# Unnati Nigam on Tal

## Headline

PhD \(Statistics\) IIT Bombay \| Probabilistic Time Series \| Gaussian Processes

## About

I am a PhD researcher in statistics working on probabilistic time series models for nonstationary and structured dynamical systems\. My work focuses on Gaussian Process modeling, with emphasis on quasi\-periodic structure, scalable inference, and uncertainty quantification\. I work on problems where statistical modeling meets real systems, including forecasting, control, and robotics\. My research includes developing fast likelihood evaluation methods, parameter estimation with confidence intervals, and producing reliable predictions under uncertainty\.
