About

Empowering innovation through 10+ years of dedicated expertise in Computational Research Science, I specialize in leveraging statistical techniques, mathematical modeling, and high-performance computing (HPC) to solve complex challenges across diverse domains. My expertise spans critical areas such as Theoretical/Computational Quantum Condensed Matter Physics, Computational Chemistry, Computational Material Science, Quantum Computing, and Data Analysis. With a proven track record in deploying advanced methodologies, including quantum teleportation (qubit transfer in spin networks), Quantum Monte Carlo Simulations, First-principles (ab-initio) calculations, and cutting-edge algorithms, I bring a robust foundation in both classical and quantum realms. I thrive on translating complex data into actionable insights, utilizing a spectrum of Machine Learning techniques—from supervised to unsupervised and reinforcement learning, encompassing Regression, Classification, Neural Networks, TensorFlow, and Recommender Systems.
