About

I am an academic vascular surgeon whose work focuses on developing cost-effective, resilient, and equitable strategies to prevent leg amputations..

My clinical practice is based at the Michael E. DeBakey Veterans Affairs Medical Center in Houston, where I care primarily for patients with advanced peripheral artery disease / critical limb-threatening ischemia. Over the course of my career, I have performed nearly 4,000 operations, with a particular emphasis on limb salvage bypass operations.

I serve as Service Line Chief for Vascular Surgery at the DeBakey VA Medical Center and as Program Director of Baylor College of Medicine’s vascular surgery fellowship. Much of my work has involved bringing different specialties together, reducing delays and waste, developing practical clinical guidance, and improving the education of students, residents, and fellows.

My academic work includes more than 150 peer-reviewed publications spanning limb salvage, vascular outcomes, health economics, clinical trials, and the organization of vascular care. I ask practical research questions that will have impact on my own daily clinical practice.

All illustrations and scientific figures on this site are my original work. Illustrations were created using open-source vector and raster graphics tools, while scientific figures were produced using statistical programming and analysis software. No generative AI was used in their creation.
