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.
I usually teach HCI graduate courses and some intro courses in our undergraduate program. I also keep most of the content for my courses available on the web. Some of the more recent course even have video podcast of my lectures.
Teaching this Spring 2015: CS 6724 Service Design, Ubiquity and Mobility.
This is the short list of my current students. These are the students that I am their advisor of record (in no particular order).
