CSAFE’s Latest Resources
Change cannot happen without community. CSAFE is passionate about achieving its mission to apply a statistically sound and scientifically solid foundation to the interpretation of forensic evidence. To that end, we invite fellow scientists and researchers, along with those in the forensic and legal communities, to use and share these resources as we work together to elevate forensic science and technology.

A Pioneer in Forensic Science Reform: The Work of Paul Giannelli
Type: Publication Research Area(s): Implementation and Practice
Published: 2018 | By: Brandon Garrett
Few can say, "I told you so," to our entire criminal justice system. Being right about what is wrong with the use of evidence in criminal cases is not a bad thing, but being able to influence the growing response…
Probabilistic Reporting in Criminal Cases in the United States: A Baseline Study
Type: Publication Research Area(s): Implementation and Practice
Published: 2020 | By: Simon Cole
Forensic evidence reporting shows a high degree of adherence to prevailing disciplinary standards. Probabilistic reporting of forensic results remains rare. Probabilistic reports were mostly subjective verbal assignments of posterior probabilities.
Statistical methods for digital image forensics: Algorithm mismatch for blind spatial steganalysis and score-based likelihood ratios for camera device identification
Type: Publication Research Area(s): Digital
Published: 2020 | By: Stephanie Reinders
Forensic science currently faces a variety of challenges. Statistically suitable reference databases need to be developed and maintained. Subjective methods that can introduce bias need to be replaced by objective methods. Highly technical forensic methods need to be clearly and…
Open Forensic Science in R
Type: Publication Research Area(s): Footwear
Published: 2019 | By: Samantha Tyner
This book is for anyone looking to do forensic science analysis in a data-driven and open way. Whether you are a student, teacher, or scientist, this book is for you. We take the latest research, primarily from the Center for Statistics and…
Statistical Methods for the Forensic Analysis of User-Event Data
Type: Publication Research Area(s): Digital
Published: 2020 | By: Chris Galbraith
A common question in forensic analysis is whether two observed data sets originate from the same source or from different sources. Statistical approaches to addressing this question have been widely adopted within the forensics community, particularly for DNA evidence, providing…
Hunting wild stego images, a domain adaptation problem in digital image forensics
Type: Publication Research Area(s): Digital
Published: 2020 | By: Li Lin
Digital image forensics is a field encompassing camera identication, forgery detection and steganalysis. Statistical modeling and machine learning have been successfully applied in the academic community of this maturing field. Still, large gaps exist between academic results and applications used…
How Can a Forensic Result Be a ‘Decision’? A Critical Analysis of Ongoing Reforms of Forensic Reporting Formats for Federal Examiners
Type: Publication Research Area(s): Implementation and Practice
Published: 2020 | By: Simon A. Cole
The decade since the publication of the 2009 National Research Council report on forensic science has seen the increasing use of a new word to describe forensic results. What were once called “facts,” “determinations,” “conclusions,” or “opinions,” are increasingly described…
Psychometric Analysis of Forensic Examiner Behavior
Type: Publication Research Area(s): Forensic Statistics,Implementation and Practice
Published: 2019 | By: Amanda Luby
Forensic science often involves the comparison of crime-scene evidence to a known-source sample to determine if the evidence and the reference sample came from the same source. Even as forensic analysis tools become increasingly objective and automated, final source identifications…
Quantifying the similarity of 2D images using edge pixels: An application to the forensic comparison of footwear impressions
Type: Publication Research Area(s): Footwear
Published: 2020 | By: Soyoung Park
We propose a novel method to quantify the similarity between an impression (Q) from an unknown source and a test impression (K) from a known source. Using the property of geometrical congruence in the impressions, the degree of correspondence is…
