My research interests lie primarily at the intersection of quantum algorithms and scientific computing. Prior work has consisted of algorithmic work toward the binary closest vector problem using HPCs and quantum computing (DQI), exploring QML and quantum kernels for cybersecurity applications, and using VQEs for chemical simulation. For all of these I am interested in circuit optimization and routing for NISQ computers. See more below.
Co-developed the blocked fast Walsh–Hadamard transform (BFWHT), an exact set-covering decoder for the low-weight binary closest vector problem, with CUDA/GPU implementations benchmarked on A100-class hardware. Built the end-to-end Decoded Quantum Interferometry (DQI) research codebase with interchangeable decoders and reversible resource estimation, and executed on a 156-qubit IBM QPU.
Under Dr. Brian Callahan developed augmented-reality CTF challenges in steganography, DNS poisoning, and MFA bypass; coauthored a CISSE journal article and ASIA proceedings paper on generative AI and cybersecurity pedagogy.
