I have more than 30 years’ experience in hydrogeology, most of which was dedicated to development of numerical and analytical models for quantitative hydrogeology. During my work in the Institute of Geoecology of RAS, I have been participating and managing numerous groundwater studies for mining industry, nuclear plants, water supply and environmental assessments in Russia and internationally.I have been teaching and supervising many research students in St-Petersburg State University and St-Petersburg Mining Institute (Technical University). For the last 25 years I have been developing ANSDIMAT suite of computer codes that is currently the most used aquifer test interpretation software in Russia and Russian-speaking countries.
