Research

RESEARCH INTERESTS

Lipid Biomarkers 

Tectonics

Geochronology

Stable Isotopes

Surface Processes 

Terrestrial Sedimentology

Tectonic Geomorphology

 

Integrated evolution of surface processes, rivers and lakes, tectonic, and climate. Landscape, vegetation and hydrologic change in response to tectonic or climate induced processes. Biogeochemistry and stable isotopes. Satellite data. 

My interest focuses on the complex feedbacks between tectonic, surface and climate processes. I take a field-based approach that entails geological mapping, structural and basin analysis, geochemistry combined with thermochronology, and cosmogenic nuclide dating to solve different aspects of spatiotemporal patterns of surface processes and their tectonic and/or climatic forcing mechanisms.

Aims of my research efforts to date include: (1) quantifying the dynamic relationships between tectonics and climate with respect to the development of mountain belts, plateaus and biodiversity, (2) deciphering process rates at a variety of time scales to better understand the discrepancies between long-term (i.e., geological) and short-term process rates of deformation, erosion and hydrology (3) studying active and inactive thrust belts to better understand changes of tectonic style, timing of deformation, uplift and erosion of foreland systems, (4) understanding the role of climate and vegetation in shaping mountain belts, (5) determine the rates of wind erosion processes, (6) the late Cenozoic tectonic and climate evolution of Asia and South America.

Most recently, I have been investigating tectonic and ecohydrologic conditions in NW Argentina during orographic barrier uplift and plateau growth, and studied the role of wind erosion in central Asia. At the moment I investigate the onset of early monsoonal conditions in East Asia and related eco-hydrological changes. In the future I hope to investigate more deeply terrestrial archives that hold valuable information of past tectonic activity, and its forcing of climatic and paleohydrologic conditions.

Integrated evolution of surface processes, rivers and lakes, tectonic, and climate. Landscape, vegetation and hydrologic change in response to tectonic or climate induced processes. Biogeochemistry and stable isotopes. Satellite data. 

My interest focuses on the complex feedbacks between tectonic, surface and climate processes. I take a field-based approach that entails geological mapping, structural and basin analysis, geochemistry combined with thermochronology, and cosmogenic nuclide dating to solve different aspects of spatiotemporal patterns of surface processes and their tectonic and/or climatic forcing mechanisms.

Aims of my research efforts to date include: (1) quantifying the dynamic relationships between tectonics and climate with respect to the development of mountain belts, plateaus and biodiversity, (2) deciphering process rates at a variety of time scales to better understand the discrepancies between long-term (i.e., geological) and short-term process rates of deformation, erosion and hydrology (3) studying active and inactive thrust belts to better understand changes of tectonic style, timing of deformation, uplift and erosion of foreland systems, (4) understanding the role of climate and vegetation in shaping mountain belts, (5) determine the rates of wind erosion processes, (6) the late Cenozoic tectonic and climate evolution of Asia and South America.

Most recently, I have been investigating tectonic and ecohydrologic conditions in NW Argentina during orographic barrier uplift and plateau growth, and studied the role of wind erosion in central Asia. At the moment I investigate the onset of early monsoonal conditions in East Asia and related eco-hydrological changes. In the future I hope to investigate more deeply terrestrial archives that hold valuable information of past tectonic activity, and its forcing of climatic and paleohydrologic conditions.
