Background

Audrey Williams is the director of LLNL's Forensic Science Center, which supports the U.S. government in chemical, biological, radiological, nuclear, and explosive materials (CBRNE) forensic analysis. She also supports the intelligence community; the Departments of Defense, Homeland Security, and Energy; and local and federal law enforcement.

Prior to her appointment as director, Williams was an analytical and forensic chemist with growing leadership roles in biomedical sample analysis, chemical attribution signatures, toxin analysis, and explosives analysis. She is a technical leader for the development and application of novel analytical methods for biomedical exposure signatures, chemical attribution and forensics, and explosives analysis.

Research Interests

Williams's focus areas are the fusion of multidisciplinary capabilities for application to U.S. national security issues; the characterization of biological signatures of chemical warfare agent exposure; identification, characterization, and interpretation of chemical warfare and toxic industrial chemical attribution signatures in different matrices; comprehensive forensic analyses of extraordinary questioned samples; and the trace and ultratrace materials profiling of a diverse array of explosives, drugs, toxins, and chemical compounds.
