Dr. Alan Dardik is a surgeon-scientist who seeks to use the power of molecular biology to achieve a modern understanding of vascular disease, and to use the basic science laboratory to perform cutting edge research to ultimately benefit patients with vascular disease. Dr. Dardik trained at Yale, the University of Pennsylvania, and the Johns Hopkins Hospital before his appointment to the Yale faculty in 2001. Dr. Dardik concentrates his clinical practice in vascular surgery at the VA Connecticut where he is the Chief of the Vascular Surgery section, focusing his practice on teaching of medical students, residents, and fellows.

Dr. Dardik is currently the Vice-President of the International Society for Vascular Surgery and the Recorder for the Association of VA Surgeons.

The Dardik laboratory studies the healing and function of blood vessels and synthetic blood vessel substitutes that are used in patients having vascular bypass surgery. We are currently trying to understand the fundamental molecular mechanisms by which vein graft adaptation results in positive remodeling and successful adaptation to the arterial environment, yet often proceeds, in the long-term, to neointimal hyperplasia and graft failure. The laboratory has made the original observation that vein graft adaptation is associated with diminished Eph-B4 expression (Kudo et al., ATVB 27:1562, 2007). We are currently investigating the importance of modulating Eph-B4 function in vein graft adaptation, and have recently published that Eph-B4 is active in adult veins, regulates venous remodeling, and that Eph-B4 function depends on receptor phosphorylation and association with caveolin-1 signaling (Muto et al., J Exp Med 208:561, 2011).

The laboratory is R01 funded from the NIH NHLBI, MERIT funded by the VA, as well as from the Yale Department of Surgery Ohse award. As part of Yale's Vascular Biology and Therapeutics program, the lab is located on the 4th floor of the Amistad building. Members of the Dardik laboratory include surgery residents from Yale and other programs as well as postdoctoral fellows and students from Japan, China, Lebanon and France.

Jeffrey Indes, MD FACS, Associate Program Director in Vascular Surgery, is a board-certified Vascular surgeon. Dr. Indes has extensive experience in all aspects of open and endovascular surgery for Aortic Aneurysms, Thoracoabdominal Aortic Aneurysms, Carotid Artery Disease, Peripheral Artery Disease (PAD), AV Access for Hemodialysis, and Thoracic Outlet Syndrome (TOS), mesenteric and renal vascular diseases. He also offers the newest advancements in endovascular varicose vein treatment, using endovenous Radiofrequency technology to remove varicose veins, it’s less painful and the patient experiences full recovery in days rather than weeks. Studies show it to be as effective as more complicated procedures. He is a registered physician in vascular interpretation (RPVI). Dr. Indes is a graduate of The Mount Sinai School of Medicine where he received special honors in research studying angiogenesis. He completed his residency in General Surgery at Temple University Hospital and fellowship in Vascular and Endovascular Surgery at The Albert Einstein College of Medicine, Montefiore Medical Center. His clinical interests include all aspects of Vascular and Endovascular surgery, with an emphasis on Aortic and Carotid diseases.
