About me

I am passionate about solving complex problems. One of the most sophisticated phenomena in the nature is human cognition. I studied the way human organism interacts with the surrounding environment both from the theoretical point of view and for practical applications. Along the way I also had to learned data science methods and programming. What I usually do is: I gather the data, I analyze them, I interpret the results, and I have fun doing so.
