¡Bienvenidos! Welcome!

I am an Associate Professor in Computer Science at Virginia Tech. I am originally from Río Piedras, Puerto Rico but now reside in the beautiful mountains of southwest Virginia.

My research is in Human-computer interaction. Some areas of HCI that I have studied are in personal information management, information refinding, tools for building interactive systems, digital libraries, use of computers for education, and cultural influence in interface design.
