Gauge theories in elementary particle physics. Forces among elementary particles are either very weak, or they must be mediated by gauge fields. These fields are based on the same mathematical principles as the electro-magnetic force fields, but more complicated, and hence more interesting.

Quantum gravity and black holes. Whenever particles are separated further than 10-33 cm, the gravitational force between them is very adequately described by Einstein's theory of general relativity. But when they come closer, the gravitational force becomes strong, whereas gravity is more complicated than gauge theories. Finding a logically coherent theory telling us how particles behave at such small distance scales is a fundamental problem. The most dazzling problem is the question whether these particles will make microscopic black holes. Predicting the behavior of such tiny black holes is a deep theoretical challenge. Or maybe they can't form black holes? Formulating laws of physics that avoid black hole formation is even more difficult.

Fundamental aspects of quantum physics. I have deviating views on the physical interpretation of quantum theory, and its implications for Big Bang theories of the Universe. This topic has been expanded upon in my latest publication, entitled: "Quantum Gravity as a Dissipative Deterministic System"
