PRINCIPAL RESEARCH INTERESTS

Paleomagnetism and its applications
  • magnetic record of paleoclimate
  • rock magnetic record of the Asian monsoon preserved in sediments of the Bengal Fan
  • application to tectonics
  • rock magnetic techniques for detecting and correcting paleomagnetic inclination shallowing
Tectonics of Asia
  • chronology and geometry of India-Asia convergence
  • configuration of the Asian margin prior to the collision
  • accretion of Gondwanan micro-continents to Asia
  • deformations in central Asia caused by the India-Asia collision
  • tectonic evolution of the Tibetan Plateau
  • Tethyan remnants in the Yarlung Zangbo suture and their geological development
ASSOCIATION MEMBERSHIPS
