Experience
Research Scientist
Dec 2021 — Present
Built a multivariate time-series churn model (Transformer-based) to reduce feature engineering and improve early-warning signals for at-risk users.(Paper: ICMLA 2023)Framed fantasy-cricket team selection as an RL problem; shipped DQN/PPO prototypes for squad creation under constraints.(Paper: Cods-Comad 2024)Modeled user journeys with DTMC/CTMC and an infinite mixture of Markov chains to discover segments and transition dynamics for lifecycle interventions. Additional work: hierarchical contextual bandits for personalization; graph-transformer models on temporal player graphs; synthetic data with Conditional GANs & diffusion. Hiring & research: Interview panel for Lead/Principal ML Scientists.
