I am Associate Professor and Associate Department Head and Director for Graduate Studies 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 2014: CS 5714 Usability Engineering.
I do a lot of service in the department and professionally. I am currently program chair for the ACM 2014 Richard Tapia Celebration of Diversity in Computing conference, Vice-President of the board for the non-profit Virginia Network for Latinos in Higher Education (VALHEN), and a an active member of the Coalition to Diversify Computing (CDC).
This is the short list of my current students. These are the students that I am their advisor of record (in no particular order).
You can find me around the web at these sites... Sorry, some of them are more personal than others and thus blocked from public view.
