In India, varieties of different forest plantation methods are being practiced such as Miyawaki method, Monoculture forestry, Polyculture forestry, traditional knowledge-based methods and assisted reforestation of indigenous forests in order to mitigate land degradation.  

The primary objective of my thesis is to understand the dynamics of long-term carbon sequestration in tree biomass and soils of afforested and reforested tracts obtained through different forest plantation methods in comparable eco-regions in peninsular India. We plan to quantify carbon sequestered in above- and below-ground biomass and estimation of top soil and deep-soil carbon in plots managed under different forest plantation methods over a spectrum of stand ages. The data gathered will be analysed for understanding of each of these plantations and stand management methods for carbon sequestration efficacy. Predictive analysis of using such methods for landscape restoration and long-term carbon storage and GHG dynamics will also be attempted. Our analysis will involve monitoring and measuring of various metrics such as species distributions, stand densities, stand locations and topography, water usage during stand establishment to arrive at the most efficient method based on eco-region specificity that offer the best outcomes for serving the various planting objectives. The study will inform future course of action regarding how to proceed with tree planting activities. Monitoring of soil and local micro-climate parameters are also envisaged as a long-term environmental data gathering and base-line analysis objective. The tree biomass estimation will be based on data collected from ground surveys, tree specimen and vegetation plot measurements and standard, non-destructive, empirical and allometric extrapolation methods.

Research Experiences and Internships

1) April 2019- June 2019- Summer Project: Hypothesizing the effects of Evolutionary Isolation of Hosts on colonizer phenotypes in temperate forest ecosystem: Comparative analysis with Island Biogeography.     

Advisor: Dr. Andreas Prinzing, Professor, Equipe Evolution Structure et Dynamique de la Diversité, Universite de Rennes 1, Rennes, France.

The research group is particularly interested in the effect of evolutionary distances between host (oak) trees and neighbours on the phenotypes of colonizers (caterpillars). The goal is to understand whether for a given species of host tree, phenotypes of colonizers change depending on the neighbouring trees. 
                                                      
2) January 2019- March 2019- Winter Project: Reconstruction of vegetation and evolutionary patterns of forest ecology of Gondwana basins (Master’s Thesis).                                      \

Advisor: Dr. Pauline Sabina K., Scientist-D, Department of Gondwana Palynoflora, Birbal Sahni Institute of Palaeosciences (BSIP), Lucknow, India. 
 
Deciphering the vegetation, climate and functional ecology of Gondwana Basin through geological time scale ranging from early Carboniferous to late Permian period. The study involves palynochronology & stratigraphic correlation of spores to reconstruct the patterns of forest colonization & diversification.
