My main interest is in constructing a theory of quantum gravity.
Quantum gravity is the theory that unifies the quantum mechanics which describes microscopic phenomena and general relativity which describe where gravity dominates, and it is expected that quantum gravity can explain the primordial universe where microscopic, but gravity is dominant. A complete theory of quantum gravity describing our four-dimensional universe, however, has not yet been established, and our understanding of quantum aspects of gravity remains far from complete.
As a basis for researching quantum gravity in four-dimensional spacetime, I am researching two-dimensional quantum gravity. Through the study of the two-dimensional case, I aim to gain insight into general properties of quantum aspects of gravity that are independent for the spacetime dimension, and to develop these insights into the progress toward constructing quantum gravity of the real world.
