Graduate student at UCLA

Intelligence, reasoning, and science.

I work on computational methods for scientific discovery, with interests in generative and physics-informed models, hybrid quantum-classical algorithms, and practical AI systems.

About

I am pursuing a Master of Quantum Science and Technology at UCLA. My current interests are in computational tools for scientific discovery, especially where machine learning, inverse problems, and quantum methods overlap.

Before UCLA, I led development of Reggi, a legal AI assistant at Regology. Earlier, I worked on communication-efficient distributed learning at KAUST and on optimization problems in research internships.
