Magdalini Eirinaki is an Associate Professor at the Computer Engineering Department. Her research interests cover the areas of web mining and recommender systems and, in particular, on personalization, social network analysis and mining, aspect-based opinion mining, and social recommender systems. Her current research projects involve the exploitation of the abundant user-generated content available online, especially when social interactions, social content and/or connections exist.

Prof. Eirinaki has published several papers in refereed journals and international conference proceedings in the above areas. She received her Ph.D. degree in Informatics (Computer Science) from Athens University of Economics and Business in 2006 and has been affiliated with San Jose State since 2007.

She has served as the PC member, or Chair in multiple international conferences, including, among others, the IEEE Big Data Service 2015(track Chair), and the IEEE Big Data 2014 and 2013 conferences. She has also served as a reviewer in top-tier journals (TKDD, TKDE, TOIT, SNAM, etc.) and as a guest editor in the FGCS and Big Data Intelligence journals. Prof. Eirinaki's students have won national and local competitions, including the IBM-organized "Watson: The Great Mind Challenge" in (2nd place, 2014), and the SJSU student research competition (finalists - participated in CSU-wide competition, 2015). She has been awarded the "Distinguished Faculty Mentor" award by SJSU Research Foundation.
