Eugene Choi might not be a household name, but his legacy as a pioneering Korean-American gastroenterologist who helped shape modern endoscopic techniques is undeniable. His work in the 1970s and 1980s laid the foundation for many of the minimally invasive procedures we now take for granted — from colonoscopies to endoscopic ultrasounds.

While he may not have sought fame, his influence continues to ripple through modern medicine. Today, a new generation of physicians and researchers are building on his work, carrying his torch into the future of gastroenterology.

Here are five contemporary figures who are continuing and expanding upon Eugene Choi’s legacy.

1. Dr. Shailen D. Puli — Innovator in Endoscopic Ultrasound

Dr. Shailen D. Puli is a name that comes up often when talking about the cutting edge of endoscopic ultrasound (EUS). His groundbreaking work in refining EUS-guided biopsies has improved diagnostic accuracy for pancreatic diseases — a field that Eugene Choi helped bring into focus decades ago.

What I find especially compelling about Dr. Puli is how he blends precision with compassion. He’s not just focused on the technical side of procedures — he’s also published extensively on patient outcomes and comfort. In many ways, he represents the next evolution of Choi’s philosophy: medicine that’s both scientifically rigorous and deeply human.

2. Dr. Amrita Sethi — Champion of Early Detection

Dr. Amrita Sethi, a gastroenterologist at Columbia University, has become a leading voice in early cancer detection through endoscopy. Her research into real-time optical biopsies mirrors the kind of forward-thinking that defined Eugene Choi’s career.

I remember reading a piece she wrote about using AI-assisted endoscopy to detect Barrett’s esophagus. It struck me how her approach — marrying technology with clinical insight — reflects the same spirit that Choi had when he first began experimenting with early endoscopic tools.

3. Dr. David A. Schwartz — Educator and Global Advocate

Dr. David A. Schwartz has taken a different but equally important path — he’s become a global educator in endoscopic techniques, particularly in underserved regions. As someone who has trained physicians across Africa and Asia, he’s ensuring that Choi’s innovations aren’t limited to high-tech hospitals in major cities.

In a field that can sometimes feel dominated by high-tech gadgetry, Schwartz reminds us of the fundamental mission: bringing life-saving care to as many people as possible. That’s a mission Eugene Choi believed in deeply.

4. Dr. Linda S. Lee — Patient Advocate and Researcher

Dr. Linda S. Lee is a rising star in the world of functional gastrointestinal disorders. Her work with conditions like irritable bowel syndrome (IBS) and motility disorders expands the scope of gastroenterology beyond procedures and into the realm of patient experience.

What’s especially impressive is her dual focus: she’s not only conducting clinical trials but also working directly with patients to improve quality of life. In that sense, she’s carrying forward Choi’s legacy by emphasizing that the ultimate goal of medicine is not just diagnosis and treatment — it’s healing.

5. Dr. Douglas K. Rex — Authority on Colonoscopy Standards

Dr. Douglas K. Rex is often referred to as one of the foremost experts on colonoscopy. He’s been instrumental in setting standards for quality and safety — something that Eugene Choi would have appreciated, given his meticulous approach to endoscopic practice.

I’ve followed Dr. Rex’s work for years, and what stands out is his commitment to continuous improvement. He’s not content with the status quo — just like Choi wasn’t when he first began refining endoscopic techniques back in the 1970s.

Each of these five figures is pushing gastroenterology forward in their own way, but they all share a common thread: they’re building on the foundations laid by pioneers like Eugene Choi. Their work reminds us that progress in medicine isn’t just about big breakthroughs — it’s also about steady, thoughtful innovation.
