PhD. Candidate in Geography
MSc. in Environmental Science and Disaster Management (Mahatma Gandhi University, Kottayam, Kerala, India)
BSc. in Physics (Kuriakose Elias (KE) College, Mannanam, Kerala, India)
For my PhD, I will be working with Sentinel-3 imagery and try to develop regional remote sensing algorithms to define phytoplankton phenology and groups, especially harmful algae along the Strait of Georgia and Southeast Alaska.
- Bio-optical studies of coastal waters
- Remote sensing of phytoplankton functional types
- Optical properties of Algal blooms
- Developing remote sensing algorithm for coastal waters
