Position

Professor at the Department of Biochemistry, University of Geneva, Geneva, Switzerland.

Research interests

- cooperative oxygen binding and the structure of hemoglobin, especially the helical fibers of the sickling mutant, hemoglobin S (beta 6 Glu to Val),
- the structure and function of tubulin, especially from yeast, as well as microtubule associated proteins,
- detailed modeling of the kinetics of ligand-gated channels. An allosteric-type mechanistic model incorporating linear free energy relations to describe the effects of ligand binding on interconversions between conformations has been developed and applied principally to single channel data of the nicotinic acetylcholine receptor and certain myasthenic mutants.
