Jochen Kolb, research professor at GEUS since 2011, holds a PhD from RWTH Aachen University, Germany. He applies an integral approach to describing crustal fluid systems. With a special aim of describing different mineral systems, Jochen Kolb is interested in combining structural geology and petrology to study the interface between the various processes related to the formation of mountains.
In 2014 Jochen Kolb has joined the Geochemical, Mineralogical and Petrological Earth Processes research group as adjunct professor. With his adjunct professorship Jochen Kolb hopes to secure research in economic geology in his fields of interest and economic geology education in general at the University of Copenhagen and within the Geocenter Denmark.
Jochen Kolb has a special interest in disseminating his own interest in geology to students and has contributed to the completion of many master, ph.d. and post.doc thesises (see below). You are welcome to contact Jochen with inquiries regarding collaboration on projects.
