Summary

Ph.D. in Computer Science, University of Pittsburgh. Research at Western Michigan University (WMU), Purdue University, and University of Illinois at Chicago (UIC). Teaching Computer Science at WMU and UIC. Tutorial instructor for IEEE Computer Society. Diversified R&D experience at AT&T/Lucent Bell Labs. Consultant for academic and business projects. Entrepreneurial experience in the United States and Poland.

Current research focused in two Areas: (1) opportunistic networks or oppnets (a specialized kind of ad hoc networks); and (2) trust, privacy and security in open computing systems. In Area 1, focus on primitives for oppnets, privacy and security in oppnets, and interoperability of oppnet helper networks and devices. In Area 2, concentration on vulnerability analysis and threat assessment, privacy-preserving data dissemination, authentication and privacy in health care, the role of trust in open computing environments, analysis of computer security paradigms, modeling computer fraud, and security and privacy aspects in pervasive systems, including ad hoc sensor networks and embedded networks

Former areas of investigation include: (a) distributed computing systems with concentration on decentralized control; (b) distributed database systems with focus on reliability, fault tolerance, recovery, concurrency control, query optimization, and database design; and (c) semantic database integrity.

Editorial Board member for the International Journal of Communication Networks and Distributed Systems, The Open Cybernetics & Systemics Journal, and Recent Patents on Computer Science (new journal). Chair and organizer of the International Workshop on Specialized Ad Hoc Networks and Systems (SAHNS 2007) in conjunction with the 27th IEEE International Conference on Distributed Computing Systems (ICDCS 2007). Co-PI for an NSF grant on vulnerability analysis and threat assessment/avoidance.

Senior Member of the Institute of Electrical and Electronics Engineers (IEEE) and IEEE Computer Society. Affiliated with the Center for Education and Research in Information Assurance and Security (CERIAS), and the Regenstrief Center for Healthcare Engineering (RCHE), both at Purdue University.

Research

Current Projects

· Opportunistic networks (oppnets)

Projects—mostly focusing on trust, privacy and security—include:

- Helper privacy and oppnet privacy

- Classic and identity-based authentication in oppnets, including authentication of helper candidates in oppnet environments, and authentication of oppnet nodes in oppnet environments

- Masquerading in oppnets, including malevolent hosts masquerading as oppnet member, and malevolent helpers masquerading as helpers or oppnet members

- Software agents' role for security and privacy in oppnets

- Intrusion detection, honeypots and honeyfarms in oppnets

- Semantic Web for agents’ trust in oppnets

- Security and privacy issues for Software Defined Radio in oppnets

· Vulnerability analysis and threat assessment/avoidance in computer systems, esp. in database systems

· Privacy-preserving data dissemination

· Authentication and privacy, with emphasis on authentication in healthcare systems

- Project Authentic: Authentication Attacks and Controls

· Using trust for entity authorization in open computing environments

· Analysis of computer security paradigms and development of new ones

· Modeling computer fraud and investigating types of fraudulent user behaviors

· Security and privacy issues in ad hoc sensor networks and embedded networks

This work has been supported in part by the National Science Foundation (NSF), the Center for Education and Research in Information Assurance and Security (CERIAS) at Purdue University, the Regenstrief Center for Healthcare Engineering (RCHE) at Purdue University, and DARPA.
