I am a co-author with Walt Savitch on the following introductory C++ and Java Textbooks.
I have been at UAA since August, 2000. Prior to life at UAA I have worked at the following institutions:
Eye Tracking. We have been investigating the use of eye tracking technology for many purposes: secure authentication, collecting user data for information management, and analyzing student performance on gaze-related tasks (e.g. speed reading, air traffic control). As a first step to some of these projects we have created a C# wrapper for EyeTech's TM3 eyetracker. We also have plans to use eyetracking to support research projects in Psychology and Experimental Economics.
Agent-Based Simulations and Complex Systems. Some problems are too complex to solve analytically in a top-down fashion. The best way to understand them is through the bottom-up interaction of agents. This work uses the complex systems paradigm to explore various biological and ecological systems. For example, by simulating the foraging behavior of herbivores or the predator-prey interaction between killer whales and pinnipeds, we hope to better understand how to model and manage these resources. Another project is modeling the dynamics of killer whale populations. We have recently purchased an nVidia Tesla workstation with 480 GPU's that we hope to utilize for parallel simulations.
Authentication Schemes Resistant to Shoulder Surfing. A serious security problem is divulging your password to an attacker. The password may be revealed in a manner as simple as the attacker watching over the shoulder of the user entering their password. This work examines techniques to reduce or eliminate the shoulder surfing threat through novel authentication methods.
Visualizing Attrition in Computer Science. Our CS program suffers from high attrition. Where do students go that start in CS1? We have collected transcript data from all students starting in CS1 and developing visualization algorithms to see where they go and how far they get in the CS program.
Heuristic Search. Empire-based games are games where multiple units may move simultaneously in one turn. This results in a prohibitively large search space for traditional algorithms. This work explores hierachical organization, aggressive pruning strategies, and agent-based modeling to find ways to create an effective and adaptable computer opponent for these types of games.
Data Mining and Visualization of Faculty Expertise. We have constructed an online database for UAA faculty to submit their annual activity report. These reports contain data that describes the teaching, service, and research that is performed by our faculty members. We hope to mine this data so that it is possible to visualize what expertise exists on campus and create agents to allow users to automatically find faculty with expertise in a particular area while suggesting areas for collaboration.
