Get To Know Me

I have dedicated my career to the surgical care of people with colon and rectal cancer, and am an expert in minimally invasive laparoscopic and robotic techniques for performing these surgeries.

In addition to having treated thousands of patients over the years, I have a keen interest in research, particularly in examining ways to improve outcomes for peoples with colon and rectal cancers. I have led National Cancer Institute–sponsored studies aimed at  improving the quality of life of patients with rectal cancer by performing smaller operations and identifying individuals  who might avoid surgery altogether through sufficient elimination of tumors with radiation therapy and chemotherapy.

I am also interested in identifying biomarkers that could predict rectal cancer response to radiation therapy and chemotherapy, and in examining racial disparities in outcomes for people with colorectal cancer.

I joined Memorial Sloan Kettering as Chief of the Colorectal Service in 2012, after serving in leadership positions at various institutions, including as chair of the Department of Surgery at the City of Hope in California and chief of the Section of Colon and Rectal Surgery at the University of California, San Francisco, Medical Center.

Over the course of my career, I have contributed to the wider medical knowledge of these cancers, having published more than 200 peer-reviewed publications, abstracts, editorials, and reviews. I have penned chapters for a spectrum of textbooks on surgical therapy for the myriad manifestations of colorectal disease, and also wrote a book for a patient audience titled Fast Facts – Colorectal Cancer (Health Press, 2010).

I have served as associate editor for such publications as Annals of Surgical Oncology, as co-editor of Diseases of the Colon and Rectum, and as an ad-hoc reviewer on a spectrum of journals including the Lancet Oncology and the Journal of Clinical Oncology.

I have lectured extensively on the advances in colorectal surgery both nationally and around the world, from grand rounds at the Johns Hopkins University School of Medicine to the Harvard Medical School Postgraduate Course in General Surgery. My participation in continuing medical education courses extends back to the mid-1990s, when I served as a lecturer on the principles of colon and rectal surgery at the University of Minnesota.

Outside of my clinical responsibilities, I am proud to have received various honorary memberships from professional societies over the years, and am a long-time member of the Research Foundation of the American Society of Colon and Rectal Surgeons. I have served as president of the organization since 2010.

I left my native country of Spain in 1985, after earning my medical degree and completing my surgery residency at the Complutense University in Madrid. I completed my training in general surgery at Harvard University’s Beth Israel Hospital and did a postdoctoral fellowship at Harvard Medical School. I also did a clinical fellowship in colorectal surgery at the University of Minnesota Medical Center.
