Senior Fellows

Ariya Chau, MD

Pediatric Cardiovascular Intensive Care

Training Dates: 7/07/2023 - 7/06/2024

Ariya completed her pediatric residency at UC Irvine/Children's Hospital of Orange County. During residency, her research was focused on fluid management in diabetic ketoacidosis. She completed her PICU fellowship at Children's Hospital Los Angeles where she studied risk factors for development of post traumatic stress after ICU admission. She has spent the last year here at Stanford as a CVICU hospitalist and has been studying patency of carotid artery reconstruction following ECMO in children with congenital heart disease. She is particularly interested in mechanical support including mechanical ventilation, mechanical circulatory support such as ECMO or VAD, and CRRT. Outside of work, she enjoys spending time with her husband and two children. 

Maneesha Limaye, MD, MPH

Pediatric Cardiovascular Intensive Care

Training Dates: 7/07/2023 - 7/06/2024

Maneesha is originally from Southern California and attended Stanford for her undergraduate studies in Biology and Humanities. She earned her MD and MPH from the University of Miami and completed her residency in Pediatrics at UC Irvine/Children’s Hospital of Orange County (with Ariya!) where she was voted the top resident for clinical excellence. She completed her pediatric critical care medicine fellowship at Stanford and was nominated for inpatient fellow of the year. Her academic interests include ECMO, ECPR, and anticoagulation. Currently, she is actively engaged in research that aims to understand the perspectives and attitudes of healthcare teams providing ECPR. She has presented her findings at national conferences and hopes to expand this project into a multi-site study. Outside of work, she enjoys traveling, hiking, and taking road trips with her dog Sophie. 

Zsofia (Zsofi) Long, MD

Pediatric Cardiac Catheterization

Training Dates: 7/07/2023 - 7/06/2024

Zsofia completed medical school at UT Southwestern. She completed her Pediatrics training here at Stanford. Prior to fellowship, she was a CVICU hospitalist at Johns Hopkins All Children’s Hospital and Stanford for several years. 

During her categorical cardiology fellowship she completed a graduate course in Biodesign. She is excited to start her interventional cardiology training this year. She has three busy children, and in her free time, she enjoys yoga, hiking, book club and cooking. 

Andres Moreno Rojas, MD

Pediatric Non-Invasive Imaging Fellow (MRI/ECHO)

Training Dates: 7/07/2023 - 7/06/2024

Dr. Moreno was born and raised in Colombia, South America, where he completed his medical school and first pediatric residency at the Military University in Bogota. Early in his pediatric training, he discovered a passion for cardiology, so as a pediatric resident, he started training in echocardiography during an abroad rotation at the University of Chile. Dr. Moreno was part of the “Regale una Vida” (Gift a Life) program with the Fundacion Cardio Infantil, where he volunteered to evaluate and treat children with congenital heart disease in remote areas of Colombia. Due to his love for pediatric cardiology and research interest, Dr. Moreno moved to the United States to train as a Pediatric Cardiologist. He completed his second pediatric residency at the University of Connecticut and then his Cardiology fellowship at the University of California San Diego. His main areas of interest are the use of MRI in cardio-oncology and evaluating patients with single ventricle physiology. Dr. Moreno’s additional interests include using artificial intelligence in imaging interpretation and automatization of processes. During his free time, Dr. Moreno enjoys cooking traditional Colombian recipes, biking, and traveling with his family.

Brittany Navarre, MD

Pediatric Electrophysiology

Training Dates: 7/07/2022 - 7/06/2024

Brittany grew up in the small town of Cle Elum, WA. She attended Washington State University where she received her BS in Neuroscience and met her husband, Tim. Between college and medical school she completed a 2-year research fellowship at the National Institute on Drug Abuse in Baltimore, MD. She attended medical school at the University of Washington followed by pediatric residency at Phoenix Children's Hospital. She moved back to the West Coast for her pediatric cardiology fellowship at Stanford and is excited to be staying for a 4th year advanced fellowship in electrophysiology. Hobbies: Trail running, mountain biking, snowboarding, inline skating, bouldering, nature inspired art.

Aaron Phillips, MD

Pediatric Non-Invasive Imaging Fellow (Fetal/ECHO)

Training Dates: 7/07/2023 - 7/06/2024

Aaron joined us from Children’s National Medical Center in Washington DC where he completed his residency and now has completed his categorical fellowship here at LPCH. He is now joining us to complete an advanced imaging fourth year where he is focused on fetal echocardiography. He obtained his Bachelor of Science in biology at Wheaton College, IL and his MD at Loma Linda University. His research throughout fellowship focused on using novel metrics in fetal echocardiography including arch angulation and fetal strain to predict surgical coarctation. He is originally from Bend, Oregon and he enjoys music and playing guitar with his wife and son (who join on the piano). 

Drishti Tolani, MD

Pediatric Heart Failure/Transplantation (PACT)

Training Dates: 7/01/2023 - 6/30/2024

Drishti was born and raised in Mumbai, India where she completed her medical school at Seth GS Medical School and KEM Hospital. She completed her pediatric residency at Children's Hospital of Michigan. She moved to Texas to complete her fellowship in Pediatric Cardiology at UT Southwestern Medical Center/Children's Medical Center Dallas. During her categorical fellowship, she worked on various research projects with a focus on the clinical applicability of a rejection risk score to limit endomyocardial biopsies and non-invasive modalities for diagnosis of coronary vasculopathy. She has presented her research at the International Society for Heart and Lung transplantation conference. Clinically she is particularly passionate about the use of ventricular assist devices in pediatric patients and optimization of oral heart failure regimen in pediatric patients. She loves teaching (and talking) and takes every opportunity she gets to teach residents and medical students. She received teaching awards in both residency and fellowship. In her free time, she is always exploring new restaurants, trying different cuisines and is always searching for the nearest water body to kayak.
