Cleotilde (Coty) Gonzalez, Ph.D. Associate Research Professor and Director of DDMLab Coty is an Associate Research Professor in the department of Social and Decision Sciences at CMU. She earned a Ph.D. in Management Information Systems from Texas Tech University in 1996. Coty's research program is motivated by the fact that decision making in the real world is more complex than what we have studied in the laboratory and more dynamic than what we can usually investigate with traditional research methodologies. Her research is embedded within a theoretical framework that emphasizes the role and development of experience, the similarity of contexts and the cognitive abilities of decision makers. Coty's research lies at the intersection of Behavioral Decision Making, Cognitive Psychology and Computer Science. She employs a wide range of research methods including laboratory experiments with interactive simulations, computational and cognitive modeling, field data collection, eye-tracking and functional Magnetic Resonance Imagery, fMRI. office: Porter Hall 223C web: http://www.andrew.cmu.edu/~conzalez/ e-mail: coty@cmu.edu phone: 412-268-6242 fax: 412-268-6938
Angela Brunstein, Ph.D. Post-Doctoral Fellow Angela is a Post-doctoral Fellow in the DDM Lab. She earned a Ph.D. in Cognitive Psychology from the University of Hamburg, Germany in 2001. Angela's interests focus on understanding the strategies people use for learning and problem solving in complex and dynamic situations. Angela's recent research aims to model in the ACT-R cognitive architecture how people learn to interact with complex displays and how they integrate feedback when performing unfamiliar tasks. office: 4609 Winthrop St. 1st Floor Suite email:angelab@andrew.cmu.edu
Lisa Czlonka, M.S.W. Research Associate Lisa Czlonka completed her undergraduate degree in Psychology and Theology from the University of Notre Dame. She earned her MSW from the University of Hawaii. Her previous research experiences focused on adolescents and families. From this background she brings an interest in studying interactional affects of personality type on learning and decision making. She is currently pursuing her MBA in the Tepper flextime program at CMU. As the former lab manager, Lisa's main responsibilities included collecting, recording, and analyzing data using experimental methods involving human subjects. Other ways she supported the DDMLab include maintaining the lab server and designing the web page. Lisa remains involved with the lab doing research on the PeaceMaker project. office: 4609 Winthrop St. 1st Floor Suite email: lczlonka@andrew.cmu.edu
Haritha Dasari Undergraduate Student Haritha is an undergraduate student at Carnegie Mellon University. She is pursuing a BS in Information Systems and a minor in Business Administration. She is interested in pursuing further education in the field of human-computer interaction, and is excited to be involved with the research of the DDMLAB. email: hdasari@andrew.cmu.edu
Varun Dutt, M.S. Doctoral Student Varun is currently a Ph.D. student in the Engineering and Public Policy department at Carnegie Mellon University. He earned a Master's in Rational Simulation in the Psychology Department at CMU in 2007 and a M.S. in Computer Science, Information Technology and Software Engineering in CMU's School of Computer Science in 2006. He had earned a B.S. in Computer Science and Engineering from Thapar Institute of Engineering and Technology, India, in 2004, and worked as a software engineer in one of India's top IT Companies, Tata Consultancy Services (TCS). The current focus of Varun's interests and research has been in the fields of dynamic decision-making, system dynamics modeling (and systems thinking) and modeling human decision making and cognition using the ACT-R modeling framework. Varun has applied himself to investigating problems concerning stocks (accumulations and depletions) and flows. Most importantly, he is interested in answering the question of how people make repeated decisions and why people face so much difficulty in understanding the feedback from decisions in simple problems concerning their day to day lives. Varun is the main tool developer in the DDMLab, developing software simulations and tools for data analysis. His goal is to apply his interests to the field of decision sciences, particularly to the area of dynamic decision making. office: 4609 Winthrop St. 1st Floor Suite phone: 412-268-9547, 412-628-1379 email: vdutt@andrew.cmu.edu web: http://www.andrew.cmu.edu/user/vdutt/index.htm
Wei Siong Neo, B.S. Doctoral Student Wei Siong is currently a Ph.D. student in the Social and Decision Sciences department at Carnegie Mellon University. He earned a Bachelor of Science degree with Highest Honors in Psychology from the University of Michigan in 2007. Wei Siong’s research interests, in general, encompass judgment and decision making, as applied to complex, dynamic, and real-world problems. He is interested in how different variables, such as cognitive processes, emotions, individual differences, and social contexts, affect learning and decision making. Wei Siong is also interested in examining the different strategies people adopt when controlling dynamic systems and allocating resources. In investigating dynamic decision making, Wei Siong makes use of several research methods including laboratory experiments, cognitive modeling, and neuroimaging techniques. It is his ambition to better understand human judgment and decision making from the behavioral, computational, and neural perspectives. office: Porter Hall 321 email: wneo@andrew.cmu.edu
Alex Persoskie, B.S. Doctoral Student Alex received a BS in psychology from Allegheny College in 2005 and is a doctoral student in the Behavioral Decision Research and Psychology program at CMU. Alex is working with Coty on projects that contrast the limited cognitive abilities of human beings with the nearly infinite complexity of the world they must navigate. In general, Alex is interested in how aspects of behavior often seen as "irrational" (e.g., contingent use of decision heuristics, changing tastes, emotions) can be adaptive for an agent of bounded rationality in a dynamic system. office: Porter Hall 321 phone: 412-728-8541 email: persoskie@cmu.edu
Lelyn Saner, M.A. Post-Doctoral Fellow Lelyn is completed his PhD in Cognitive Psychology at the University of Pittsburgh in Spring of 2008. He earned his M.A. in Applied Cognitive Psychology at George Mason University in Fairfax, VA. His general research interests include reasoning, decision- making, and problem-solving in naturalistic settings. He has done work on the use of analogies for reasoning, mechanisms of scientific discovery, human-computer interaction, and collaboration. Lelyn’s most recent research has been an examination of how people frame decisions in real-world situations. His work in the DDMLab is focused on modeling shared situation awareness among members of teams. office: 4609 Winthrop St. 1st Floor Suite email: lsaner@andrew.cmu.edu
Polina M Vanyukov, B.S. Doctoral Student Polina M Vanyukov completed her undergraduate degree in Logic and Computation at Carnegie Mellon University. She is currently enrolled in a Ph.D. program at University of Pittsburgh. Lina is the former lab manager, responsible for providing research support, namely, collecting, recording and analyzing data using experimental methods involving human subjects. She also maintained the lab server and designed web pages.
