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.
