DNA Detectives: Using DNA in the Environment to Study Fish and Wildlife

Presented by Dr. Andrea Schreier, Director of the UC Davis Genomic Variation Laboratory

Date: January 22, 2026

Time: Mixer 5 – 6 p.m., Lecture 6 – 7 p.m.

Location: TBD

Every organism leaves traces of its genetic identity behind—tiny fragments of DNA shed into water, soil, and air. Scientists can now collect and analyze these genetic clues, known as environmental DNA (or eDNA), to detect species without ever seeing or capturing them. In this talk, Dr. Andrea Schreier of UC Davis will reveal how her team uses eDNA to study fish and wildlife across California and beyond. From tracking endangered species and invasive invaders in the Bay-Delta to monitoring fish communities in restored wetlands, eDNA is transforming how we understand and manage aquatic ecosystems. Dr. Schreier will discuss how this technology works, what it can—and can’t—tell us, and how innovations like CRISPR-based detection tools are opening new frontiers in conservation genomics. Join us to explore how modern molecular techniques are helping scientists become true DNA detectives, uncovering hidden biodiversity in our changing world.
