Biodata

I am currently a Research Fellow at the School of Computing, National University of Singapore, and a member of the Database Research Group. From 2004 to 2007, I have pursued a PhD degree (expected graduation - May 2008) under the supervision of Dr. Panos Kalnis. I have obtained a bachelor degree from the Computer Science department at "Politehnica" University of Bucharest, Romania in 2003. My honours project, "Object Communication Issues on the ALiCE Grid" was completed during an internship at the School of Computing, NUS.
