Trajectory Privacy Preservation in Mobile Sensor Networks
(Advisors: Dr. Pissinou, Dr.Kim)
Mobile sensor networks are finding rapidly growing applications in a wide range of data collection applications, such as natural disaster forecasting, health condition monitoring, military reconnaissance, and traffic monitoring. Meanwhile, privacy is becoming an indispensable concern of these applications. This project targets an important but mostly untouched privacy issue: trajectory privacy preservation in mobile sensor networks. Mobile sensors, carried by users or vehicles, communicate with peer nodes and the base station through wireless media continuously. Therefore, trajectory information not only indicates the movement patterns of the sensors but also reveals personal preferences and habits of users. Trajectory privacy invasion could lead to several types of risks for users, including personal safety, consuming profiling, and interference attacks.
Natural Language Processing and Computational Linguistics
(Advisors: Mark A. Finlayson)
Prof. Mark Finlayson’s work intersects artificial intelligence, computational linguistics, cognitive science, and the digital humanities. His research focuses on the science of narrative (as a language object), including understanding the relationship between narrative, cognition, and culture, developing new computational methods and techniques for investigating questions related to language and narrative, and endowing machines with the ability to understand and use narratives for a variety of applications. Prof. Finlayson seeks highly motivated REUs and RETs to address important problems in this area, including building automatic natural language processing tools for extracting syntax and semantics; building user-facing tools for language corpus annotation, and collecting richly annotated corpora of stories.

We are interested in research on affect, emotion, and personality at the intersection of research in Artificial Intelligence, Human-Computer Interaction, and Robotics. Emotional systems in humans influence important cognitive processes such as salience determination, focus and attention, priority determination, interruption in an emergency situation, memorization and recall, goal generation, goal attribution, categorization, and preference. All these processes are important for intelligent systems with limited resources evolving in an unpredictable environment, including artificial ones (W. Clancey; N. Frijda; M. Minsky, D. Norman, A. Ortony, R. Picard, D. Rumelhart, H. Simon; A. Sloman; R. Zajonc).

How does culture shape our understanding of the world? What makes stories so powerful? How can computation shed light on these questions? Culture surrounds us and affects our behavior and thoughts in ways large and small. Narratives are everywhere, and we know of no culture or society that does not use it as a fundamental form of communication for activities as diverse as the explanation, education, and entertainment. The Cognac lab investigates these and related questions from a computational and cognitive point of view, and the unifying interest of researchers in the lab is the computational modeling of culture, narrative, language, and their interaction with cognition. For the purpose of scope, we construe culture in a broad sense, as any set of shared knowledge structures that mold the behavior of a group of people. Researchers in the lab conduct inter-disciplinary research spanning artificial intelligence, computational linguistics, cognitive science, and the digital humanities, and use techniques are drawn from machine learning, natural language processing, linguistic annotation, knowledge representation, computational inference to tackle key questions in this space, including: How is shared knowledge—commonsense and cultural—represented in language and narrative? How do people and how can machines extract this shared knowledge from data? And how do we apply these insights to achieve advances in machine intelligence, educational practice, health and medicine, social science theory, and the humanities?
