Hello! I am Ibón Guillén, a researcher in computer graphics who currently works as a Interim Professor at the Computer Science Department at Universidad de Zaragoza (Spain).

My work revolves around using computers to generate pretty, realistic images, building physically-based models and making sure they are computationally tractable. In some ocasions I work the other way around, and starting from real images I try to formulate models that explain the proccesses by which they were formed. My research got me a PhD on Computer Science under the supervision of Dr. Adrián Jarabo and Prof. Diego Gutiérrez.
