Christof Wetterich (April 12, 1952 - ) is a German theoretical physicist.

He is known for researches in quintessence, Wetterich equation for Functional renormalization, Asymptotic safety in quantum gravity.

The development of the theoretical method of functional renormalization by Wetterich has found applications in many areas of physics, e.g. it provides a suitable framework to study quantum gravity (asymptotic safety),[1] Yang-Mills theories[2] and it was also useful in non-relativistic quantum systems like the BCS to BEC crossover where it bridges the two theories in a unified theoretical language.

[3][4] Wetterich is best known for his proposal[5][6] of dynamical dark energy or quintessence in 1987.

He has done fundamental work for the theoretical understanding of tiny masses of neutrinos[7][8] The method of functional renormalization relates macro physical structures to micro physical laws in a continuous way.
