    Current Research and Scholarly InterestsDr. Michael S. Kapiloff is a faculty member in the Departments of Ophthalmology and Medicine (Cardiovascular Medicine) and a member of the Stanford Cardiovascular Institute. Although Dr. Kapiloff was at one time a Board-Certified General Pediatrician, he is currently involved in full-time basic science and translational research. His laboratory studies the basic molecular mechanisms underlying the response of the retinal ganglion cell and cardiac myocyte to disease. The longstanding interest of his laboratory is the role in intracellular signal transduction of multimolecular complexes organized by scaffold proteins. Recently, his lab has also been involved in the translation of these concepts into new therapies, including the development of new AAV gene therapy biologics for the prevention and treatment of heart failure and for neuroprotection in the eye.

  • Karthikeshwar Kasirajan (Kasi)

    Karthikeshwar Kasirajan (Kasi)

    Clinical Professor, Surgery - Vascular Surgery

    BioDr. Kasirajan is a board-certified, fellowship-trained vascular surgeon. Also known as Dr. Kasi, he is a clinical professor of vascular surgery at Stanford University School of Medicine.

    Dr. Kasirajan preserves limbs, facilitates access to dialysis, and helps his patients manage conditions such as aneurysms, varicose veins, thoracic outlet syndrome, and deep vein thrombosis. Many of his limb preservation patients smoke, have diabetes, or are experiencing renal failure. Dr. Kasirajan’s experience also centers around the treatment of aneurysms and prevention of strokes.

    In all cases, his goal is to provide either noninvasive or minimally invasive management whenever possible. He performs open surgery only when it is the best option. Dr. Kasirajan treats many patients with stents and stent grafts, which can shorten hospital stays and recovery times.

    Dr. Kasirajan (Kasi) receives referrals of patients from primary care physicians, nephrologists, podiatrists, cardiologists, woundcare specialists, diabetologists, neurologists, and other specialists. He welcomes referrals as early as possible, ideally before patients become symptomatic. A strong proponent of doing early screening for peripheral artery disease, Dr. Kasirajan advocates for the use of the ankle-brachial index (ABI) in routine physical examinations. When providers detect an imbalance between leg and arm blood pressure, Dr. Kasirajan can help create customized strategies to address the cause before the problem worsens.

    In addition to offering excellent vascular care to the community, Dr. Kasirajan joined Stanford to continue pursuing his research interests. He has conducted research into advances in minimally invasive procedures for stroke prevention and for aneurysm management. His research has also focused on how to improve surgery outcomes to help patients suffering from peripheral vascular disease. Dr. Kasirajan has been the investigator in over 40 multicenter studies involving new stent graphs, thrombectomy catheters, and other advances in endovascular technology.

    Dr. Kasirajan has made more than 100 presentations worldwide on minimally invasive vascular surgery techniques and preventive care in the vascular patient. He has spoken at multiple conferences including the Society for Vascular Surgery, Peripheral Vascular Society, and the South Asian American Vascular Society. He has earned numerous honors for his academic achievements, including the prestigious Alpha Omega Alpha award for medical student and resident education.

    As the author of more than 120 journal articles, Dr. Kasirajan’s work has appeared in the Journal of Vascular Surgery, Endovascular Today, Pharmacogenomics Journal, Catheter Cardiovascular Intervention, and many other publications. He also has authored 20 book chapters in textbooks including Medical Management of the Surgical Patient 5th Edition, Advances in Phlebology and Venus Surgery Volume 1, Current Therapy in Vascular Surgery, Mastery of Surgery, and many more.

    Dr. Kasirajan has served on the editorial boards of the Journal of Endovascular Therapy, Annals of Vascular Surgery, International Journal of Angiology, and other publications.

  • Masataka Kawana

    Masataka Kawana

    Assistant Professor of Medicine (Cardiovascular Medicine)

    BioDr. Kawana joined the Advanced Heart Failure and Transplant Cardiology group in 2018. He completed his internal medicine, cardiovascular medicine, and heart failure training at Stanford. He also completed a postdoctoral research fellowship under Dr. James Spudich in the Department of Biochemistry. He is the Medical Director of Ambulatory Heart Failure and Cardiomyopathy Service in the Advanced Heart Failure program. He manages advanced heart failure patients in the clinic, CCU/heart failure service, and post-heart transplant/MCS service. His research interests are in the fundamental mechanism of inherited cardiomyopathies, and he studies the effect of gene mutation on the cardiac sarcomere function using cutting-edge biochemical and biophysical approaches, which would lead to the development of novel pharmacotherapy that directly modulates cardiac muscle protein. He is involved in multiple clinical trials for pharmacotherapy and novel device studies in heart failure and inherited cardiomyopathy.
