Peter Comba is Professor of Inorganic Chemistry at the University of Heidelberg, Germany. He obtained his diploma in chemistry from ETH and his Ph D in 1981 from the University of Neuchatel, Switzerland. After postdoctoral positions at the Australian National University (ANU) and the University of Lausanne and the habilitation at the University of Basel, he moved in 1992 to Heidelberg.
He received the Humboldt South Africa Research Award in 2000 and had visiting professorships at the universities of Leiden, ANU, Pretoria, Brisbane and Osaka. His research includes theory and experiments in transition metal coordination and bioinorganic chemistry – molecular modeling, spectroscopy, thermodynamics, magnetochemistry, kinetics and mechanisms, synthesis and catalysis.
