        Professor, University of North Carolina at Wilmington

Professor at UNC-Wilmington (2004-present) in the Department of Computer Science at the University of North Carolina at Wilmington.   Teaching and developing curriculum for undergraduate computer science education with an emphasis on innovative methodologies and educational technologies.    Leading research in natural language processing, virtual humans, intelligent user interfaces, membrane computing, human-computer interaction, and philosophy of artificial intelligence. 

Principal Investigator, Interactive Virtual Humans, RTI International

Principal Investigator at Research Triangle Institute (1995-2004) on a National Science Foundation Grant leading the development of interactive virtual humans with emotions that affect their body and facial gestures, decision-making, and language generation. Program leader of RTIís AVAtalkģ technology creating responsive, individual virtual humans ( In an AVAtalk-enabled application, users carry on spoken conversation with a simulated person (an avatar) and see and hear realistic responses from the avatar. 

Adjunct Assistant Professor, duke University

Instructor and advisor in the Department of Computer Science at Duke University (1994-2004).  Teaching includes two classes in Methodologies of Artificial Intelligence, a senior-level course, and Mind and Computers, a class in Dukeís exceptional Honors Program for incoming students.    I have sponsored graduate students through DoD and NSF contracts and worked closely with graduate students as committee member and co-author of research publications. 

Spoken Natural Language Dialog Systems

Research Engineer at Research Triangle Institute leading the development and integration of natural language dialogue into computer-based training and operational environments.  Funded primarily by STRICOMís ACT II Program, I led the development of a system that allows a trainee or mechanic to talk to a computerized assistant in a virtual reality environment during the diagnosis and repair of equipment. These systems have been implemented on a wide variety of platforms include off-the-shelf personal computers, wearable computers, hand-held computers, and high-end workstations.  Specific project domains include maintenance of the M1A1 Abrams tank, orientation training for ship engineering officers, flight training, and point-of-sale tasks.

Human-Computer Collaboration

As Adjunct Assistant Professor at Duke University, working on NSF and ONR- funded research on natural language dialogue in multimedia environments.  Created and implemented a computational model of collaborative problem-solving where individual participants communicate by natural language dialogue. This work focuses on determining what dialogue behaviors are necessary for completeness, soundness, and efficiency in cooperative problem-solving. Particular emphasis is placed on dialogue solutions to conflict resolution. The collaborative model synthesizes many AI modules: planning, user models, plan recognition, negotiation, variable initiative, and dialogue. This work serves as a test bed for ongoing and future research in human computer collaboration at Duke University.

Multimedia Tools for Education

Conducted research with Alan Biermann in the design of multimedia applications for teaching the relationships among fundamental concepts in Computer Science:  machine architecture, assembly language, higher-level languages, and compilation.  Worked on a team that created software that was used in Duke University Computer Science courses and made freely available over the internet. 

Text Abstraction

Co-adviser to Amit Bagga (PhD 1998) and Joyce Chai (PhD 1998) on a large corpus text abstraction project at Duke University that investigates the automatic extraction of semantic network knowledge representations of free-form English text in an electronic news domain.

Argumentation Theory

Designed and implemented a model of argumentation that exploits the relationship between high-level discourse phenomena and low-level syntactic phenomena in its processing of natural language utterances.

Expert Systems

Conducted research in conjunction with IBM on developing sales advisory systems.

Semantic Networks

Conducted research with Terry Nutter (Virginia Polytechnic Institute and State University) in semantic networks. Ported a semantic network and deduction system (SNePS) to a Symbolics machine.
