Probabilistic Reporting in American Criminal Cases: A Baseline Study

The reporting of forensic results is a topic of crucial importance and increasing interest. Existing scholarship primarily addresses how forensic results should or could be reported. Our purpose is to understand empirically how forensic results are actually reported in American trials today. Given that many forensic statisticians are advocating for the greater use of probabilistic reporting, this research may allow us to establish a baseline so we can measure progress toward that goal.

Learning Algorithms for Evaluating Forensic Glass Evidence

Glass evidence may arise when a glass object is broken during the commission of a crime. Small fragments can transfer to the perpetrator.

A panel discussion with NIST researchers and the CSAFE team on the likelihood ratio

This CSAFE Center Wide Webinar was presented on March 1, 2018 by a panel of speakers who examine the impact of the likelihood ratio in a legal context, how to communicate the likelihood ratio to lay audiences and more, followed by a time for questions from the audience.

Comparing Cartridge Breechface Marks: 2D versus 3D

We will describe work that we have done on an automated method to compare breechface marks on 2D images of cartridge cases, and how this transfers to 3D topographies.

Explaining Source Conclusions to a Lay Audience

Forensic scientists are often asked to evaluate whether two items have (or might have) a common source. What is the best way for them to explain the strength of their conclusions in reports and testimony?

Statistical and Algorithmic Approaches to Matching Bullets

CSAFE researchers at Iowa State University will discuss the advances they have made towards providing firearms examiners with an objective, quantifiable and standard approach to describe the degree of similarity observed between two bullets.
