Research Fellow - Agentic Reasoning SLM

Undergrad Research and Innovation (URI)

Building the specialized reasoning brain of an agentic system while letting conversational models handle user interaction. Training a 3B parameter SLM architecture for one-step reasoning and tool selection. Constructing mathematical logic and proofs dataset as well as logic puzzles dataset. Integrating lightweight adapter layers (LoRA) and Reinforcement Learning to specialize the model for structured business workflows.

Sep 2025 - Present
AI/ML Product Engineering Intern

Apple

Architected multi-agent orchestration system integrating the Apple Foundation Model (AFM) with Model Context Protocol (MCP), implementing GraphRAG and Source of Truth algorithm. Designed tool selection, execution, and deployment with Basemind (LangGraph) using TouchID as Human in the Loop validation for deterministic agent behavior in Apple Pay Agentic Payment flow. Presented prototype to higher leadership demonstrating the Agentic Shopping experience and potential of AFM for Apple Pay.
