Research interests

Argon Geochronology @

Determining when and how movement in the ductile zone of the Earth occur. Dating deformation and metamorphic events that occur at major zones of collision or extension during Earth's history.  Dating deformation and movement zones using Ar/Ar geochronology within the framework of structural geology and microstructure.

Present arenas: SE Asia (Palawan, Sulawesi, Northern Borneo); NW Himalaya (Tso Morari, Ladakh, Rhotang); Greece (Evia, Sifnos, Ios, Syros); European Alps.
