

Fellow in Gastroenterology

Brigham and Women's Hospital / Harvard Medical School

Internal Medicine Resident

I am a gastroenterologist, physician leader, clinical operator, academic, thought leader, and advisor.

I literally work in the belly of the healthcare beast!

I am experienced at caring for adults across various settings, building and managing clinical programs, implementing digital health solutions, performing clinical research, and explaining how healthcare works and can work better.

I believe healthcare is ultimately about organizing and supporting people to care for themselves and others. That the best care integrates body and mind. And that we must harness digital technology in ways that facilitate compassionate healing.

My mission is to support and improve care in ways that benefit all. I am particularly excited by opportunities to redesign specialty care to be more accessible, affordable, pleasant, effective, and sustainable.

I love meeting people and welcome opportunities to learn and share perspectives, serve as an advisor, and collaborate on meaningful and impactful work. Please contact me via InMail.

Because LLMs are unreliable, I struggle to see how (or why) we will use them for clinical tasks that matter. This fantastic interview helped me see things more clearly. 

Francois Chollet explains that LLMs are memorization and pattern matching machines. While this is quite useful, it is not the same as intelligence, which he defines as “the ability to adapt to an ever-changing world.”

(Piaget similarly defined intelligence as “what you use when you don’t know what to do”).

Because memorization and pattern matching are limited, Francois argues for hybrid systems that merge LLMs/deep learning with other approaches (e.g., discrete program search) to, in essence, mirror what Kahneman described as System 1- and System 2-type thinking.

I'll let the real computer scientists elaborate or tell me why this is wrong. 

To me, the point is that if we ever broadly use LLMs for clinical tasks where errors matter, they will likely be combined with other types of AI. (Other leading computer scientists like Stephen Wolfram also argue for this).
