Associate Dean of Research and Graduate Programs; Professor of Computer Science
Anita Raja is Associate Dean of Research and Graduate Programs and Professor of Computer Science in the Albert Nerken School of Engineering at The Cooper Union. Prior to joining Cooper Union, she was an Associate Professor of Software and Information Systems at the University of North Carolina at Charlotte from 2003-2011. Anita received a B.S. Honors in Computer Science with a minor in Mathematics summa cum laude from Temple University, Philadelphia in 1996, and a M.S. and Ph.D. in Computer Science from the University of Massachusetts Amherst in 1998 and 2003 respectively.
Professor Raja oversees the graduate program, the study abroad program, the premed track and facilitates research activities of faculty and students in the Engineering School. She also directs the Distributed Intelligent Agents Lab. The lab consists of a team of undergraduate and graduate engineers doing research in artificial intelligence, multiagent systems and machine learning. Professor Raja also serves as a research mentor to several high school students from New York and New Jersey high schools. She has taught courses in Software Agent Systems, Distributed Artificial Intelligence, Network-based and Web-based Application Development, Advanced Object Oriented Design and Implementation, Physics Simulations and Engineering Design and Problem Solving.
Professor Raja's research contributions are in the field of Artificial Intelligence (AI), specifically as it relates to the study of decentralized control and reasoning in intelligent software systems operating in the context of uncertainty and limited computational resources. Along with her students, she studies the role of bounded rationality, meta-cognition and multiagent learning in decision support systems. Applications include traffic control, clinical informatics, tornado tracking, major defense acquisition programs, situational awareness in social media, e-government and public policy decision making, predictive and visual analytics for intelligence analysis, task allocation problems, intelligent information gathering and smart home technologies.
Her work is supported by grants from NSF, ONR, DARPA and DHS. Anita has co-chaired several workshops on Metareasoning and is co-editor of the MIT Press book titled Metareasoning: Thinking about Thinking. She is recipient of the 2006 UNCC College of Computing Essam El-Kwae Student-Faculty research award and Best Paper Award at the 2010 IEEE Intelligent Agent Technology Conference. She has served on organizing and program committees of several AI-related conferences and workshops and regularly participates in National Science Foundation grant review panels.

Advanced Machine Learning for Clinical Informatics
The multifactorial complexity of clinical data complicates prediction and prevention of undesired outcomes. This project aims to investigate the value of more advanced machine learning methods by simultaneously considering all the factors, to develop better predictive and prevention methods.

Emergence of Social Norms and Conventions in Multiagent Systems
In this project, we study the importance and challenges of establishing cooperation among self-interested agents in multiagent systems (MAS). The hypothesis of this work is that equipping agents in networked MAS with “network thinking" capabilities and using this contextual knowledge to form social norms in an effective and efficient manner improves the performance of the MAS. We investigate the social norm emergence problem in conventional norms (where there is no conflict between individual and collective interests) and essential norms (where agents need to explicitly cooperate to achieve socially-efficient behavior) from a game-theoretic perspective.

Decision Making in Partially Observable Environments
Design, develop and evaluate stochastic transition probability function, cost effectiveness analysis and sensitivity analysis to support decision making in uncertain environments. We will study this in the context of prevention of undesired outcomes in clinical informatics.
Coordinating Meta-level Control Across Agent Boundaries
The fundamental question addressed in this work is how to determine and obtain the minimal overlapping context among decentralized decision makers required to make their decisions more consistent. Our approach is a two-phased learning process where agents first learn their policies offline within the context of a simplified environment where it is not necessary to know detailed context information about neighbors. We evaluate our approach by addressing meta-level decisions in a complex multiagent weather tracking domains.

Modeling Cascading Risk in Interdependent Networks
Networked applications often operate under uncertainty in environmental response and the temporal state and action choices of the nodes are captured in the form of structured and unstructured text data as well as image data. We propose a network-centric approach that will contribute to advances in reasoning about uncertainty, large-scale text and image data analysis as well understanding of complex networks. This work is expected to lead to innovative extensions in the following research areas: combining topic modeling and information extraction from text data and image extraction for data foraging, identification of topological features for network analysis and studying the interactions between stakeholders at varying levels of the network. Specifically, we plan to study this problem in the context of Major Defense Acquisition Program (MDAP) network.

WLAN Management using DCOPS
This research investigates cooperative resource management in WLAN (wireless local area networks) /WPAN (wireless personal area networks) interference environments. The objective of this research is to manage shared system resources fairly among multiple WLANs to optimize the overall performance. Results from the project are expected to impact next generation WLAN network management based on employing algorithms of agent interaction and coordination to facilitate resource management, predictive models for parameter estimation, and dynamic load balancing algorithms.
