About Me: For the academic year 2011-2012, I am a visiting researcher at the Max Planck Instutite for Mathematics in Bonn, Germany. I hold an NSF Mathematical Sciences Postdoctoral Research Fellowship, and my supervisor is Johan de Jong. As you can see, I am also an artistic visionary in the field of web design.

Here is my CV.
