CSAFE 2021 Field Update

The 2021 Field Update was held June 14, 2021, and served as the closing to the first year of CSAFE 2.0.

CSAFE brought together researchers, forensic science partners and interested community members to highlight the organization’s achievements, identify areas for collaboration, and discuss goals for the future. It was an opportunity to connect with innovative experts in statistical foundations, pattern and digital evidence, and training and education to learn from each other and discuss potential collaborations.

The available insights, presentation slides, and recordings of the research updates are available below. All videos, along with other CSAFE webinars, can be viewed on the CSAFE YouTube channel.
