Thomas Trikalinos (Associate Professor and Director)

Tom works on novel methodologies for comparative effectiveness research, with emphasis on the steps of evidence synthesis (by means of systematic review and meta-analysis), and evidence contextualization (by means of decision and economic analysis). Tom and his colleagues strive to modernize and optimize the processes of evidence-based medicine by porting methodologies from computer science and applied mathematics.

Christopher Schmid (Professor and Co-Director) 

My research focuses on statistical methods for meta-analysis, the quantitative synthesis of information from observational and experimental studies. I am concentrating on developing methods and software for simultaneously comparing many treatments for a medical condition in order to determine which is best. I also develop models to enable doctors to work with patients to choose the best treatment through single patient experiments and models for predicting kidney function using multi-study data.


Ethan Balk (Associate Professor, Research)

Ethan Balk, MD MPH, is Associate Professor (Research) in the Brown University School of Public Health. For about 15 years, his research has focused on systematic review, evidence based medicine, meta-analysis, study quality assessment, and evaluation of literature. He has led numerous comparative effectiveness reviews, evidence reports, technologies, and other systematic reviews for the Agency for Healthcare Research and Quality Evidence-base Practice Center program, for other federal and international agencies, and professional organizations. His reviews have covered a breadth of clinical medicine and nutrition topics and areas including cardiovascular disease, diabetes, kidney disease, surgical interventions, prevention, diagnostic tests, dietary supplements, fatty acid intake, and micronutrients, among others. For about 11 years, he collaborated with the KDOQI and KDIGO kidney disease guideline development organizations, leading evidence review teams conducting systematic reviews and training workgroup members in the development of evidence-based guidelines. For about 6 years he has also assisted the Society of Gynecologic Surgeons Systematic Review Group to develop systematic reviews and clinical practice recommendations.

Issa J. Dahabreh (Assistant Professor)

My work focuses on the synthesis of observational and experimental studies of therapeutic interventions and diagnostic tests. I am also interested in applied work on systematic reviews of treatments, medical tests, and risk factors for disease.

Rowan Iskandar (Assistant Professor, Research) 

My research interests lie at the interface of health decision science and mathematical biology. I am interested in the analysis of cancer epidemiology data using mechanistic models of carcinogenesis to reverse-engineer the biological mechanisms of cancer progression and to identify approaches for more effective cancer control strategies. Currently, I am investigating how different assumptions on the timing of the cancer cells spread and how the metastasis process is modeled may lead to biased estimates of the benefit of mammography and adjuvant treatment among early stage breast cancer patients. For this purpose, I have developed a multiscale model that integrates biological data and the observed epidemiological data. This modeling framework can facilitate the inclusion of recent advances in the field of cancer biology coupled with epidemiological data thereby permitting a more evidence-based and comprehensive evaluation of cancer control strategies.

I received my Ph.D. in health services research, policy, and administration with a focus on health decision science from the University of Minnesota, Twin-Cities.

Joseph Lau (Professor Emeritus)

My research focuses on applying evidence-based methods to clinical/healthcare problems. I have long-standing interest in validating existing systematic review and meta-analysis methodologies and developing new ones to make the processes more efficient and the products more reliable. For the past 2 years, I have been developing a Systematic Review Data Repository (SRDR) that could be used by researchers worldwide. I am also working with others to disseminate the methodologies of evidence-based practice beyond the immediate medical settings to other relevant scientific disciplines.

Evangelia Ntzani (Adjuct Assistant Professor) 

Dr. Ntzani is a pediatrician and an Assistant Professor of Epidemiology in the Department of Hygiene and Epidemiology, University of Ioannina, School of Medicine, Greece. Dr Ntzani is author in 42 peer-reviewed scientific papers in clinical and molecular epidemiology and evidence-based medicine, and is co-investigator of grants on genetic epidemiology of complex diseases and motivating behavior change across diverse areas including physical activity and diet. Her research interests include evidence-based medicine, clinical and molecular epidemiology, assessment of large-scale clinical and molecular information, and research methodology and bias.

 Dale Steele (Associate Professor of Emergency Medicine, Associate Professor of Pediatrics) 

Dr. Dale W. Steele graduated from the University of Vermont in 1986. He works in Providence, RI and specializes in Pediatric Emergency Medicine. Dr. Steele is affiliated with Rhode Island Hospital. His professional and academic interests include: Pediatric emergency medicine, medical education, statistics, clinical decision models, Bayesian methods

Andrew Zullo (Assistant Professor of Health Services, Policy, and Practice) 


Andrew R. Zullo, PharmD, ScM, PhD is a nursing home / long-term care pharmacoepidemiologist and health services researcher. He applies comparative effectiveness and safety methodologies to patient-centered outcomes research topics in diabetes, cardiovascular disease, fractures/osteoporosis, infectious diseases, nephrology, and more. His other interests include 1) the quality and determinants of medication use, 2) personal prescription drug importation, and 3) new models of pharmaceutical care delivery and medication management. During his fellowship, Andrew will focus on using observational data to emulate randomized controlled trials of medications and obtain causal treatment effect estimates for outcomes of greatest importance to older adults.
