CSAFE works to build a statistically sound and scientifically solid foundation for the analysis and interpretation of forensic evidence. Fair administration of justice requires scientifically valid methods to analyze evidence, relevant databases to support the analyses and appropriate interpretations of the results. In the past — and the present — faulty evidence and invalid inferences derived from the evidence threaten justice. Through research focused on probability and statistics for pattern and digital evidence, cross-cutting issues in the field, and training and education, CSAFE strives to develop stronger scientific foundations, more-objective methods of evidence analysis, and a greater understanding of how to interpret and communicate findings.

Founded in 2015 and partially funded by a cooperative agreement between NIST and Iowa State University, CSAFE is part of a national effort to infuse statistical thinking and rigorous, science-based standards into forensic practice. More than 80 researchers across scientific disciplines collaborate toward CSAFE goals.


Alicia L. Carriquiry

CSAFE Director / Distinguished Professor of Statistics, Iowa State University

As the director and lead investigator at CSAFE, Dr. Carriquiry provides her scientific oversight and research expertise to the organization. She is a distinguished professor of liberal arts and sciences and a professor of statistics at Iowa State University. She serves on the OSAC subcommittee on materials and trace evidence and was recently named to the National Academy of Medicine and elected as a fellow to AAAS.

Research reports:

Karen Kafadar

CSAFE Co-Director / Commonwealth Professor and Chair of Statistics, University of Virginia

Karen Kafadar is a Commonwealth Professor and the Chair of Statistics at the University of Virginia, Charlottesville. Her research focuses on robust methods; exploratory data analysis; characterization of uncertainty in the physical, chemical, biological and engineering sciences; and methodology for the analysis of screening trials, which includes awards from the Centers for Disease Control and Prevention, American Statistical Association (ASA), and American Society for Quality. She was a former member of OSAC’s Forensic Science Standards Board (2014-2018) and former chair of the ASA’s Committee on Statistics in Forensic Science. She is presently Editor-in-Chief of The Annals of Applied Statistics and was 2019 President of the American Statistical Association.

Hal S. Stern

CSAFE Co-Director / Interim Provost and Executive Vice Chancellor and Chancellor’s Professor of Statistics, University of California, Irvine

Hal Stern is the Interim Provost and Executive Vice Chancellor and Chancellor’s Professor of Statistics at the University of California, Irvine. Dr. Stern is known for his research in Bayesian statistical methodology and model assessment techniques, and his current areas of research include applications of statistical methods in psychiatry and human behavior and forensic science.  He has significant experience in addressing the role of statistical methods in the practice of forensic science. He has been a member of the Physica/Pattern Interpretation Scientific Advisory Committee (PSAC) of the Organization of Scientific Advisory Committees for Forensic Science from the formation of that committee in 2014.  The PSAC is an interdisciplinary group that reviews proposed standards and best practices in the pattern disciplines.

Research reports:
Latent Print Examination and Human Factors: Improving the Practice (2012)

Brandon Garrett

CSAFE Co-Director / L. Neil Williams, Jr. Professor of Law, Duke University

Brandon L. Garrett serves as the L. Neil Williams, Jr. Professor of Law at Duke University, where he is the founder and Director of the Center for Science and Justice. Garrett’s research and teaching focuses on forensic science, eyewitness identification, corporate crime, constitutional rights and habeas corpus, and criminal justice policy. Garrett’s work has been widely cited by courts, including the U.S. Supreme Court. Garrett also frequently speaks about criminal justice matters before legislative and policymaking bodies, groups of practicing lawyers, law enforcement, and to local and national media. He is involved with a number of law reform initiatives, including the American Law Institute’s project on policin

Robin Mejia

CSAFE Co-Director / Director, Program in Statistics and Human Rights, Carnegie Mellon Center for Human Rights Science

Robin Mejia’s work with CSAFE focuses on improving proficiency testing and forensic statistics education. She also directs the program in Statistics and Human Rights at the CMU Center for Human Rights Science, where she studies incarceration, and she teaches survey design and analysis. Mejia is co-chair of the Committee on Scientific Freedom and Human Rights for the American Statistical Association. Prior to earning a PhD in biostatistics at UC Berkeley, she worked as a science journalist, including covering challenges to the forensic use of comparative analysis of bullet lead for the LA Times in in 2003. Her 2005 CNN documentary “Reasonable Doubt,” which covered additional challenges in forensic science, won the Livingston Award.

Keith Morris

CSAFE Co-Director / Ming Hsieh Distinguished Teaching Professor of Forensic & Investigative Science, West Virginia University

Dr. Keith Morris serves as a co-director of CSAFE, overseeing center activities at West Virginia University. His research interests are focused on the interpretation of physical evidence and how multiple types of evidence are interrelated. Dr. Morris’ interest in evidence types centers on firearms evidence, ballistics, and latent fingerprint identification and utilizing systems such as AFIS, IBIS, and confocal microscopy that relate directly to his research focus. He also serves as the Ming Hsieh Distinguished Teaching Professor of Forensic & Investigative Science at WVU.
