**Background**: *Life manifests itself through complex dynamics across many scales, from â€œwiggling and jiggling of atomsâ€ (protein folding) to transcription dynamics in gene regulatory networks, disease dynamics and population dynamics. Advances in experimental techniques resulted in availability of multidimensional, time-resolved data about dynamical processes. On the other hand, advances in computer hardware and simulation algorithms made it possible to obtain detailed dynamical picture of real-life biological processes on a computer. Computational experiments became a vital component of researches arsenal, as was highlighted by the recent Nobel prize awarded to three computational chemists.
The large size of datasets generated by computer simulations or experiments makes the development of automated analysis tools very important, practically and conceptually. In our lab we focus on the development of an original state of the art approach which focuses specifically on accurate description of the dynamics and its application to the analysis of in-silico and in-vitro data.*
