    S2Ep1 - Cognitive bias in forensic pathology decisions with Dr. Itiel Dror

    In this episode I spoke with Dr. Itiel Dror, a cognitive neuroscientist known in the forensic realm for his contributions to revealing the unconscious implicit biases in forensic decisions and providing tools to minimize them. He recently published several papers examining - for the first time - cognitive bias in forensic pathology. The Maryland Attorney General has announced an independent audit of in-custody death determinations made by the OCME during the tenure of Dr. David Fowler. Dr. Fowler provided expert testimony for the defense in the trial of Derek Chauvin for death George Floyd. The audit team of forensic pathology experts and behavioral scientists will look to ascertain whether or not the determinations of manner of death were free from implicit biases. "...it's important to distinguish between what I'm talking about with cognitive bias versus the way people usually talk about bias. So the usual term bias refers to intentional discrimination like racism and sexism and antisemitism, where it's intentional bias and discriminatory. I'm talking about the way the brain actually works, which affects all of us...It developed because of the architecture of the brain, but sometimes it can lead us to make mistakes, and this is where we want to minimize the way it goes off track, and the cognitive bias gives us a mistake, and it's unconscious implicit bias, so people are not aware of it." - Itel Dror Links for this episode: Biases in forensic experts.

    Ep. 9 (Season 1 Bonus) Massively Parallel Sequencing - Tools for forensic laboratories learning to handle terabytes of genetic data, how it improves investigations, and a free workshop.

    Massively Parallel Sequencing has revolutionized laboratories' ability to harness more and more information from our genetics. This has led to massive improvements in medical diagnostics, public health (think SARs-CoV-2 variant identification), ancestry determinations, and now forensic science has begun adapting this technology to criminal investigations. In this episode I speak with Professor Megan Foley, Teresa Snyder-Leiby, and Sarah Copeland about the challenges laboratories are facing as they adopt this type of DNA testing and tools that are available not only to labs, but also to law enforcement, prosecutors, and defense - including the Innocence Project. This episode is in partnership with the Association of Forensic DNA Analysts and Administrators (AFDAA). Visit afdaa.org to learn more about this professional organization.

    Ep. 8 Identical Twins, drugs, smoking, and crime. Applied Epigenetics with Dr. Athina Vidaki, Erasmus MC, Netherlands

    Epigenetics: The clothes of your DNA. While the DNA sequence contains the instructions, your epigenome controls which part of the instructions are read and used. But how do we use this in forensic science? Learn more about biomarkers linked to smoking, age predication, differentiating between identical twins, narrowing the suspect pool, generating investigative leads, and more. Athina Vidaki, PhD, with Erasmus Medical Center in Rotterdam Netherlands, is a professor of Applied Epigenomics. Her lab is focused on researching biomarkers and developing technologies to apply epigenetics in forensics.
