Welcome! I am a Human-Computer Interaction researcher currently at Lockheed Martin Advanced Technology Laboratories in Cherry Hill, New Jersey. I am a member of the User-Centered Interfaces Group, where I work on advanced user interface technologies such as spoken-language understanding, handwriting recognition, gesture recognition, and more. My general research interests involve the integration of multimodal technologies into cohesive, natural user interfaces for people using computers in a variety of tasks and environments. I focus on studying ways in which these technologies can provide benefits to potential end users by using design principles based on properties of human cognition and perception, and by working directly with the target population for a new system to design, develop and evaluate new interface and interaction paradigms.

Previously, I received my Ph.D. degree from the Human Computer Interaction Institute (HCII) in the School of Computer Science (SCS) at Carnegie Mellon University in Pittsburgh, Pennsylvania. My thesis work focused on the area of handwriting-based interfaces for intelligent tutoring systems for algebra equation-solving and was advised by Jie Yang and Ken Koedinger. In addition to an M.S. in HCI from Carnegie Mellon, I have a B.S. and an M.S. in computer science with concentrations in artificial intelligence, human-computer interaction, and software engineering from Drexel University in Philadelphia, Pennsylvania. For my M.S. thesis I used genetic programming to evolve board evaluation functions for computer agent players of the strategy game Acquire. Earlier research involved creating a computer-aided conceptual design tool for engineers called CUP.
