Tectonics of the continental lithosphere with a focus on field investigations

Our research focuses on the evolution of orogenic systems to understand continental deformation. We use methods of structural geology, geo/thermochronology, analogue material modeling, material sciences, petrology, and tectonic geomorphology. Regional field projects, which integrate these methods, are the cornerstone of our research.

  • Ultrahigh-pressure orogeny (Qinling-Tongbai-Dabie-Sulu)

  • Tectonics of Central Asia (Pamir, western Tian Shan, Tibet (Uzbekistan,Tajikistan, Kyrgyzstan, P.R. China, Afghanistan, Iran))

  • Lateral extrusion tectonics and core-complex formation in the Eastern Alps and the Carpathians

  • Tectonics of SE-Asia (especially Mynamar (Burma))

  • Early evolution of the Caribbean and megashears in Central America

  • Variscan tectonics of Central Europe and Mesozoic-Cenozoic geomorphology of the Erzgebirge and surroundings

Grants and Equipment

Active and Past Research Projects


  • Tibetan Plateau Formation: tracing material flow around the East-Himalayan syntaxis (DFG)

  • Collaborative Research projects TIPTIMON and CaTeNA: 'Pamir-Tian Shan monitoring program' (BMBF)
  • Tectonics of Myanmar and Yunnan (DFG)
  • Tectonics of Iran and Afghanistan (DFG)
