Bayesian Data Analyst | MCMC, Nested Sampling, JAX/Python | Inference & Uncertainty Quantification

Profile Summary

I am a researcher and scientific data analyst with deep expertise in Bayesian statistical inference, probabilistic modelling, and high-performance scientific computing. My core strengths lie in designing and implementing MCMC and nested sampling pipelines (dynesty, emcee) for parameter estimation, model comparison, and uncertainty quantification across complex, multi-dataset problems. I work primarily in Python and JAX, building efficient, differentiable inference pipelines that integrate ODE solvers, likelihood models, and posterior diagnostics. My experience spans the full data analysis workflow — from physical model design and numerical implementation to posterior sampling and publication-ready result interpretation. I am comfortable working with noisy, real-world scientific datasets and translating domain-specific problems into rigorous statistical frameworks. Whether you need a Bayesian model built from scratch, an existing pipeline debugged and optimized, or posterior results carefully interpreted, I can deliver reliable, well-documented solutions. I am available for freelance collaborations in physics, engineering, bioinformatics, and any field requiring rigorous statistical data analysis.
