Research & Publications
Dr. Wallach’s research focuses on synthesizing, evaluating, and establishing the best evidence to inform research, regulatory, and public health decisions. His primary area of research, known as meta-research (i.e. the study of research itself), includes the key thematic areas of research methods, reporting/transparency, and reproducibility. Dr. Wallach’s research interests include meta-analytical methodology, evaluating study biases, clinical trial design/conduct, pharmacoepidemiology, and regulatory science.
His work with the Collaboration for Research Integrity and Transparency (CRIT) at Yale focuses on evaluating the tools, standards, and approaches used to assess the safety, efficacy, quality, and performance of FDA-regulated products using epidemiologic and meta-research methods. Dr. Wallach is also a Faculty Affiliate of the Meta-Research Innovation Center at Stanford (METRICS).
Dr. Wallach is currently leading or collaborating on numerous studies, including meta-analyses of environmental exposures and clinical interventions, real world data analyses of medications, and meta-research projects with students.
