Since September 2015, I am an assistant professor at the Department of Computer Science, Aalborg University, Denmark. Previously, I was a postdoctoral researcher at the L3S Research Center under a supervision of Prof. Wolfgang Nejdl. My research interests are information retrieval, Web and social media mining, and Web archiving. In particular, I focus on the impacts of Web dynamics on search, e.g., terminology evolution, time-sensitive queries, and time-aware retrieval and ranking. At L3S, I was a work package leader of the EU-funded project ForgetIT. The goal is to develop approaches and technologies for intelligent preservation management, which keep the archived information concise, relevant and digestible by managed forgetting and contextualized remembering. I was also a member of ALEXANDRIA, an ERC Advanced Grant Project on Foundations for Temporal Retrieval, Exploration and Analytics in Web Archives. The ALEXANDRIA project aims to develop models, tools and techniques necessary to archive and index relevant parts of the Web, and to retrieve and explore this information in a meaningful way. In addition, I am interested in health-related search and analytics, e.g., early outbreak detection in social Web data such as Twitter messages. This work on medicine and healthcare applications is a part of the finished EU project Medical Ecosystem: Personalized Event-based Surveillance (M-Eco).

My PhD work was conducted under a supervision of Prof. Kjetil Nørvåg at the Data and Information Management research group, Dept. of Computer and Information Science, Norwegian University of Science and Technology (NTNU). The PhD study is a formal part of LongRec - Records Management over Decades. LongRec was a research project on persistent, reliable and trustworthy long-term archival of digital documents, with emphasis on the availability and use of documents. LongRec was initiated and coordinated by DNV, and performed in cooperation with NTNU, NR, and a number of business partners, with partial funding from the Norwegian Research Council.

On 24th of February 2012, I completed the trial lecture and thesis defense thus being awarded the PhD degree. The evaluation committee was composed of Prof. Franciska de Jong, University of Twente, The Netherlands, Prof. Fabio Crestani, University of Lugano, Switzerland, and Assoc. Prof. Trond Aalberg, NTNU, Norway.
