Yindalon Aphinyanaphongs, MD, PhD is an MD/ PhD in the Center for Healthcare Innovation and Delivery Science at NYU Langone Medical Center. Academically he is an assistant professor and his lab focuses on novel applications of machine learning to clinical problems and research and infrastructure regarding model deployment and maintenance. He is also the Director of the Clinical Informatics Training program and helps to design curriculum for training of our students to meet the needs of future employers. Operationally, he is the Director of Clinical Predictive Analytics and the Director of the Clinical Translational Data Science. In this role, he leads a Predictive Analytics Unit that builds, evaluates, benchmarks, and deploys predictive algorithms into the clinical enterprise from his lab, the published literature, and industry.


Saul Blecker, MD MHS is an Assistant Professor of Population Health and   Medicine at the NYU School of Medicine. His research focuses on the epidemiology, outcomes and quality of care for heart failure and related chronic diseases such as diabetes. Dr. Blecker applies health services tools and uses advanced analytic methods to examine large datasets that integrate clinical, utilization and cost data.





Sunita Desai, PhD is an assistant professor of Population Health, with secondary appointments in the Department of Economics at NYU Stern and Heath Policy at NYU Wagner. Dr. Desai is a health economist; her research investigates how policies and incentives shape health care provider behavior and organizational structure. She also examines the role of information and price transparency in consumer decision-making in health care.




Simon Jones, PhD, MSc is a Research Professor in the Department of Population  Health, Division of Healthcare Delivery Science. He brings extensive experience in leveraging data analysis and health informatics in the study of health services research to his role at NYU, where he works with our researchers to support the development and implementation of the Division of Healthcare Delivery Science grants and the Center for Healthcare Innovations and Delivery Science NYULMC-based projects.




Devin Mann, MD MS is an Associate Professor in the Division of Healthcare Delivery Science and Senior Director, Informatics Innovation in MCIT.  A general internist, Dr. Mann also has an appointment in the Department of Medicine, Division of General Internal Medicine and Clinical Innovation. Dr. Mann leads a hybrid program of research and operational innovation focused on enhancing health care delivery using novel technologies.  His research combines the disciplines of informatics, behavioral medicine, human-computer interactions, mHealth and primary care in service of a learning health system and the delivery of effective healthcare. 


Narges Razavian, PhD is an Assistant (Research) Professor in the predictive analytics group in the Department of Population Health and the Center for Healthcare Innovation and Delivery Science. Her research focuses on bridging the gap between machine learning and healthcare, in particular, using most advanced computational models to help with clinical research, including, but not limited to, biomarker discovery, early detection, care quality control, patient similarity, and prediction of future outcomes. From the machine learning point of view, she is excited to work with diverse patient information and high dimensional data (electronic health records, images, text, social, genomics), especially in forms of time series.



Donna Shelly, MD, MPH is a Professor of Population Health and Medicine. Her work is focused on reducing tobacco-related morbidity and mortality in the United States and globally. She has built a rigorous program of translational, population-based, and policy research to optimize implementation of tobacco use treatment in health care delivery systems and to develop innovative ways to improve access to and treatment of nicotine addiction among people with comorbid conditions. Her record of funding includes awards form the National Cancer Institute, National Institute of Drug Abuse, Agency for HealthCare Research and Quality, and the Centers for Disease Control and Prevention.




Cassandra Thiel, PhD is an Assistant Professor with a PhD in Civil Engineering with an emphasis on Sustainable Healthcare and Green Buildings, from the University of Pittsburgh. Her research focuses on systematically measuring and analyzing environmental inefficiencies in medical services and built infrastructures in order to optimize these systems. Specifically, she utilizes sustainable engineering tools, such as life cycle assessment (LCA) and industrial ecology, to improve hospitals, healthcare delivery, and medical waste streams.As a 2014-2015 Fulbright-Nehru Academic and Professional Excellence fellow, she formed collaborative partnerships with ophthalmologists at Aravind Eye Hospitals in India, the University of Maryland, the University of Michigan, and the University of Pittsburgh
