Dr. Alok R. Chaturvedi is a Professor in Purdue University’s Krannert Graduate School of Management and the Department of Computer Sciences (courtesy) and the Founder, Chairman, and the CEO of Simulex Inc., a Modeling and Simulation Company located in Purdue Technology Park. He is the technical lead for US Department of Defense’s Sentient World Simulation project. Dr. Chaturvedi is the founding Director of Purdue Homeland Security Institute and has also served as an Adjunct Research Staff Member at the Institute for Defense Analyses (IDA), Alexandria, Virginia – a leading think tank on national and homeland securities matters.

He received his Ph.D. in Management Information Systems and Computer Science from the University of Wisconsin-Milwaukee. He is an accomplished scholar and thinker and has published extensively in major journals and conference proceedings. Dr. Chaturvedi has been working on multi-agent synthetic environments for over fifteen years. He has led a team of researchers to develop the Synthetic Environment for Analysis and Simulation (SEAS). SEAS is extensively being used by the US Department of Defense for war games, experimentations, planning, analysis, operations, and shaping in multiple theaters. National Training Simulations Association (NTSA) recognized SEAS as the best simulation for analysis in all of Department of Defense for the year 2005. Dr. Chaturvedi is the Principal Investigator (PI) and the Project Director for several major grants from National Science Foundation, Indiana 21st Century Research and Technology Fund, Office of Naval Research, Defense Acquisition University, and several Fortune 500 companies. He has been involved with several Government task forces on important public policy and national security matters. Professor Chaturvedi was named in Federal 100 by Federal Computer Weekly and was awarded the “Sagamore of the Wabash” by the Governor of Indiana, the highest civilian award for his service to the State.

Ms. Chih-Hui Hsieh is a Research Associate at the SEAS Lab. She has extensive research experience with SEAS, epidemiological modeling, agent-based programming, and simulation modeling in the area of MIS, Economics, Business and Homeland Security. Chih-Hui also played a key part in the Measured Response exercises of 2002, 2003, 2004 and 2005, where she configured and developed software interface modules using SEAS architecture.

Tejas joined the SEAS lab in June 2004 as a research associate for programming support. He works as a programming specialist in creating agent-based models and simulations for use in discovery, learning and engagement. He plays a significant role in creating next generation web based collaborative applications for research and training in areas including but not limited to homeland security, preparedness planning and exercise, business economics and supply chain management, human computer interaction, and computer science.

He works as a programming specialist in creating agent-based models and simulations for use in discovery, learning and engagement in various areas of homeland security. He plays a significant role in creating next generation web based collaborative applications for research and training in areas including but not limited to homeland security, preparedness planning and exercise, business economics and supply chain management, human computer interaction, and computer science.

He is also responsible for giving technical presentations of on-going research at various conferences and seminars across the nation. Being involved in research and development, he also helps write various research proposals, papers, and publications.

He received his B.S. degree in Computer Science from Purdue University in 2003. His areas of interest include Modeling and Simulation, Software Engineering and Distributed Computing, Human Computer Interaction and Data Visualization, and Information Technology.

Angela Mellema has worked for the SEAS lab since 2004, initially as a Graduate Research Assistant and eventually as a Research Associate. She has been involved in the design of 3D visualizations for many of the agent-based simulations developed at the SEAS lab, as well as contributing to writing of several papers.

She received a B.S. degree in Computer Science from Taylor University in 2003, and a M.S. degree in Computer Graphics Technology from Purdue University in 2005. Her areas of interest include 2D and 3D visualization, modeling and simulation.
