I am a PhD student at the Interactive Computing Experiences Research Cluster of Excellence (ICE). I got a Master of Science in Computer Science from University of Central Florida (UCF) and a Bachelor's degree also in Computer Science from (ESPOL).

My research interest is on pen and touch based computing, 3D user interfaces and mixed reality. I am specially focused on how to best use augmented reality for intelligent tutoring systems.
