Education:

B.S. and M.S. – University of Cologne, 1994
Ph.D. – University of Cologne, 1997

Research Interests:

Mineralogy of extreme conditions with emphasis on mineral chemistry of the deep Earth (transition zone and deeper) and processes during large asteroid impacts. I examine the rare, (sub-) microscopic natural occurrences of such phases and obtain in-depth information about their crystal chemistry and thermodynamics beyond what is realistically achievable in experiments. Thus, mineralogy of extreme conditions complements experimental high-pressure geo/mineral-physics.
