As the daughter of Navy officers, Dr. Cowan has moved around quite a bit, however has never lived in the Pacific Northwest and is excited to explore the area with her two Labradors. In her free, time she also enjoys scuba diving and watching ice hockey.
Dr. Jeffrey Keenan, Assistant Professor, Division of Cardiothoracic Surgery
Dr. Keenan’s primary area of interest is adult cardiac surgery with a focus in heart failure, including cardiac transplantation and mechanical circulatory support. He grew up in Baltimore, MD and received his bachelor’s degree from the University of North Carolina at Chapel Hill. He then spent a year working in an immunology laboratory at the National Institutes of Health in Bethesda, MD, before matriculating to the University of Maryland for medical school, where he was elected to the AOA honor society. He spent 9 years at Duke University Medical Center training in general and subsequently cardiothoracic surgery. During this time, he also completed a two–year research fellowship supported by a post–doctoral National Research Service Award from the NIH investigating aspects of mitochondrial quality control in the myocardium and conducting health services research in the department of surgery. Dr. Keenan is excited to join the faculty at UW and hopes to contribute to its rich tradition in cardiothoracic surgery. After spending his entire life on the east coast, he also looks forward to exploring Seattle and the pacific northwest with his wife Allison and their four kids, including 2–year–old triplets.
Dr. Maziar Khorsandi, Assistant Professor, Division of Cardiothoracic Surgery
Dr. Khorsandi was born and raised in Tehran. He was inspired by his father, an orthopaedic surgeon, and pursued a path in medicine. He completed his schooling in London, England and was admitted to the University of Dundee School of Medicine, Scotland, UK. While in medical school, he dedicated 1 year to full–time research and obtained intercalated Bachelor of Medical Sciences (BMSc) with honours. Upon graduating from Medical school (MBChB, 2010), he completed General Surgery residency in Manchester, England. During his general surgery training he developed an interest in cardiothoracic surgery and completed a part–time research master’s (MSc) in examining the outcomes of thoracic trauma in England following centralisation of major trauma care in that country. After completion of his general surgical training, he matched into the Scottish training program in cardiothoracic surgery through UK national selection (NTN) and completed a 6–year integrated training. During his specialty training he completed the USMLE exams and undertook a 12–month “Out–of–Program” subspecialty fellowship in cardiopulmonary transplantation and mechanical circulatory support at Duke University Medical Center, NC, USA. He completed his board certification examination in cardiothoracic surgery and was awarded Fellowship of the Royal College of Surgeons of Edinburgh in Cardiothoracic Surgery (FRCS C/Th), 2019. He then completed his specialty training in 2020. He has clinical and academic interest in general adult cardiac surgery and more specifically advanced heart failure therapies. He is the managing editor of the “Oxford Specialist Handbook in cardiopulmonary transplantation and mechanical circulatory support”, an international collaboration project, which is currently in the editing process. Dr. Khorsandi is excited to return to the USA and work at UW Medicine for the new stage in his career. He is passionate about outdoor activities such as skiing and hiking.
David Mauchley, MD, Associate Professor, Division of Cardiothoracic Surgery
Dr. Mauchley’s primary areas of interest are pediatric cardiac surgery, neonatal hear t surgery, mechanical circulatory support in children and cardiac transplantation and his primary site of practice is Seattle Children's Hospital. He grew up in Moscow, ID, and received his bachelor's degree from the University of Idaho, then went to medical school at the University of Washington. Dr. Mauchley completed general surgery and adult cardiothoracic surgery residencies at the University of Colorado—Denver and spent one year completing his training at Children's Hospital—Colorado. During his general surgery training, he spent two years in a basic science fellowship studying the inflammatory mediators of esophageal reflux. After completing his training, he spent 3.5 years as an assistant professor of surgery at the University of Alabama at Birmingham where the focus of his practice was pediatric and adult congenital cardiac surgery. Dr. Mauchley is excited to return to the northwest to continue his career closer to home. Outside of work he enjoys spending time with his family, biking, hiking, and snowboarding.
Sara Rasmussen, MD, Associate Professor, Division of Transplant Surgery
Dr. Rasmussen is trained in Pediatric and Abdominal Transplant surgery. She earned her bachelor ’s degree from the University of Virginia and matriculated medical school at West Virginia University, where she earned her MD and PhD. Her doctoral research investigated mechanisms of retroviral reverse transcription and assembly, and she was awarded a National Cancer Institute Pre–Doctoral Training Award.
Following medical school, Dr. Rasmussen obtained General Surgery training at Virginia Commonwealth University in Richmond and she completed her Pediatric Surgery fellowship at Johns Hopkins. In 2011, she joined the faculty at the University of Virginia (UVA), where she also completed a fellowship in Abdominal Transplant Surgery.
During her tenure at UVA, Dr. Rasmussen was the Surgical Director of the Pediatric Abdominal Transplant Program, and she worked closely with colleagues in Liver Transplant at the University of Pittsburgh Medical Center Children's Hospital of Pittsburgh to re–open the pediatric liver transplant program at UVA , where in less than 4 years they successfully transplanted 23 children.
Dr. Rasmussen had a successful research program in methods of Undergraduate Medical Education at UVA before she pivoted back to translational research in the effects of endogenous retroviruses on the pathogenesis of human cancer, using bioinformatics and bench work in her investigations. She was also a clinical and academic mentor to many undergraduate and medical students, and surgery residents.
Dr. Rasmussen is excited to join the Division of Transplant Surgery as the Surgical Director of Liver Transplant at Seattle Children’s Hospital. She is joined by her husband, Julian, and her three children Catriona, Gareth, and Rhys Siobhan.
Mark Sturdevant, MD, Associate Professor, Division of Transplant Surgery
Dr. Sturdevant ’s interest lies in adult and pediatric liver transplantation with a particular focus in living donor and split liver transplantation in addition to complex hepatobiliary surgery, including the use of minimally–invasive techniques. He has experience in the resection of abdominal tumors involving the hepatic hilum and inferior vena cava, liver resections requiring vascular reconstructions, and bile duct resections and reconstructions. In addition, Dr. Sturdevant performs both kidney and pancreas transplants, live donor nephrectomy, and general surgical procedures particular to those with end–stage liver (including portal decompression procedures) and kidney disease.
His primary sites of practice will be University of Washington Medical Center – Montlake Campus, Seattle Children’s Hospital, and the VA Puget Sound Health Care System. Born and raised in Sioux City, Iowa, Dr. Sturdevant stayed close to home to complete his bachelor ’s degree in biology, his medical degree, and a one–year student fellowship in surgical pathology at the University of Iowa. His general surgery training was completed at the Carolinas Medical Center in Charlotte and his transplant training started with an abdominal transplant fellowship at the University of Minnesota. He has since held faculty positions in the Divisions of Transplant at The Mount Sinai Hospital in New York City, the University of Pittsburgh, and most recently he spent four years as a Consultant Surgeon in adult and pediatric liver transplantation and hepato–pancreato–biliary surgery at the King Faisal Specialist Hospital & Research Center in Riyadh, Saudi Arabia. He is excited to add in any way to the breadth of the transplant and hepatobiliary care currently offered at UW.
After moving to Seattle from the Arabian Peninsula, he is very much looking forward to taking in the colors and coolness of the Pacific Northwest.
