Main highlights

Introduction: My name is Aleksejus Kononovicius (lt. Kononovičius). I hold PhD in Physics (for more details see here) and currently work as a researcher at Institute of Theoretical Physics and Astronomy (see here). Besides conducting research in Econophysics and Sociophysics, which involves stochastic and agent-based modeling as well as a bit of Data Science (see here), I also teach "Numerical methods I" course (see here). In spare time, when not skying, cycling or doing various geeky stuff, I blog about my and related research on Physics of Risk.

Recent papers I am most proud of (see the full publication list):

• Compartmental voter model. Most models in Sociophysics are observed over time, while the empirical data is quite often spatial. In this paper I have proposed a new kind of voter model, which evolves both in space and time. The proposed model is able to reproduce electoral and census data.
• Approximation of the first passage time distribution for the birth-death processes. In this paper we have proposed a method to approximate specific first-passage time distributions of the birth-death process. Approximation is needed, because these distributions are often expressed through Laplace transforms, which are quite often hard (or impossible) to invert. This paper also briefly touches upon the topic of the spurious long-range memory, which we argue to exist in the financial markets.
• Order book model with herding behavior exhibiting long-range memory. Here we have proposed a comparatively simple imitation driven model, which builds atop empirically validated order book model. The proposed model is able to generate return and trading activity time series, which are statistically similar to the empirical series.
