Frank is a senior statistician at IBM Watson Health, where he supports clients in federal and state government agencies to reform the healthcare delivery system using evidence and statistical science. In his professional role, he focuses on innovative applications of statistical methods for quality and performance measurement, program evaluation, administrative data development, and machine learning for health outcomes of interest. Frank previously served on HPSS as communications officer and program chair and currently serves as representative to the ASA Council of Sections. He remains active in the Washington Statistical Society on the quantitative literacy committee, which supports regional science fairs to recognize high school students for excellence in the practice of statistical science.



Dr. Xie is the Milan and Maureen Ilich/Merck Frosst Chair Professor of Biostatistics in the Faculty of Health Sciences at Simon Fraser University. His research interests include developing tractable and distribution-free statistical methods for incomplete data and their applications in population, clinical and experimental studies of chronic diseases, such as arthritis diseases and cancer. These statistical methods can be used for more powerful evaluation of treatment, program and policy impact, more effective identification of risk factors for cancer, arthritis and other diseases, to quantify and improve the reliability of empirical results using imperfect data, to improve the usability and accessibility of large medical and administrative databases as well as policy simulations.

Lisa Lix is Professor and Tier I Canada Research Chair in the Department of Community Health Sciences at the University of Manitoba in Winnipeg, Canada. She is also Director of the Data Science Platform in the George and Fay Yee Centre for Healthcare Innovation at the University of Manitoba. Her research interests include health services research methodology, quality of administrative health databases, the analysis of repeated measures and longitudinal data, and robust statistical methods for patient-reported outcomes. Dr. Lix collaborates widely on projects about population health and the association between chronic disease and quality of life. She has served the Statistical Society of Canada since 2005 in various leadership capacities and was President of the Biostatistics Section in 2010.

Mousumi Banerjee is Anant M. Kshirsagar Collegiate Research Professor of Biostatistics at University of Michigan’s School of Public Health. She is also the Director of Biostatistics at the Center for Healthcare Outcomes and Policy, and Member of the Rogel Cancer Center at Michigan. Dr. Banerjee's research focuses on machine learning, correlated data, survival analyses, and competing risks, with applications to health services and outcomes research. She studies fundamental issues related to optimal quality, equitable care delivery, and treatment and outcome disparities in cancer and congenital heart disease. She received her BStat and MStat degrees from the Indian Statistical Institute and her PhD in Statistics from the University of Wisconsin. Dr. Banerjee is a Fellow of the American Statistical Association, and an elected member of the International Statistical Institute.



Ruth Etzioni is Full Member in Biostatistics at the Fred Hutchinson Cancer Research Center and Affiliate Professor in Biostatistics and Health Services at the University of Washington. Her research focuses on modeling and analytics to fill in the evidence gaps that inevitably arise when developing policies for cancer early detection and control. Much of her cancer modeling work is done in association with the Cancer Intervention and Surveillance Modeling Network (CISNET) of the NCI. She is also the curriculum designer and principal instructor for the graduate course “Advanced Research Methods: Large Public Databases, Big Data,” in the School of Public Health at the University of Washington. She spent many years not knowing where she belonged in the American Statistical Association before finding a home in HPSS. As HPSS chair for 2019 she is dedicated to creating community and making sure that others doing relevant work feel a sense of belonging within the section.

Michael Baiocchi, PhD, is an Assistant Professor in the Department of Epidemiology and Population Health at Stanford University. He is an interventional-statistician, creating interventions and the means for analyzing them. He specializes in creating simple, easy to understand statistical methodologies for getting reliable results out of messy data and messy situations. His research is in nonparametric estimation and design-based inference. He was the inaugural Stein Fellow in the department of Statistics at Stanford University. He works on policy and health-outcome research in cardiothoracic surgery.

Marino, Miguel_png.png


Miguel Marino, PhD is an Associate Professor of Biostatistics in the Department of Family Medicine at Oregon Health & Science University. Miguel’s current research interest lies in population-based studies using large administrative observational data sources and electronic health records (EHRs). Specifically, his focus is on development and implementation of novel statistical methodology to address complexities associated with the use of EHRs to study changes in policy, health disparities, validation of EHRs as a reliable source for observation studies, and design/analysis of cluster-based randomized trials. Miguel currently serves as the statistical editor for the Annals of Family Medicine. Follow him on Twitter @MmMiguelmM
