Hi, I am currently working towards a PhD in the Department of Computer Science at Columbia University. My advisor is Jason Nieh of the Columbia Networking Research Center .

I spend most my time at IBM , where I've worked as a fulltime employee since 1984, most recently at the T.J. Watson Research Center .

I received my MS in Computer Science in 1989 from Rensselaer at Hartford , an extension of RPI , and my BS in Computer Science in 1984 from SUNY at Albany .

My personal interests include golf (10 handicap), site-seeing, listening to live bands (rock/folk) and you can often find me late nite at some local diner drinking hot cups-of-joe . I tried to play soccer once but didn't have much luck. I also head to Danbury, CT quite often to visit friends.

You can email me at dpo1@cs.columbia.edu or call me at

(212) 939-7038. My office is located in RM 487 which is the Network Computing Lab, the Computer Science Building, Columbia University.
