About me
I am Serafeim, a research associate in the Information Management Systems Institute (IMSI) of the ATHENA Research Center since 2014 and a software engineer at OpenAIRE AMKE since April 2022.
I received my degree from the Department of Informatics and Telecommunications, University of Athens, Greece, in 2012, my master's degree in Computer Systems from the same department in 2015, and my PhD in Computer Science from the University of the Peloponnese, Greece, in 2022.
My PhD dissertation, entitled "Data mining for scholarly information networks" was supervised by Prof. Christos Tryfonopoulos. During that period (2017-2022), I was also a member of the Software and Database Systems laboratory (SoDa.Lab).
I have extensive experience in EU and national research projects, while my research interests lie in the areas of data mining, scientific databases, scientometrics and big data management.
