Hi. I'm Dumitrel Loghin. Or Dumi, for short.

I am currently a Research Fellow in the Database Systems Research Group at National University of Singapore, working with Professor Beng Chin Ooi.

I obtained my PhD in Computer Science from National University of Singapore in 2017, under the supervision of Associate Professor Yong Meng Teo. Previously, I obtained my Master degree in Advanced Computer Architectures from Politehnica University of Bucharest in 2012 and the Bachelor degree in Computer Science from the same university in 2010.

My research interests are in Parallel and Distributed Computing, Advanced Computer Architectures, Embedded Systems and, in general, the performance of computer systems.
