Where Research Meets Engineering

Academic Track

I am a Master's student in Artificial Intelligence at the University of Pennsylvania. My research focuses on Large Language Models (LLMs) and Brain-Computer Interface (BCI), aiming to improve LLM reasoning, alignment, and interaction quality — building models that understand, respond, and collaborate with humans more effectively across modalities.

LLM Reasoning Model Alignment Brain-Computer Interface Multimodal AI

Industry Track

In industry, I work as a Machine Learning Engineer specializing in Large Language Model systems, building production-grade GenAI applications using vLLM, TensorRT-LLM, RAG pipelines, and agentic workflows. I design scalable LLM inference infrastructure and full-stack solutions across Azure, AWS, and GCP, integrating efficient serving, orchestration, and cloud deployment into real-world AI systems.
