Research Interests
- Evolution of sedimentary basins and orogenic systems.
- Influence of tectonics and climate on erosion and sedimentation.
- Quantitative basin modeling.
- Physical depositional processes.

Brian's research focuses on sedimentary processes in modern and ancient basins. The overarching theme is to understand the stratigraphic signatures of tectonic and climatic processes using a multidisciplinary approach. Research involves geological field work, facies analysis, provenance studies, quantitative basin modeling, stable isotope geochemistry, Ar/Ar and (U-Th)/He thermochronology, and magnetic polarity stratigraphy.

Current research involves investigation of:
- dynamics of foreland basin systems (Andes Mountains, South America; North American Cordillera);
- interactions between tectonic and climatic processes in driving rapid exhumation (Eastern Cordillera, Bolivia);
- earliest stratigraphic signatures of continent-continent collisions (Iran; Tibet);
- growth of high-elevation extensional basins (Cordillera Blanca, Peru).
