CSAFE Forensic Learning Opportunities
Harness tools and training that will help improve your accuracy, objectivity and communication as a forensic scientist or stakeholder.
In a joint collaboration between CSAFE researchers and forensic scientists, we develop and facilitate publicly available programs that amplify existing knowledge or build new competencies in the statistical analysis and interpretation of forensic evidence. These programs include short courses, webinars, workshops, and research updates that touch on a variety of topics relevant to the diverse forensic and applied forensic science communities. CSAFE believes that training and education can enhance technical innovation through alignment of measurement science with emerging and innovative fields of research. Check back regularly for new programs, and please contact us with any interest in educational collaborations or with questions.

A database of handwriting samples for applications in forensic statistics
Type: Publication Research Area(s): Handwriting
Published: 2020 | By: Amy Crawford
Handwriting samples were collected from 90 adults for the purpose of developing statistical approaches to the evaluation of handwriting as forensic evidence. Each participant completed three data collection sessions, each at least three weeks apart. At each session, a survey…
Quantifying the association between discrete event time series with applications to digital forensics
Type: Publication Research Area(s): Digital
Published: 2020 | By: Christopher Galbraith
We consider the problem of quantifying the degree of association between pairs of discrete event time series, with potential applications in forensic and cybersecurity settings. We focus in particular on the case where two associated event series exhibit temporal clustering…
Score-based Likelihood Ratios for Camera Device Identification
Type: Presentation Slides Research Area(s): Digital
Published: 2020 | By: Stephanie Reinders
Many areas of forensics are moving away from the notion of classifying evidence simply as a match or non-match. Instead, some use score-based likelihood ratios (SLR) to quantify the similarity between two pieces of evidence, such as a fingerprint obtained…
Algorithm mismatch in spatial steganalysis
Type: Presentation Slides Research Area(s): Digital
Published: 2019 | By: Stephanie Reinders
The number and availability of stegonographic embedding algorithms continues to grow. Many traditional blind steganalysis frameworks require training examples from every embedding algorithm, but collecting, storing and processing representative examples of each algorithm can quickly become untenable. Our motivation for…

Crime Lab Proficiency Testing and Quality Management
Type: Webinar Research Area(s): Latent Print
In the wake of recent reports documenting the vulnerability of forensic science methodologies to human error (e.g., NAS, 2009; PCAST, 2016), the field has sometimes pointed to proficiency testing as evidence of disciplines’ validity and/or reliability. However, current proficiency procedures…
Automatic Classification of Bloodstain Patterns Caused by Gunshot and Blunt Impact at Various Distances
Type: Publication Research Area(s): Bloodstain
Published: 2020 | By: Yu Liu
The forensics discipline of bloodstain pattern analysis plays an important role in crime scene analysis and reconstruction. One reconstruction question is whether the blood has been spattered via gunshot or blunt impact such as beating or stabbing. This paper proposes…

A Robust Approach to Automatically Locating Grooves in 3D Bullet Land Scans
Type: Publication Research Area(s): Firearms and Toolmarks
Published: 2019 | By: Kiegan Rice
Land engraved areas (LEAs) provide evidence to address the same source–different source problem in forensic firearms examination. Collecting 3D images of bullet LEAs requires capturing portions of the neighboring groove engraved areas (GEAs). Analyzing LEA and GEA data separately is…
DNA Mixture Interpretation: Thoughts and Lessons Learned from a NIST Scientific Foundation Review
