The Chemical and Biological Signature Science Group is an interdisciplinary group of approximately 50 biologists, chemists, and engineers that solve research and development challenges related to chemical and biological detection and forensics. Much of the work involves trace detection in complex samples including environmental, food, or biological samples, and is directed toward national security missions to prevent and counter acts of terrorism and the proliferation of weapons of mass destruction. Key challenges include: identifying the appropriate signatures, sample collection/preservation and preparation, development of detection and analysis technologies, and development of approaches and analytical methods for high confidence measurements. These challenges are addressed by two teams within the group:
