Biography

I am postdoctoral researcher currently working on quantum foundations, in particular, quantum theory on indefinite causal structures (see quantum SWITCH and process matrix formalism), and tools from nonstandard analysis to find a consistent mathematical framework of quantum theory.

Information on my research projects can be found here.

I was awarded my PhD in June 2018 from University of Vienna with the thesis focused on the intersection of quantum foundations (measurement problem, spontaneous collapse models) and high energy physics (mixed particle systems). Before my graduate studies at UV, I received degrees in physics at Taras Shevchenko National University of Kyiv with concentration in theoretical biological physics (statistical mechanics of DNA).
