      PhD in Physico-mathematical sciences probability theory and mathematical statistics, theory of Markov processes, queueing theory

      During my PhD research, I have been working on the investigation of doubly stochastic Poisson processes which are also known as doubly stochastic flows of events or Cox processes and are widely used in telecommunication networks, statistical modelling, quantitative finance, etc. I have performed a detailed research on two problems: flow states estimation and flow parameters estimation on monitoring the time moments of the events occurrence.

As a part of my project, I have developed and implemented the algorithms for both tasks by applying the criterion of a posteriori probability maximum, method of moments, maximum likelihood estimation, methods of mathematical analysis and simulation.
