Biography
Uwe Fischer, MD, PhD, is an Assistant Professor of Surgery in the Division of Vascular Surgery at Yale School of Medicine. He is board-certified in general and vascular surgery and practices at Lawrence + Memorial Hospital, Westerly Hospital, and affiliated clinical locations. His clinical expertise includes aortic and peripheral vascular disease, carotid disease, endovascular interventions, dialysis access, and limb preservation.
In addition to his clinical practice, Dr. Fischer's academic work focuses on the implementation of artificial intelligence in healthcare. His research examines the institutional, organizational, and operational factors that determine whether AI technologies can be successfully integrated into clinical practice. His particular interests include institutional absorption capacity, AI–institution compatibility, clinical workflow integration, governance, accountability, and the transferability of AI technologies across healthcare organizations and international healthcare systems. He is developing approaches to prospective AI implementation assessment, including the potential use of operational simulation to evaluate deployment conditions before implementation.
Dr. Fischer has contributed to research on AI-supported aortic disease surveillance and clinical workflow integration. He presented his work on healthcare AI implementation at the University of Cambridge in July 2026 and participated in an Alexander von Humboldt Foundation Dialogue on AI implementation and governance in October 2026. He is preparing a monograph on the institutional architecture of artificial intelligence in healthcare for Oxford University Press, with publication anticipated in 2027.
He received his medical and doctoral degrees from Johannes Gutenberg University Mainz, Germany, completed general surgery residency training at the University of Texas Health Science Center at Houston, and subsequently completed a fellowship in vascular and endovascular surgery at Houston Methodist Hospital.

Overview
Healthcare Artificial Intelligence Implementation and Institutional Compatibility
My research focuses on the implementation of artificial intelligence in healthcare, particularly the organizational, clinical, operational, and governance conditions that determine whether AI technologies can be successfully integrated into routine medical practice.
A central theme of my work is institutional absorption capacity: the ability of a healthcare organization to accommodate the new demands, decisions, responsibilities, and workflows introduced by AI systems. Technical validation alone does not establish whether an AI application can be effectively deployed within a particular institution. Successful implementation also depends on institutional resources, workflow compatibility, clinical accountability, governance structures, and the alignment of anticipated benefits with operational capabilities.
My current research examines the development of systematic approaches to AI–institution compatibility assessment, with the objective of evaluating deployment feasibility before implementation. This includes exploring simulation-based methods to identify potential operational bottlenecks, estimate resource requirements, compare alternative deployment configurations, and inform decisions to deploy, modify, defer, or decline specific AI applications.
An additional area of interest is the transferability of healthcare AI across institutions and healthcare systems. An AI application successfully implemented in one environment may encounter fundamentally different operational, regulatory, financial, and organizational conditions elsewhere. Understanding these differences is essential for responsible implementation and international adoption.
My clinical AI research includes the evaluation of AI-supported aortic disease surveillance and management workflows. This experience informs my broader work on the translation of AI technologies from technical validation to sustainable clinical operations.
I have presented this work internationally, including at the University of Cambridge in July 2026 and in an Alexander von Humboldt Foundation Dialogue in October 2026. A forthcoming Oxford University Press monograph, scheduled for publication in 2027, addresses the institutional architecture and challenges of healthcare AI implementation.
The overarching objective of my research is to develop evidence-based methods that help healthcare organizations determine not simply whether an AI system performs adequately, but whether it can be implemented effectively, safely, and sustainably within their specific institutional environment.

Clinical Care
Overview
Uwe Fischer, MD, is a vascular surgeon who specializes in the entire spectrum of vascular problems. He cares for patients at Westerly Hospital in Rhode Island, and Lawrence and Memorial Hospital in New London, among other locations. He works closely with colleagues at Yale New Haven Hospital, where he performs complex procedures in a hybrid operating room. He is also a specialist in the interpretation of vascular laboratory studies.
He treats patients for a variety of vascular conditions, including aneurysms, carotid disease, peripheral arterial disease, varicose veins, and lower extremity limb preservation.
Dr. Fischer, who went to medical school in Germany, says it was always his dream to be a physician. Now he finds the most rewarding part of his work to be forming trustful relationships with patients. “My goal is always to form treatment partnerships with my patients and address all medical issues, and combat difficult tasks such as smoking cessation and compliance with treatment plans,” he says. “I am always available to my patients over the phone. This is one of my passions—to bypass any frustrating wait times and multiple steps to get an answer from me.”
Dr. Fischer started using telehealth long before the COVID-19 pandemic to provide easy access to care for patients, whether that involved follow-up visits after a procedure, discussion of test results, or consultations to answer their questions. In addition to his clinical work, he is a researcher interested in the impact of community outreach and telehealth on vascular care.
