Intelligence, out in the real world.

I’m a Computer Science student at Purdue, working on machine learning, perception, and robot control. I build systems that turn what robots see into what they do.

01 / Research & current work

From understanding
to action.

How do robots perceive their surroundings, learn useful behaviors, and act reliably beyond the lab? That’s the thread through my work.

NeurIPS — Neural Information Processing SystemsResearch publication
Accepted at NeurIPSVLA · Interpretability

Mechanistic Interpretability and Steering of VLA Models Through Sparse Autoencoders

Understanding what Vision-Language-Action models learn, and how we can steer their behavior. Co-authored research on mechanistic interpretability using sparse autoencoders.

More about this work
  • Trained VLA models (Open-Pi, OpenVLA, ACT) for closed-loop robotic control from multimodal inputs — imitation learning and RL for policy refinement.
  • Built perception-to-action pipelines integrating RGB-D sensing, SLAM, and state feedback for real-time inference.
  • Conducted sim-to-real experiments analyzing generalization gaps, failure modes, and robustness of learned policies.
  • Built a real-world Connect 4 robotic system combining VLA policies with classical control (Purdue Robotics Day demo).
  • Co-authored research on mechanistic interpretability and steering of VLA models through sparse autoencoders (SAEs).
  • Working on hallucination mitigation in video models for World Action Models.

02 / In the field

Real robots.
Real learning.

The interesting part happens when a model meets the physical world. A few moments from building, testing, and figuring things out.

Taking research
off the bench.

A real-world Connect 4 system that brings learned VLA policies and classical control together. There’s nothing quite like a live demo to find out what actually works.

A closer look / Selected projects

robot perception

RealSense to Unity 3D Perception & SLAM Pipeline

I built a real-time RGB-D pipeline from an Intel RealSense D435i for 3D reconstruction, SLAM-based localization, and spatial mapping in Unity.

VLA + classical control

Connect 4 Robot Demo

I built a real-world Connect 4 robotic system that combined learned VLA policies with classical control for Purdue Robotics Day.

03 / Experience

Different problems. Same curiosity.

From scientific ML to social systems and aerial robotics, each experience shapes how I build.

Agentic ML workflows for scientific analysis

Build agentic ML workflows with LangGraph and DSPy for automated scientific analysis, instead of one-off prompts. Focus on reproducibility — traceable, repeatable model outputs that scale beyond a single analysis run.

LangGraph, DSPy, scientific ML pipelines

Event pipelines and graph-based interaction modeling

Software Engineer Intern — re-architected high-throughput event ingestion pipelines for product behavior data. Designed graph-based interaction models for large-scale prediction systems, bridging product engineering and ML.

UAV perception and control systems

Worked on sensor fusion pipelines for stable real-time UAV flight. Early robotics systems work before moving deeper into ML for robot control.

Tools for the job.

From training a policy to getting a robot to execute it.
