My research uses interdisciplinary methods to improve the design and implementation of educational technology, and then to understand when and why it is effective. Broadly, I am interested in research in intelligent tutoring systems, computer-supported collaboration, robotic learning environments, technology for the developing world, and human-computer interaction. 

I am excited to announce that in January 2019, I will be joining the University of Pittsburgh with a joint appointment as an Associate Professor in the School of Computing and Information and as a Research Scientist in the Learning Research and Development Center.

From January 2013 - August 2018, I was an Assistant Professor in the School of Computing, Informatics, and Decision Systems Engineering, one of the Ira A. Fulton Schools of Engineering at Arizona State University. Prior to that, I was a Computing Innovations Postdoctoral Fellow at Arizona State University with Win Burleson. I completed my PhD in 2010 at Carnegie Mellon University in Human-Computer Interaction, under the supervision of Ken Koedinger and Nikol Rummel. My undergraduate degree is a B.Sc. (Honors) from the University of Manitoba in 2004 in both Computer Science and Psychology.
