Applying an interdisciplinary research approach that primarily relies on geospatial science and technology and relevant datasets and resources in conjunction with field-based datasets and techniques for a wide range of applications is central to my research philosophy. This includes integrating GIS, Earth Observations (satellite and aerial including UAV remote sensing), and other datasets and methods (e.g. direct and indirect subsurface data) for the following major areas of research concentration:
- Environmental application – address environmental problems as well as investigate the short- and long-term impacts of anthropogenic interventions on the environment.
- Natural hazards/disaster – impact assessment, monitoring, and mitigation activities.This involves investigating impacts of hydrometeorological and geological hazards/disasters through data fusion involving remotely acquired data (optical and thermal remote sensing (e.g. Landsat, MODIS, Sentinel-2), Synthetic Aperture Radar remote sensing (e.g. Sentinel-1, UAVSAR), elevation data (e.g. DEM/LiDAR)) and field/ground-based data and reports (e.g. USGS, NOAA/NWS).
- Earth surface deformation and change – investigate subtle as well as large-scale Earth surface deformation and change processes using Interferometric Synthetic Aperture Radar (InSAR) and other geodetic methods and datasets (e.g. GNSS), and identify the controlling factors through spatial data analysis.
- Hydrogeology – remote sensing and GIS tools coupled with field techniques and data used to investigate groundwater quality, potential, surface-groundwater interaction, etc. studies. I had worked as a Hydrogeologist in the (groundwater) industry for more than 8 years and I am applying knowledge gained from that experience to my current research.
