Publication activity: Author of on average two to three academic articles a year.

Projects: as a researcher has participated in more than 5 European and Latvian research projects.

Supervised Doctoral, Master and Bachelor Theses (number): 1 Master thesis and more than 10 Bachelor theses.

Research fields/domains: Data analysis, statistical analysis, mathematical modelling and simulation (in transportation), machine learning.

Motto: “Any problem can be turned into opportunity”.

Project Type: Academic

Main Challenge:

The project is devoted to developing of non-traditional regression models, namely Markov-modulated linear regression for analysis of traffic flow and adjacent transport tasks and find algorithms for their parameter estimation for big data.
