Research Experiences






Regional Geospatial analysis 

Created high-resolution population grid dataset that covers the entire CONUS using newly released Microsoft national building footprints, designed interactive user interface for data sharing and downloading, and coupled high-resolution population product with floodplains from different agencies to generate detailed profiles of 100-year flood exposure in the CONUS. (two papers under review)

Dynamics of Human Settlement Intensity in Hurricane-prone Areas from Nighttime Remote Sensing

Identified hurricane proneness using historical storm tracks, desaturated traditional DMSP/OLS nighttime remote sensing imagery using NDVI derived from AVHRR and MODIS, and explored the spatiotemporal dynamics of human settlement in areas with high hurricane pronesness in the CONUS. (one paper under review)

Sensing and Improving Disaster resilience through Social Media Data Mining (deep learning analytics)

Designed a visual/textual fused artificial intelligence to automatically classify disaster related social media leveraging state-of-the-art convolutional neural networks. (two published papers) 

Remote Sensing and Social Sensing in Rapid Flood Awareness and Inundation Mapping

Designed flood geostatistical models integrating remotely sensed moisture with socially sensed VGI to aid in better flood awareness and inundation mapping. (two published papers)

Energy Harvesting Scenario (solar and piezoelectric) using GIS based techniques

Case study: Georgia Tech campus

Determined the optimal locations to installed solar and piezoelectric materials using GIS techniques and estimated the potential energy generated and potential costs. (Master capstone project)
