What separates classical from quantum?

I am currently an NSF MSPRF and IQUIST postdoc in the math department at UIUC. In January 2027, I will join the physics department at the University of Rhode Island. My research uses tools from physics, mathematics, and computer science to solve problems in quantum learning theory, quantum sensing, and entanglement characterization.

Research themes

The unifying goal of my research is to understand the power and limitations of quantum technologies, both current and prospective. This practical motivation leads to many interesting theoretical questions whose solution often involves tools from linear algebra, representation theory, and quantum information theory.

I.

Quantum learning theory

What resources are necessary and sufficient to learn/test properties of a quantum system? And how does the answer change when one's measurements are restricted by experimental capabilities?

II.

Entanglement theory & characterization

How can we use various mathematical tools to understand multipartite entanglement? Practically, how do we efficiently quantify multipartite entanglement when restricted to realistic measurements?

III.

Quantum sensing

Where are the fundamental limits on how precisely a quantum system can measure a signal? How do squeezing, entanglement, and non-demolition strategies actually perform in practice?

About me

In January 2027, I will join the Department of Physics at the University of Rhode Island as Assistant Professor. I am currently wrapping up a postdoctoral fellowship at the University of Illinois Urbana-Champaign, where I worked with Felix Leditzky as an NSF Mathematical Sciences Postdoctoral Research Fellow and an IQUIST Postdoctoral Fellow.

I completed my Ph.D. in physics at JILA / CU Boulder under Graeme Smith, and a research master's in quantum technology at the University of Birmingham as a Fulbright Postgraduate Scholar.

Alongside research, I am committed to teaching, mentorship, and outreach. Toward the end of my Ph.D., I co-founded the Idealized Science Institute — an educational non-profit that develops free, high-quality resources and professional development for STEM teachers. Many of my research projects involve undergraduate and master's students as co-authors.

Teaching & outreach

In the classroom

Teaching physics with care.

I believe physics education works best when students see the field as a living human practice — full of revisions, dead ends, and unfinished problems — rather than a finished set of facts. My courses combine rigorous problem-solving with the historical and conceptual context that gives the equations their meaning.

Beyond the university

The Idealized Science Institute.

I co-founded ISI to bring authentic science into K-12 classrooms — through teacher professional development, free curricular resources, and an annual regional science conference for high schoolers. The non-profit operates in-person throughout southwest Pennsylvania, but has an international presence online.
