About me

Research interests: My primary research interests are in computer graphics, especially in animation and perception of virtual characters. I am furthermore interested in virtual reality, machine learning, and human-computer interaction.

Past positions:I received my PhD in 2011 from the Graphics, Vision and Visualization Group at Trinity College Dublin, Ireland, advised by Carol O'Sullivan. I then spent a year as a postdoctoral researcher at Carnegie Mellon's Graphics Lab working with Alla Safonova and Jessica Hodgins. 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.
