I am a mathematician-engineer, my field of activity is mathematical modeling. I am a Doctor of Technical Sciences. My research papers are presented on https://ivanova-a.github.io. I have extensive experience in modeling temperature fields with the phase transitions in the continuous casting of metals and alloys. I also have experience in modeling the economic structure of society under the influence of rank exchange. My researh interests are: industrial mathematics; modeling of metal continuous casting; inverse problems; control theory; model based predictive control for control system design; mathematical methods in economics. Also I am interesting in blockchain technology and data analisys.
