# Claes Uggla

is a professor of theoretical physics at Karlstad University. His current main research interest is the physical applications and mathematical features of general relativity, from how the properties of matter influence spacetime geometry to how strong spacetime curvature affects matter, and spacetime itself. For Einstein Online, he has written a spotlight text dealing with one of the most disturbing features of Einstein's theory of gravity: Spacetime singularities.
