My research is dedicated to advancing scientific exploration through the lens of quantum information science and technology. Specifically, I focus on quantum simulation, employing a diverse range of platforms to tackle complex challenges in nuclear and high-energy physics. My focus extends beyond traditional boundaries, encompassing interdisciplinary investigations into condensed matter and atomic, molecular, and optical (AMO) systems. One of the key motivations driving my research is the opportunity to overcome computational complexity, a longstanding obstacle in the theoretical exploration of strongly correlated systems across various contexts. I am particularly fascinated by the innovative paradigms rooted in quantum information science, which offer fresh perspectives on both longstanding and emerging problems.

A central area of concentration in my work lies at the “entanglement frontier.” Here, I am actively engaged in developing analytical and computational tools to, for instance, understand thermalization and non-equilibrium phenomena in subatomic systems and beyond — even preceding the full maturation of quantum technology for precise simulation. Exploring quantum, thermal, and topological phases in interdisciplinary settings is another facet of my research, alongside random-measurement protocols and entanglement tomography. Additionally, I am working on the intersections of lattice gauge theories and quantum error correction.
