Research

Database Systems

My past (and, to a certain extent, present) research interests include: database management systems (DMBSs) on modern hardware, algorithms for efficient query evaluation in main-memory, index structures for memory-resident data. This is all about how to make database systems faster on modern computers. My PhD thesis called "Efficient techniques for data indexing and query evaluation in main-memory database systems" attempts to address some of the problems in this area. I defended the PhD thesis under supervision of Prof. Boris Novikov, a well-known Russian expert in database systems.

Web Search

However, recently I've switched to such topics as information extraction from Web pages, integration of data from Web sources, Web data mining. I believe that despite undoubted progress of Web search engines in past years, Web search is still in its infancy. In particular, current Web search engines enable to find Web pages, while what people are really looking for is often information. How to collect and integrate information from diverse Web sources and present it in a comprehensible way to the user is a challenging problem. One particular task I'm working on is how to divide a Web page into meaningful content blocks and present in search results these blocks in place of mostly useless 'snippets' currently provided by search engines.

I published several research papers and have a DBLP record. More details can be found in my CV.

Conference Activities

I served on program committees and as an external reviewer at several conferences.

Industry

For 5 years from May 2003 till May 2008 I worked as a software engineer at JetBrains - a nice software company creating world-class Integrated Development Environments (IDEs) for different programming languages and environments. My industry work had nothing to do with my research, but it was also very interesting, as the products of the company are used by thousands of people all over the world.
