About

I am a Data Scientist at ChampionX, an SLB company, where I build AI, machine learning, and physics-based models for the oil & gas industry. My work sits at the intersection of data science and physics, focusing on models that don't just fit data but respect the underlying physics of the systems they describe.

My technical foundation comes from a PhD at IIT Madras, where I specialized in computational mechanics, phase field modeling, and finite element methods. My doctoral research modelled the electrochemical response of Li-ion battery anodes using a coupled multiphysics framework, solving chemical diffusion under stress alongside electrochemical reactions.

Today, I bring that same rigor into industry. I enjoy problems where an engineering system has strong physics behind it but also messy real-world data, and where the right answer is rarely pure ML or pure simulation, but a thoughtful combination of both.

I am proficient in the open-source C++ FEM library deal.II, and have contributed a standalone phase field solver to its code gallery. I also improved simulation performance by ~60% through MPI parallelization using PETSc.

Research

Ph.D. Thesis
Electrochemical Responses During Lithiation of High Capacity Anode in Li-Ion Battery
Supervisors: Dr. Narasimhan Swaminathan & Dr. Gandham Phanikumar · IIT Madras

Developed a coupled multiphysics framework using phase field modeling to simulate the electrochemical behavior of Li-ion battery anodes during (dis)charging. The model captures chemical diffusion under mechanical stress, coupled with electrochemical boundary conditions via Butler-Volmer kinetics.

  • Demonstrated the impact of phase transformation, electrode size, and mechanical stress on electrochemical response through voltammogram analysis, covering both elastic and elasto-plastic deformation regimes.
  • Developed a generalized multi-phase field solver capable of handling multiple coexisting phases, including in-depth analysis of model parameters and their mapping to physical factors.
  • Applied the multi-phase field framework to the peritectic solidification problem, demonstrating its versatility beyond battery systems.
  • Implemented all solvers in deal.II (C++ FEM library) and contributed a standalone crystal growth solver to its public code gallery.
  • Achieved 60% performance improvement via MPI parallelization using PETSc-based wrappers in deal.II.
Data-Driven Modeling for Predicting Microstructural Properties of Li-Ion Battery Electrodes
Collaborators: Dr. Anand Agrawal & Dr. Narasimhan Swaminathan · IIT Madras
Developed a Gaussian process regression model to predict Li-ion battery electrode performance from microstructural features like grain size, eliminating the need for expensive full simulations. Generated voltammogram datasets using FEM solvers (deal.II) with Butler-Volmer boundary conditions, and created microstructure meshes using Microgen and GMSH. The probabilistic model provides interpretable, uncertainty-aware predictions for electrode design optimization.
