Research My research focuses on the Quaternary geology and geomorphology of tectonically
active mountain belts and their forelands. I am particularly concerned
with quantifying the timing, and rates and magnitudes of landscape evolution
in these regions to understand the dynamics and interactions between tectonics,
Earth surfaces processes and climate. This involves remote sensing, field
mapping, geomorphic and sedimentological analysis of landforms, and geochronology.
I have concentrated my efforts in two major geographic-tectonic regions:
the Himalayan-Tibetan orogen; and the San Andreas-Gulf of California Transform
System. These regions provide two of the best natural laboratories for
understanding the dynamics of and the interaction between geomorphic,
tectonic and climatic processes along active plate margins. Ultimately,
these studies provide analogs for understanding and modeling the evolution
of ancient mountains and transform systems. Owen, L.A., Finkel, R.C., Minnich, R. and Perez, A.* (2003) Extreme
