As for me, I'm Dr. Nathan Yau, PhD, but you can call me Nathan. My dissertation was on personal data collection and how we can use visualization in the everyday context. That expands to more general types of data and visualization and design for a growing audience.
I've also written a couple of books on how to visualize data.
