METRC Coordinating Center


All activities of the Consortium are coordinated through the METRC Coordinating Center (MCC) located at the Johns Hopkins Bloomberg School of Public Health. The Center works closely with the Steering Committee to ensure that protocols are appropriately designed, executed and analyzed. The Coordinating Center is directed by Ellen MacKenzie, PhD, with Renan Castillo, PhD serving as Deputy Director, Daniel Scharfstein, ScD as Principal Biostatistician and Gregory de Lissovoy, PHD, MPH as Principal Economist. A group of Senior Advisors (James Tonascia, PhD and Curtis Meinert, PhD) provide additional expertise specific to the design and conduct of randomized clinical trials and serve as liaison to both the Biostatistics Center at the Bloomberg School of Public Health and the Johns Hopkins Institute for Clinical and Translational Research (ICTR). Together, these individuals provide leadership for the CC and the Consortium overall.

Additional staff directly responsible for the day to day operations of the Coordinating Center include Directors for 3 core functions: (1) Protocol Development, Implementation and Monitoring; (2) Administration and Regulatory Affairs and (3) Informatics and Biostatistics. Resources of the Johns Hopkins Bloomberg School of Public Health Biostatistics Center further support the data management and analysis activities of the Coordinating Center.
