  Project 1: Led a cosmology project on unifying Early and Late Dark Energy models using dynamical systems and scalar fields. This involved:• Modifying CLASS cosmological solver through C and Python codebase adaptations.• Significantly improving computational efficiency on supercomputer clusters with more than 10x fold.• Executing Bayesian inference, MCMC, and nested-sampling algorithms for high-dimensional degenerate parameter analysis.• Developing a dynamical systems model to simulate universe evolution, resulting in a publication currently under review."Project 2: Developed a modified gravity theory altering Einstein's gravity to study the changes to the neutron stars' structure.• Proficiency in tensor calculus to interpret Einstein’s modified gravity equations.• Application of advanced numerical methods (shooting and relaxation algorithms) to solve complex boundary-value problems.• Algorithmic analysis for understanding gravitational interactions and predicting neutron star characteristics.
