Before founding Charles River, he was a Senior Scientist at BBN Technologies, a Research Engineer at C.S. Draper Labs, and a USAF attaché for the Space Shuttle program at NASA Johnson Space Center. Greg was recently a member of the National Research Council (NRC) Committee on Human Factors, having served for more than ten years, and is currently co-chairing the NRC study “Organizational Models: From Individuals to Societies.” He is a Research Affiliate of the MIT Man-Vehicle Laboratory and the Humans and Automation Laboratory. Greg is also a member of the USAF Scientific Advisory Board, serving as past Chair of the Human System Wing Advisory Group for Brooks City Base, as peer reviewer for AFRL, and current member of a Cyberoperations Task Force. He is currently on the board of the Embry-Riddle Research Advisory Board and the Small Business Technology Coalition. Greg obtained his PhD in Aeronautics and Astronautics from MIT in 1977.

Ms. Karen A. Harper

Senior Vice President of Government Services and Principal Scientist

Karen leads Charles River's Government Services business area, directing the research and development activities of our three technical divisions: Cognitive Systems, Decision Management Systems, and Computer Vision Systems. In her role as Principal Scientist, Karen leads projects focused on the simulation of human behavior, at both the individual and organizational levels, and the development of advanced human/computer interfaces (HCIs) for complex command and control systems. She is responsible for the continuing development and application of Charles River's agent-based model of human behavior, now known as AgentWorks. Karen received the B.Eng. degree in Mechanical Engineering from Memorial University of Newfoundland, Canada, in 1995, and the MS degree from the Department of Aerospace and Mechanical Engineering at Boston University in 1997. Her graduate research focused on robotics and control, specifically biologically-inspired robot locomotion.

Mr. Magnús S. H. Snorrason

Vice President of Sensor Processing and Networking and Principal Scientist

Magnús leads projects in both the Government and Commercial Services business areas. His projects are focused on sensor processing, i.e., extracting information content from the real-time data streams generated by a variety of different sensors. The application domains include security & surveillance, navigation, and automatic target recognition, and the work involves computer vision, signal processing, image/video enhancement, object detection/tracking/recognition, 3D reconstruction, and modeling human perception. He manages the development of our VisionKit™ and Verideo™ software products. Magnús has been Principal Investigator on numerous projects sponsored by the DoD and NASA, such as an obstacle detection and path planning project funded by NASA's 2004 Mars rover mission. Magnús completed all coursework and qualifiers in the PhD program in Cognitive and Neural Systems at Boston University. Magnús received his BA degree in Electrical, Computers, and Systems Engineering at Harvard University in 1988.

Dr. Jonathan D. Pfautz

Vice President of Cognitive Systems and Principal Scientist

Jonathan leads research and development projects focused on the application of Cognitive Science and Engineering to complex computational systems. This work spans research in modeling of human perceptual, cognitive, organizational, and social processes; design of multimodal human-computer interfaces; development of intelligent decision-support tools; and application of user-centered design practices in the implementation and distribution of software systems. This work has led to numerous peer-reviewed publications as well as to successful deployment of both commercial and Government software products. Jonathan holds a B.S. and M.Eng. in Computer Science and Electrical Engineering and a B.S. in Brain and Cognitive Science from MIT. He maintains his relationship with MIT as a Research Affiliate with MIT’s Research Lab of Electronics. He received his PhD in Computer Science from Cambridge University, where he focused on improving human perception of depth in computer-generated imagery.

Dr. Scott Neal Reilly

Vice President of Decision Management and Principal Scientist

Scott leads Charles River's Decision Management division, which applies a wide range of Artificial Intelligence and Modeling & Simulation technologies to help people make better decisions. His personal research interests are primarily in building intelligent agents in dynamic, real-time environments. This has led him to work in areas such as real-time agent architectures, emotion modeling, affective decision making, social-behavior modeling, intelligent behavior execution, embedded conversational systems, plan recognition, believable animation, hybrid agent architectures, speech morphing, and interactive scene and narrative management. He is also interested in developing tools to make it possible to build and understand complex, agent-based simulation systems. Scott earned a B.S. in Computer Science from Duke University. He earned his M.S. and Ph.D in Computer Science from Carnegie Mellon University where his research focused on modeling artificially intelligent social and emotional agents.

Dr. Subrata K. Das

Chief Scientist of Government Services

Subrata leads research projects in the areas of high-level and distributed information fusion, decision-making under uncertainty, intelligent agents, planning and scheduling, and machine learning. His technical expertise includes mathematical logics, probabilistic reasoning including Bayesian belief networks, symbolic argumentation, particle filtering, and a broad range of computational artificial intelligence techniques. Subrata held research positions at Imperial College and Queen Mary and Westfield College (University of London). He received his PhD in Computer Science from Heriot-Watt University in Scotland and M.Tech. from Indian Statistical Institute. He is the author of the book, "Deductive Databases and Logic Programming" (Addison-Wesley), "Foundations of Decision Making Agents: Logic, Modality, and Probability" (to be published by World Scientific/Imperial College Press), and co-author of "Safe and Sound: Artificial Intelligence in Hazardous Applications" (MIT Press). Subrata is on the editorial board of the journal Information Fusion (Elsevier Science). Subrata has been a technical committee member and a tutorial lecturer at the International Conferences on Information Fusion and is currently editing a special issue on agent-based information fusion.

Mr. Roger N. Schane

Vice President of Business Development

Roger leads Charles River’s government business development activities.
