Who Am I? (Visually speaking)

I'm all done with my Ph.D. and it's been a few years.  It's time I update my Wordle.net to see how I have changed and grown over the years.  (Why do this?  Well, we all talk a lot about how visuals are more effective, but many of us do not take the time to create the visuals. What I love about the slew of Web 2.0 tools is that they make the visualization process so easy. Of course, you can still read my CV for the full description of me and my skills, but you can also understand who--and what--I am at a glance, below.)
