Tracing the causal fabric of spacetime.

I connect operator-algebraic models of quantum causality with cosmological observation—and build physics-informed AI to reveal faint structure in massive scientific data.

“How can we trace the causal fabric of quantum spacetime within the macroscopic cosmic web?”

My work moves between mathematical structure, observable signatures, and computational tools. The goal is not merely to make AI faster, but to make it respect—and help uncover—the laws that shape physical reality.

04 · About

Mechanics taught me systems. Computer science taught me models.

I began in mechanical engineering before transferring to computer science, carrying a physical intuition for complex systems into machine learning. At Cambridge, I plan to bring those threads together through quantum gravity, computational cosmology, and physics-informed AI.
