Care Philosophy: My goal, as a colon and rectal surgeon and as a surgical oncologist is to help my patients make informed decisions in their care and understand their disease process and treatment options, both surgical and non-surgical. I hope to help my patients find a better quality of life and to help them through their surgical experience (when necessary). I am lucky to work with a world renowned group of multidisciplinary specialists to help promote a multifaceted treatment plan for my patients, including radiation oncologists, medical oncologists, radiologists, pathologists, gastroenterologists, pelvic floor specialists, urologists, and interventional radiologists.

Biography: Dr. Emond is the Vice Chairman of Surgery at Columbia University. He has over 30 years of experience performing liver transplantation and complex liver and biliary surgery in children and adults, including the first living donor liver transplantation (LDLT) in the United States. Dr. Emond has published extensively in this field and was the co-chair of the NIH A2ALL program for 13 years. In collaboration with the department of Medicine at Columbia, Dr. Emond recruited the leadership of the Columbia Center for Translational immunology that created the foundation for translational and clinical research in transplantation tolerance. This will lead the way to inducing transplant tolerance in liver patients with the mixed chimerism strategy. As Director of Transplantation at the Columbia University Medical Center Dr. Emond's activities foster clinical excellence and research across all 11 of the solid organ transplant programs at the Medical Center. In recognition of his national and international leadership in transplantation, Dr. Emond is the past president of the American Society of Transplant Surgeons, the pre-eminent association of a transplant surgery. Contribution to Science Living donor liver transplantation Dr. Emond has spent a substantial portion of his career developing living donor liver transplantation and studying the safety of the procedure in both the donor and recipient. He participated in the first living donor liver transplant in the United States and focused on refining the techniques of performing living donor liver transplants and split liver transplants. He was the national co-chair of the NIH-sponsored Adult-to-Adult Living Donor Liver Transplantation (A2ALL) consortium from 2002 to 2015 to study the safety and outcomes of living donor liver transplants. Hepatic resection/ischemia Dr. Emond developed techniques for surgical resection of liver tumors and studied the effect of ischemia during resection on postoperative liver function. These studies include the outcomes of the extent of hepatectomy, the biochemical response to major hepatectomy and ischemia-reperfusion injury of the liver in rodent models. He has studied the clinical safety of inducing total vascular exclusion to provide a bloodless field during the liver transection. This has applications in both liver cancer and living donor hepatectomies. Hepatocellular carcinoma treatment Dr. Emond has studied many aspects of managing patients with hepatocellular carcinoma. These studies have included characterizing the risk factors for recurrence of disease following transplantation due to comorbidities and tumor characteristics. The research team has also studied the optimal method of preventing tumor growth in patients with HCC on the liver transplant wait list in addition to optimal strategies of liver allocation to optimize outcomes following liver transplantation. These studies have contributed to proposed changes in UNOS exception point allocation for liver transplant candidates with HCC. Pediatric liver transplantation Dr. Emond helped develop the field of pediatric liver transplantation. Contributions to this field include: the use of living donors for pediatric patients; use of auxiliary liver transplants for metabolic diseases; use of partial liver grafts for pediatric patients; and technical modifications that improved outcomes for this patient population.

Care Philosophy: I am a medical oncologist dedicated to treating and studying diseases that affect the genitourinary system. At Weill Cornell Medicine, I work at the intersection of science and patient care, which allows me to combine my medical training and research insights to provide the best possible care to adults with kidney, bladder, prostate and testicular cancers. It is a priority of mine to not only deliver cutting-edge and compassionate care to my patients, but to enhance the quality of life for patients and their families as they cope with a cancer diagnosis. I feel privileged to collaborate with a multidisciplinary, world-class team of clinicians, nurses, social workers and other cancer sub-specialists. Together, we are able to offer an extraordinary level of expertise and support to our patients at all stages of disease. Additionally, my scientific work involves translational research and clinical trials to investigate promising, new treatment therapies. This allows us to move the field forward in order to one day find cures for cancer.
