My work in the foundations of physics is based on the idea that a matter-antimatter repulsive gravity is possible if the smallest possible massive systems (e.g. systems made up of a single electron, positron, free nucleon, etc.) alternate between a particle state and a wave state: during each individual process of alternation such a system interacts with the gravitational field in its environment, which is encoded in the metric tensor field, and the impulse that the system then receives by such a gravitational interaction then depends on the nature of its component. That being said, there are no known physics by which a smallest possible system can alternate between a particle state and a wave state, but in my PhD project I have identified a collection of process-physical principles that describe, without reference to any coordinate system of an observer, the elementary processes at supersmall scale by which the smallest possible massive systems alternate between a particle state and a wave state. I've called this set the ‘Elementary Process Theory’ (EPT): it has to be viewed as a scheme of first principles that underlie a matter-antimatter repulsive gravity.

From a mathematical perspective the EPT is a very simple theory, even though the formalism of the EPT might look cumbersome at first sight. This simplicity, however, is deceptive. The EPT, namely, is not only rather abstract, but it also yields a world view that entails a drastic departure of the world view of modern physics: the physical world at supersmall scale — we can think of this as the Planck scale — is not described in terms of

My main research interest is to prove that the four fundamental interactions (gravitational, electromagnetic, strong, and weak) as we know them can take place in the processes described by the EPT. The first question, however, is

Recently, I have applied this method to show that the EPT agrees with Special Relativity (SR): I have fully specified a model of the EPT that incorporates SR. This model is, in fact, a category consisting of

- a collection of objects, each of which corresponds to a set-theoretic model of the EPT in the coordinate system of an inertial observer;
- a collection of arrows, each of which corresponds to a coordinate transformation that transforms one set-theoretic model into another
