Faculty

Daniel Katz is an Instructor of Medicine and an Advanced Heart Failure and Transplant Cardiologist. He completed internal medicine residency at Massachusetts General Hospital, general cardiology training at Beth Israel Deaconess Medical Center, and then joined Stanford in 2021 for his advanced heart failure training. Since medical school, his research has focused on identifying the various pathophysiologic patterns and mechanisms that lead to the heterogeneous syndrome of heart failure. His efforts leverage high dimensional data in many forms including clinical phenotypes, plasma proteomics, metabolomics, and genetics. He is presently engaged in analysis of multi-omic data from the Molecular Transducers of Physical Activity Consortium (MoTrPAC) and the NHLBI Trans-Omics for Precision Medicine (TOPMed) Program. His clinical interests include advanced heart failure, transplant cardiology, and mechanical circulatory support.

Chloe Reuter is a clinical and research genetic counselor with the Stanford Center for Inherited Cardiovascular Disease and Stanford Center for Undiagnosed Diseases. After growing up in Michigan and completing her undergraduate degree in upstate New York, she fled the cold winters for the wonderfully sunny Bay Area. She completed her MS in Human Genetics and Genetic Counseling at Stanford. Working mostly with adults, her clinical interests include arrhythmogenic cardiomyopathies and patients with undiagnosed genetic conditions. She is actively involved in research pertaining to the integration of genomic technologies into clinical care and defining arrhythmogenic cardiomyopathies, with particular interest in the DSP and FLNC genes. She’s also a clinical supervisor and research mentor to genetic counseling students training at Stanford. Outside of work, she loves all things food and travel!

Kirsten Steffner is a cardiac anesthesiologist and critical care physician in the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University, and a postdoctoral research fellow in the Ashley Lab. Her research focuses on applying deep learning strategies to cardiovascular imaging and multimodal physiologic datasets. Kirsten integrates novel motion-based metrics from echocardiography and cardiac MRI with invasive hemodynamics, clinical outcomes, and proteomics, with the goal of improving diagnosis and risk stratification for patients with complex cardiovascular disease. In addition to her research, Kirsten is a dedicated clinician and teacher, providing perioperative care for patients undergoing complex cardiac surgery and mentoring trainees in anesthesiology, critical care, and echocardiography.

Yuta is an Instructor at Stanford University in the Ashley lab. He graduated and received DVM from Tokyo University of Agriculture and Technology in 2013. At veterinary school, he investigated the valvular disease of dogs. After graduation, he focused on the inherited cardiac diseases, and conducted research on CALM gene mutation-related arrhythmias (Calmodulinopathy) using iPS cell model in Kyoto University where he obtained a PhD in 2017. His current research interests are pathophysiological mechanism and gene therapy approach for inherited cardiac diseases. Outside the lab, he enjoys watching baseball games, reading books, playing video games, and California life.
