About Me

Physics is built around continuous dynamics: fields evolve, operators govern their behavior, and symmetries and conservation laws constrain what can happen. Text, by contrast, is naturally represented as discrete sequences, which has shaped many of the building blocks behind modern AI. I'm interested in exploring what a different set of primitives could look like for physics, using neural operators and mathematical tools from theoretical physics to develop representations better suited to the physical world.

Previously, I was an undergrad at UMass Amherst advised by Professor Chen Wang in the Superconducting Qubit Lab on autonomous bosonic quantum error correction, and by Professor Don Towsley in the ACQuIRe Lab within the NSF Center for Quantum Networks on quantum repeater architectures and error correction for satellite links.

Quantum memories are essential components in applications ranging from quantum computing to quantum communication networks. However, their practical utility is constrained by short decoherence times, motivating the search for new physical systems that can inherently protect stored information. Discrete time crystals (DTCs)—periodically driven many-body systems exhibiting stable subharmonic oscillations that break discrete time-translation symmetry—offer a promising approach, as they are theoretically able to shield encoded information from local perturbations, making them compelling candidates for next-generation, passively protected quantum memories.

Named a 21st Century Leader

At commencement I was named one of 11 21st Century Leaders, UMass Amherst's most prestigious graduation honor. I'm grateful for the recognition, and for the people who made the years behind it possible.

Tunable Bandpass Filter Used on a PReSPA Four-Wave Mixing Drive

After eight months from idea to fab, my tunable bandpass filter ended up on one of the four-wave mixing drive lines for Passive Quantum Error Correction of Photon Loss at Breakeven, published in Physical Review X. The filter is highly stable across a continuous 12.2–16.3 GHz range, about 4 GHz of tuning over ~5 mm of element travel, and is centered on the 12.58 GHz PReSPA target. The design is modular, so parts swap cleanly, and the same architecture can be fabricated for different frequency ranges.

Joining the Superconducting Qubit Lab

I've officially joined the Superconducting Qubit Lab—home of the Schrödinger-cat qubit—where I'll be diving deep into superconducting-circuit devices for quantum information processing, including reservoir engineering, bosonic error-correction codes, and tunable band-pass filters.
