Samrat (Sam) Chatterjee was selected to lead a subgroup on analytic development as part of the Risk Architecture Lab Performers Council of the Department of Homeland Security (DHS), Cybersecurity and Infrastructure Security Agency (CISA), National Risk Management Center (NRMC). This subgroup is comprised of representatives from multiple national laboratories, including Pacific Northwest National Laboratory (PNNL), Sandia National Laboratories, Idaho National Laboratory, Argonne National Laboratory, and Lawrence Livermore National Laboratory.

The Risk Architecture Lab Performers Council collectively informs CISA’s NRMC of new directions and research areas to pursue for infrastructure risk and resilience modeling and analysis efforts. Recently, several subgroups were formed to focus on specific topics. Chatterjee’s experience in cyber and physical infrastructure network resilience modeling and simulation, risk and decision optimization under uncertainty, and graph and data analytics positions him as an ideal leader for the analytic development subgroup. As such, Chatterjee will drive the development of guidance material to help shape direction on risk architecture analytic development.

“I am thrilled to be working with DHS-CISA-NRMC and partners from the national laboratories to advance risk architecture analytic development,” said Chatterjee. “Not only will we have the opportunity to help shape direction in this area, we will also get the chance to strengthen our collaborations amongst the group.”

At PNNL, Chatterjee is a senior data/operations research scientist and team leader of the Data Sciences and Machine Intelligence group within the Advanced Computing, Mathematics, and Data Division. He serves as principal investigator, project manager, and key technical staff member on national security and computational science research efforts in support of multiple sponsors, including DHS, Department of Energy, and Department of Defense. Chatterjee also serves as chief scientist for PNNL’s Mathematics for Artificial Reasoning in Science (MARS) Initiative, and holds an affiliate faculty appointment with Northeastern University in Boston, Massachusetts.

Prior to PNNL, Chatterjee conducted postdoctoral research on infrastructure risk and decision analysis, and operations research at the DHS Center for Risk and Economic Analysis of Threats and Emergencies—or CREATE—a Homeland Security Center of Excellence at University of Southern California. He has authored two books, four book chapters, and over 75 peer-reviewed journal articles, conference papers, and technical reports. He also has received multiple best paper and poster awards. He is a past chair of the Security and Defense and the Engineering and Infrastructure specialty groups within Society for Risk Analysis and is a senior member of the Institute of Electrical and Electronics Engineers. He holds a doctorate in civil systems engineering from Vanderbilt University.
