I am a postdoctoral researcher at Carnegie Mellon's Graphics Lab working with Alla Safonova and Jessica Hodgins. I received my PhD from the Graphics, Vision and Visualization Group at Trinity College Dublin, Ireland, advised by Carol O'Sullivan. During my PhD, I also conducted research as a visiting student in the Graphics Lab at Carnegie Mellon University and as an intern at Disney Research, Pittsburgh.
My primary research interests are in computer graphics, especially animation and perception. I am also interested in machine learning, game design, computer vision, neuroscience, and human-computer interation.My current research focuses on:
- Character animation techniques and algorithms. I am particularly interested in developing new animation techniques using motion capture, statistical properties and learning through databases.
- Perception of lifelike virtual humans. Humans are capable of successfully distinguishing between human and computer-generated motions, even if the differences are marginal. This skill makes it a challenge to produce convincing animations, especially for very realistic human-like virtual characters. I aim to determine which components of human motion are crucial to lifelike appearance and which errors diminish this realism.
- Hand and finger motions. Hand and finger motions are omnipresent in daily life. Nevertheless, virtual characters often lack convincing hand and finger motions. Capturing, analyzing, understanding, and automatically generating these subtle movements are topics I address in my research.
