Brett Didier is a Senior Research Scientist in the Computational Sciences and Mathematics Division at Pacific Northwest National Laboratory.

Didier joined PNNL in 1982 as a technical specialist in the Statistical Sciences and Analysis group. His professional experience at the Lab ranges from the development and analysis of meteorological models and leading teams in the development of mission command and control systems and document management systems, to his most recent activities in the investigation, development, and deployment of problem-solving and collaborative environments. He has over 15 years of experience at PNNL leading software development teams.

Currently, he is the PNNL principal investigator for the DHS Science and Technology Biodefense Knowledge Center project. The project involves the development of an extensible analytical software environment for integrating suites of domain-specific analysis tools and heterogeneous data sources. This software has attracted interest from several organizations within the intelligence community resulting in five pilot deployments and ongoing discussions for several additional opportunities within the last year.
