My area of expertise is clastic sedimentology and sequence stratigraphy with a special interest in the quantitative depositional architecture of both shallow and deep water sedimentary systems. My research focuses mainly on the use of outcrops as analogs to hydrocarbon reservoirs paying attention to architectural elements and depositional environments. I am also interested to link and extend the outcrop studies with subsurface datasets (wire line logs, seismic and core data) for sub-regional and regional studies. I have been using the laser scanning technology (LIDAR) and 3-D imaging systems (Sirovision) to investigate architectural elements in outcrops. I am also familiar with remote sensing image analysis and processing techniques applied to geologic problems. I have been involved in processing and interpretation of shallow water sedimentary successions with a focus on outcrop studies of deltas (Washakie Basin, WY) and shelf (tidal) deposits (Tremp-Graus Basin, Spain) and deep water turbidites (Pennsylvanian Jackfork Group, Arkansas).
