Manchula Navaratnam
Clinical Professor, Anesthesiology, Perioperative and Pain Medicine
BioDr. Manchula Navaratnam is a Clinical Professor of Anesthesiology, Perioperative, and Pain Medicine at Stanford University, specializing in Pediatric Cardiac Anesthesia. With over 16 years of expertise in the perioperative care of pediatric patients with complex cardiac conditions, Dr. Navaratnam serves as the anesthesiology lead for pediatric cardiac transplantation, ventricular assist devices, single ventricle physiology and perioperative hemostasis management.
Dr. Navaratnam’s research includes pivotal work on left ventricular outflow tract velocity time integral (LVOT VTI) as a measure of ventricular function, now widely utilized at Stanford Children’s Hospital. Dr Navaratnam has led multidisciplinary clinical studies to improve care for single ventricle physiology patients, developed standardized pathways for perioperative hemostasis management, and recently contributed to an FDA-funded multicenter trial investigating pulse oximetry accuracy in congenital heart disease patients with darker skin tones.
As a dedicated mentor and educator, Dr. Navaratnam founded and directs the Pediatric Cardiac Anesthesia Learning (PCAL) workshop for fellows nationwide and leads Stanford’s undergraduate course, “Mending a Broken Heart.” Dr Navaratnam's mentorship has supported numerous trainees and collaborators, resulting in award-winning presentations and impactful research contributions. Dr. Navaratnam is an associate editor for Pediatric Anesthesia, an active peer reviewer for leading journals, a coach and board member for the Congenital Cardiac Anesthesia Society, and an active contributor to national committees and task forces advancing faculty development and the field of pediatric cardiac anesthesia.
Dr. Navaratnam's mission is providing exceptional and compassionate patient care while training the next generation of leaders in the field. -

Mark Nicolls
Stanford University Professor of Pulmonary and Critical Care Medicine
Current Research and Scholarly InterestsOur lab focuses primarily on the contribution of the immune response to lung disease. We are specifically examining the contribution of inflammation to the development of vascular injury in transplantation, pulmonary hypertension and lymphedema.

Koen Nieman
Professor of Medicine (Cardiovascular Medicine) and of Radiology (CV Imaging)
Current Research and Scholarly InterestsDr Nieman investigates advanced cardiac imaging techniques. Current projects focus on the development of functional CT application for hemodynamic interpretation of coronary artery disease, and the clinical validation of cardiac CT in the management of patients with ischemic heart disease.

Joyce Njoroge, MD
Clinical Assistant Professor, Medicine - Cardiovascular Medicine
BioDr. Njoroge is a board-certified physician and fellowship-trained cardiologist with the Advanced Heart Failure Program at Stanford Health Care. She is also a clinical assistant professor of medicine in the Division of Cardiovascular Medicine.
Dr. Njoroge has extensive clinical experience diagnosing and treating cardiovascular complications that develop during pregnancy or postpartum. She currently provides care at the Stanford Health Care Heart and Vascular Clinic with a particular focus on patients with a history of pregnancy-associated heart failure and cardiomyopathy.
Dr. Njoroge’s research efforts involve identifying inherited genetic changes and biological markers that could help improve screening and care for pregnant women in higher risk populations. This includes determining the causes of disproportionately high incidences of heart-related complications and deaths experienced by Black women during and after pregnancy. Dr. Njoroge is also currently recruiting patients for a large-scale, multicenter clinical trial evaluating a drug to treat cardiovascular complications during pregnancy.
Dr. Njoroge has published her work in numerous prestigious peer-reviewed journals, including Circulation Research and the Journal of Cardiac Failure. She also co-authored a chapter on cardiovascular disease in pregnancy in the most recent edition of the book Current Diagnosis and Treatment: Cardiology.
Dr. Njoroge is a member of the Association of Black Cardiologists, the American College of Cardiology, the American Heart Association, and the Heart Failure Society of America.
