Find me online at:

I am a PhD student in the Human Computer Interaction Institute at Carnegie Mellon University where I am advised by Ken Koedinger.

Before coming to CMU, I was a graduate student in Computer Science at Arizona State University where I worked with Pat Langley and Jami Shah.

I also completed my bachelor degree in Computer Science and Mathematics at the University of Wyoming where I did work with Ruben Gamboa and Siguna Mueller

I use artificial intelligence and machine learning to model how humans learn and solve problems in educational environments. I use these models to better understand human learning, and to facilitate and guide the design of new educational technologies.

I am also interested in how computational models can be used in other areas, such as supporting designers in being more creative and helping people to better understand and improve their personal fitness.
