My current research interests include paleoaltimetry and paleohypsometry, past history of plate production and destruction, age of initiation of the India-Asia collision, modelling of global plate kinematics and links to geodynamics, long-term sea level variation and reconstructing global paleogeographic evolution.

    Field-based research focuses on the evolution of the Himalaya-Tibet Plateau, with a particular emphasis on paleoaltimetric estimates of its elevation history. This work is collaborative with Brian Currie (Miami University). My Chinese colleague  Erchie Wang, Associate Director to the Institute for Tibetan Plateau Research, Chinese Academy of Sciences has been instrumental in the field component of this collaboration, while Dan Schrag at Harvard has provided analytical support, and Ray Pierrehumbert (U of C) modeling and climate collaborations. In addition collaboration with Kate Freeman and Pratigya Polissar is developing new archival records from which to derive paleoaltimetry estimates. 

    I am a fellow of the Canadian Institute for Advanced Research-Earth System Evolution Program (CIFAR-ESEP) through which I have on-going collaborations with Alessandro Forte (UQAM), Jerry Mitrovica (Toronto) with joint CIFAR-Post-doctoral fellow- Rob Moucha (UQAM), and with Kate Freeman (Penn State) and joint CIFAR-Post-doctoral fellow - Pratigya Polissar (Penn State/UC Santa Cruz).

    In addition I have recently become the Editor of The Journal of Geology, published by The University of Chicago Press.
