CCI Welcomes two new members to biostats group

This summer the CCI welcomed two new members to our biostatistics group, Dr. Olesya Baker and Dr. Guohai (Bruce) Zhou. We are very excited to have Dr. Baker and Dr. Zhou join our team! Please read more on their accomplishments below and contact us at cci@bwh.harvard.edu if you would like Dr. Baker or Dr. Zhou to help with your study.

Dr. Baker received her PhD in economics from Boston University, where her training focused on areas of policy research and quasi-experimental methodologies. For the past six years she served as a Statistician in the Division of Health Policy and Public Health in the Department of Emergency Medicine at Brigham and Women’s Hospital, where her work, frequently in large databases, focused on evaluation of health systems initiatives and health policies to improve quality and outcomes of care. Her research collaborations have focused on evaluating impacts of policy changes on the availability, access to, affordability, and use of health care using quasi-experimental research methods and insurance claims and electronic medical record datasets. Her recent projects evaluate opioid prescribing behavior and prescribing guidelines from the ED using state-wide PDMP data. Her methodological areas of expertise include interrupted time series, difference-in-differences, propensity score matching, instrumental variables and regression discontinuity methods.

Dr. Guohai (Bruce) Zhou received his PhD in Statistics from the University of British Columbia. Prior to joining the CCI, Dr. Zhou worked in the Center for Outcomes Research & Evaluation at the Yale School of Medicine. During his time working at Yale, Dr. Zhou worked on multiple projects that used advanced statistical models to facilitate healthcare quality improvement. Dr. Zhou has collaborated with many clinicians and epidemiologists, which led to more than 20 published journal articles. Dr. Zhou has expertise and interests in all mainstream biostatistical areas such as the design and analysis of clinical trials and observational studies. His methodological areas of expertise also include advanced methods for missing data and longitudinal data, which have been published in statistical journals.

Please join us in welcoming Dr. Baker and Dr. Zhou to the team!
