My junior research at the Institute of Biophysics of the Russian Academy of Sciences (Pushino-on-Oka, Moscow Region) was concentrated on a study of mechanism of the self-oscillating chemical reactions that was lately named as the Belousov-Zhabotinsky and the Bray-Liebhafsky periodical chemical reactions. The discovery of self-oscillations in homogeneous media was undoubtedly a matter of luck: in this system, oscillations exist within a too narrow domain and monotonic behavior is much more likely. First time we used the continuous-flow reactor for that purpose. Introducing the new catalyzers the spatial system dynamics was observed in Petri dish: dissipative structure formation, importance of initiation centers, and negative and positive role of mixing intensity on a process rate. After changing a place of work (Water Problems Institute, Moscow) the biological wastewater treatment processes were studied by me many years using mathematical modeling.  Since early 90th  modeling of anaerobic digestion process  was carried out as a primary scientific interest. As a result the first user-friendly model was developed: ( http://www.methane.da.ru ). To model chemical and biological decomposition of solid waste the 1-3 distributed models were created recently. The various assay and lysimeter data were used for model calibration. The different phenomena of spatial dynamics during MSW degradation (importance of initiation methanogenic centers, negative and positive effects of mixing on a process rate, phthalate esters transformation in methanogenic conditions, etc.) were studied.
