Matti Pitkanen is Finnish theoretical physicist. Since 1978 he has worked with Topological Geometrodynamics (TGD), which is a proposal for a unification of fundamental interactions generalizing string models. After the thesis on the subject (1982) he has continued as a free researcher to develop mathematical theory around the basic physical ideas represented in thesis. During nineties p-adic physics, quantum theory of consciousness, and quantum biology became parts of TGD program. Around 2005 the hypothesis about hierarchy of Planck constants led to a further generalization of the basic mathematical framework of TGD.
