Areas of scientific activity:

• system analysis and in magnetic and other geophysical and geological data studies;
• introduction of a new family of classification algorithms "Voting by the Set of Feature (VFS)" for studying dynamic recognition problems;
• hierarchic clustering of spatial geophysical and geodynamic objects using discrete mathematical analysis;
• original algorithms of time series anomaly recognition on the basis of the fuzzy sets theory and their application to volcano monitoring and to the analysis of gravity and geomagnetic data;
• new dichotomy classification algorithms with single learning class; pattern recognition system FCAZ (Fuzzy Clustering and Zoning) to determine areas of the highest seismic risk;
• construction of a mathematical model of recognition of possible strong earthquakes epicenters locations and their time stability as a basis for seismic zoning;
• recognition of possible strongest, strong and significant earthquake occurrence locations in seismic regions of the Earth and evaluation of their reliability using the models for dynamic pattern recognition;
• development and integration into a single network of a system of magnetic observatories in the Russian Federation, (the highest standard of quality INTERMAGNET), integrated by a common center for geomagnetic data acquisition and analysis.
