Dr. Tatiana Podladchikova specializes in the development of innovative approaches in estimation theory to extract
a useful knowledge from noisy experimental data, control and forecasting for broad range of space applications:
solar physics, space weather, navigation and biomedical research and the development of fundamental tools
for analyzing and solving a broad class of estimation problems. Often advantages of developed data exploitation
tools to solve one problem, in particular, approaches to predictive modeling, image recognition, noise statistics identification,
and dynamical state estimation in conditions of uncertainty, lead to progress in interdisciplinary applications.
Solar activity forecasting, space weather, detection of active events on the Sun to mitigate hazards of space accidents and their consequences.
Development of adaptive techniques for tracking of moving objects.
– Geomagnetic Storm Forecasting Service StormFocus
StormFocus service provides advance warnings about the future geomagnetic storm magnitude on an hourly basis.
The forecast is based on real-time solar wind and interplanetary magnetic field data, provided by DSCOVR spacecraft,
which is located in L1 Sun-Earth libration point 1 500 000 km in front of Earth.
– Updated medium-term sunspot number prediction service
A universal technique that improves medium-term sunspot number prediction methods as they are monthly updated
using the last available observations of smoothed sunspot numbers using adaptive Kalman filter (updated every month).
- Forecast of the auroral oval boundaries and aurora borealis on Yamal island
Forecast based on real-time ACE solar wind and interplanetary magnetic field data and provides estimates of geomagnetic latitudes
of poleward and equatorward boundaries of the auroral oval, and equatorward boundary of the diffusive aurora for the next hour
(updated every hour).

Short description: Forecasting the strength of the sunspot cycle is highly important for many space weather applications.
We introduce a method to reliably calculate sunspot number second differences (SNSD) in order to quantify the short-term
variations of sunspot activity. We demonstrate a steady relationship between the SNSD dynamics in the early stage of the
declining phase of a given cycle and the strength of the following sunspot cycle. This finding may bear physical implications
on the underlying dynamo at work. On the basis of the developed predictive indicator, at the early stage of declining phase
of cycle 24, we predict that the sunspot cycle 25 will be weaker.

Course “Experimental data processing”
The course introduces students to practically useful approaches of data processing for control and forecasting.
The focus is on identifying the hidden and implicit features and regularities of dynamical processes using experimental data.
The course exposes data processing methods from multiple vantage points: standard data processing methods and their hidden
capacity to solve difficult problems; statistical methods based on state-space models; methods of extracting the regularities
of a process on the basis of identifying key parameters. The course addresses the problems in navigation, solar physics,
geomagnetism, space weather and biomedical research.
