    • Chair, Department of Population Health Science and Policy, Edmond A. Guggenheim Professor of Health Policy, Co-Director, InCHOIR

    As Chair of the Department of Population Health Science & Policy and Co-Director of the International Center for Health Outcomes and Innovation Research (InCHOIR) at Mount Sinai, Dr. Gelijns’ research focuses on the analysis of the long-term clinical outcomes and economic impact of clinical interventions, the factors driving the development and diffusion of medical technology, and their policy implications.


    In particular, her recent work has focused on the design, execution and policy implications of clinical trials of novel surgical procedures, biologicals (including stem cell therapies) and implantable devices.  She directed the data coordinating center (DCC) for the landmark REMATCH trial which established for the first time the survival and quality of life benefit of implanted mechanical circulatory support devices for long-term support of patients with advanced heart failure.  She has extended this work through co-directing the DCC and coordinating a host of ongoing trials exploring the human biology of long-term mechanical circulatory support supported by a NIH-funded SCCOR grant.  She is currently the PI of the DCC for the Cardiothoracic Surgical Trials Network (CTSN), which is funded by NHLBI, NINDS and the Canadian Institutes of Health Research.  As part of the CTSN, she has been involved in trials evaluating surgical approaches to ischemic mitral regurgitation, surgical ablation for persistent atrial fibrillation, infections after cardiac surgery, neuroprotection strategies, and mesenchymal precursor stem calls.


    Dr. Gelijns has served as a consultant to various national and international organizations, including the World Health Organization (WHO), the Organization for Economic Cooperation and Development (OECD), Paris, France, the National Academy of Engineering and the Institute of Medicine, and she was a member of the board of the International Society on Technology Assessment in Health Care.  She is an editor for JACC and JTCVS, and has been appointed a fellow in the American Institute of Medical and Biological Engineering.  Dr. Gelijns received her LLM degree from the University of Leyden in the Netherlands and her PhD from the medical faculty at the University of Amsterdam, while writing her dissertation as an international fellow at the Institute of Medicine, National Academy of Sciences, Washington, D.C. 

    • Professor of Biostatistics, Director of the Center for Biostatistics
    Dr. Bagiella is Professor of Biostatistics in the Department of Population Health Science and Policy and the Director of  the Center for Biostatistics at the Icahn School of Medicine at Mount Sinai (ISMMS). The primary focus  of Dr. Bagiella’s research is the design and analysis of clinical trials and epidemiological studies for novel therapeutics.  She has been the PI of the Data Coordinating Center (DCC) for 6 federally funded multi-center clinical trials and has designed and coordinated more than 15 federally funded clinical trials.  She  has developed new methods for the analysis of heart rate and blood pressure variability and the analysis of multiple outcomes as well as for the analysis of case-control data.  As the Director of the Center for Biostatistics and the Director of BERD (Biostatistics and Epidemiology Research Design), within the CTSA at ISMMS, Dr. Bagiella  interest has focused on enhancing translational research through innovative approaches to the design and analysis of clinical trials, training a new generation of translational researchers and continuing to garner federal support for evaluating the important clinical innovations that are emergent from clinical and translational investigators. Dr.Bagiella is a member of 12 DSMBs, serves on several NIH study sections and was a member of the FDA Peripheral and Central Nervous System (PCNS) Drug Advisory Committee.
