John Guardiola's recent research centers on gastroenterology and endoscopy, with a particular focus on colonoscopy techniques and the detection and removal of colorectal polyps (small growths in the colon that can lead to cancer). The work also spans topics such as liver disease, transplantation outcomes, and endoscopic education. While the broader classification lists immunology topics, the published work is predominantly clinical gastroenterology.
Publication activity has grown sharply in recent years, rising from a few papers per year through 2023 to 12 in 2024 and 18 in 2025.
