PhD research topic
Diversity and assembly of a sub- tropical grassland community in eastern Himalaya
Supervisor: Dr. Robert John Chandran

Broad research interest
Ecosystem ecology and interdisciplinary approaches for biodiversity conservation

My main aim is to understand the resilience and sustainability of natural processes along with anthropomorphic pressure to the ecosystem. I am working in North East India, which comes under the Eastern Himalayan and Indo-Burma Biodiversity Hot Spot, stands out as being globally important for biodiversity.

The matrix of riverine grasslands and grassland-forest mosaics in the Ganges and Brahmaputra river valleys in the eastern Himalayan foothills are some of world's tallest and most productive grassland ecosystems .These tall grassland forest mosaics are the last remaining examples of subtropical tall grasslands in the Indian subcontinent, and contain some of the highest densities of tigers, rhinos, and ungulates in Asia. These grasslands mosaic are maintained by a suite of disturbance processes including flooding, fire, and grazing. My study site is Manas National Park, a world heritage site and a tiger reserve with an area of 519 sq. km, situated in the North bank landscape of Assam. As part of my doctoral study, I am doing landscape level surveys and also conducting experiments at smaller scales to provide insights into how different perturbation regimes influence plant species composition, richness and diversity in Manas. This study is providing an explicit opportunity to understand the mechanisms behind the process like succession, community structure and assemblages and to develop a set of effective management strategies for the optimal conservation of biological diversity.
