My research and teaching interests are focused on the use of geomorphic, geochronologic, sedimentary, remote sensing, and numerical modeling tools to quantify surface processes, landscape evolution, active tectonics, and paleoclimatic changes. My goal is to understand the dynamic interaction between climate, tectonics, and landscapes, especially in tectonically active and environmentally sensitive regions. My projects involve extensive field data collection, including remote sensing and GIS mapping using unmanned aerial vehicles (UAVs) and high-resolution Structure from Motion (SfM) photogrammetry. I complement field data with geochronometric analysis in laboratories. I apply and develop various geochronometers, especially luminescence (e.g., OSL, IRSL) and cosmogenic surface exposure (e.g., Be-10, Al-26) dating techniques. I use these geochronometers for dating glacial landforms, Quaternary alluvial deposits, and earthquake event horizons. I also use these methods to quantify hillslope erosion rates and model sediment routing and depositional events.
