Research Experience  

  • College of Engineering Guindy, Anna University, India (Dec, 2017 – April, 2020)

Carried out the following projects under Dr. Sanjeevi Shanmugam, Professor of Remote Sensing, Anna University

  • Mapped crude-oil leak affected vegetation, soil and water bodies in Thanjavur and Thiruvarur districts, south India using Sentinel – 2 satellite images
  • Comparative studies on land degradation in south India due to oil-leak and tannery effluents using Landsat and Sentinel – 2 images
  • Visualizing economic slowdown in India through satellite images
  • Extracting high resolution information (6m) of reservoir boundary from Landsat OLI images (30m) using Super Resolution Mapping techniques based on Ant Colony Optimization and Genetic Algorithm
