I am an AI/ML and Quant Engineer, passionate about building systems where machine learning meets market intelligence. Currently, I serve as Chief of Staff and Founding Engineer at Silicon Data, a DRW-incubated spin-out backed by Jump Trading, where I lead initiatives in GPU pricing, token analytics, and data infrastructure. My research sits at the intersection of LLMs, reasoning agents, and world-model simulation — working with Prof. Zhou Yu at Columbia University and Arklex.ai to design agents capable of imaginative reasoning and code execution. Previously, at Cornell NLP Group (Prof. Alexander Rush), I worked on generation-augmented retrieval systems, contrastive learning, and large-scale alignment for LLMs.
