Damianos Chatziantoniou
Assistant
Professor at Department of Management
Sciences and Technology,
Athens University of Economics and Business.
Prior to
AUEB I was a faculty member of the CS
Dept. of Stevens Institute of Tech.
I got my
Ph.D. and M.Phil. from the CS Dept. of
Columbia University (in databases – of course!)
M.Sc. from
the Courant Institute of Mathematical Sciences
– New York University and
B.Sc in
Math from the Math Dept. of University of
Athens.
My research
interests involve: OLAP, data warehousing, data streams, decision support
(mainly
expressing/evaluating complex ad hoc queries) and query processing.
Furthermore, I am very interested into
entrepreneurial-related stuff: I have been involved in
a couple of technology start-up companies, one based in New
York (Panakea Software Inc.,
OLAP tools & consulting, founder) and one based in
Athens (VoiceWeb, speech & telecom
applications, co-founder) and recently I spent few months at Aster Data Systems, in SF.
