With an energy of a startup and a quality of world-class research institute, QCRI is a perfect place for scientists bent on impacting their field and society.

Research Focus at QCRI

Specializing in social media analysis and mining, Yelena’s work concerns the quantification of health and wellbeing signals in social media, as well as tracking of social phenomena including politics and news consumption. Recently, she co-edited a volume on the use of Twitter for social science in Twitter: A Digital Socioscope, and a special issue of Social Science Computer Review on Quantifying Politics Using Online Data.

Previous Experience

Previously, as a postdoctoral member of the Web Mining team at Yahoo! Research Barcelona, Yelena participated in the Linguistically Motivated Semantic Aggregation Engines (LiMoSINe) EU project. The design and evaluation of the resulting entity-based exploratory search system has been awarded the Best Paper Award at the ACM Conference on Information and Knowledge Management (CIKM) in 2013.

Prior to that, her PhD thesis at the University of Iowa concerned the design and application of sentiment analysis tools for mining a variety of social media discourses, including political speech.

Yelena has published widely on sentiment analysis and its application to social media and political speech. She has given talks on the subject internationally, including Yandex’s Yet Another Conference (Moscow) and American University of Beirut.
