*, Ph.D.

I have graduated from MIT and now work as an algorithmic trader. My new e-mail is [first name] at gmail dot com.

I amwas a graduate student advised by Professor David Karger and Professor Regina Barzilay. Maybe you would like to connect via Facebook or LinkedIn?

In my spare time I enjoy aviation (I am a licensed private pilot), golf (my handicap is embarrassingly high), and good food (as revealed by the extent of my stomach).
