Working experience

I worked on “Substratum preference, resilience of new recruits and reef connectivity model in predicting coral larval distribution along the Gulf of Mannar Marine Biosphere Reserve” Indian coral reef ecosystem.

1. Trend in coral-algal phase shift and substrate preference coral recruits

2. Resilience of coral recruits against bleaching, macroalgae proliferation and sedimentation load

3. Predicting coral larval reef connectivity model in Gulf of Mannar Marine Biosphere Reserve, India

Activities in GDOU:

1. Course assistance from 2019 to 2022

2. Doing coral culture experiments on microplastics ingestion, and climate change studies.
