Senior ML Engineer & Researcher
Applied ML researcher turning messy data into deployed models. I work on recommendation, forecasting, and the unglamorous MLOps that keeps them alive in production. PhD in ML, allergic to hype.

About
My PhD was on sequence models for healthcare time series — which taught me that the model is the easy part. The hard part is the data pipeline, the evaluation that doesn't lie to you, and the deployment that survives contact with reality. I've since built recommendation and forecasting systems serving millions of users, and I've learned to be deeply suspicious of any metric that only improves offline. I publish when the work is genuinely new, and I ship when it genuinely helps.
Build models that are honest offline and useful online.

Kind words
“Priya's instinct for what will actually move the metric — not just the loss curve — is unmatched. The ranking win was one of the biggest of the year.”
