## Documents
|
||
These are probably what you're looking for. A summary of the key points follows below!
|
||
|
||
- **[Curriculum Vitae (PDF)](/cv.pdf)**
|
||
- **[Resume (PDF)](/resume.pdf)**
|
||
|
||
## Education
|
||
|
||
- **Technical University of Denmark (DTU)** — MSc in Computer Science and Engineering. September 2026 – expected 2028. Expecting PhD studies after.
|
||
- **Brown University** — Sc.B. in Computer Science and Mathematics. August 2022 – May 2026
|
||
- **DIS Copenhagen / Københavns Universitet** — Semester abroad. Fall 2024
|
||
|
||
## Research Interests
|
||
|
||
My work clusters into three threads:
|
||
|
||
- **Machine learning** — order-invariant ICD-10-CM embeddings (under review at *JAMIA*, deployed calculator), the NeuroPose 3D-kinematics system in Liqi Shu's lab at Brown Neurology, and ongoing research engineering at [NeuroAI](https://neuroai.health). Undergraduate work has been clinically focused; graduate study broadens the scope.
|
||
- **Computer systems and high-performance computing** — the Weenix kernel, a TCP/IP networking stack from scratch in Go, and micro-architectural performance work (SIMD, hardware counters via PAPI, RAPL energy, cross-ISA ports across AVX2 / ARM NEON-SVE / RISC-V V) on Brown's OSCAR HPC cluster.
|
||
- **AI safety and applied AI** — zero-knowledge proofs for cryptographic verification of large language models, as a MARS V fellow with the [Cambridge AI Safety Hub](https://caish.org/mars) (mentored by James Petrie, Future of Life Institute); a Magic: The Gathering reinforcement-learning project on OSCAR; agentic-systems work at xAI on `grok-code-fast-1`; and reasoning, evaluation, and red-teaming contracts with Anthropic, Mistral, and OpenAI.
|
||
|
||
Computer vision and security thread through all three but do not stand on their own.

## Selected Projects
|
||
|
||
- **[Weenix](/essays/weenix/)** — Unix-like kernel in ~7,000 lines of C: virtual memory, VFS, system calls, threading, device drivers, interrupt handlers, and file systems. Custom linker support for running userspace x86-64 ELF binaries; extended with pipes and userspace preemption.
|
||
- **[Networking Stack from Scratch](/essays/networking-stack/)** — TCP/IP, RIP, UDP, and DNS in Go, supporting file transmission of up to 1 GB across 8-node networks. Extended with a fully RFC-compliant SSH implementation (2,000+ additional lines) supporting sustained sessions of arbitrary length.
|
||
- **[SIMD / PQC Performance Study](/essays/where-does-simd-help-post-quantum-cryptography/)** — Hand-written AVX2 assembly for ML-KEM / Kyber. 35×–56× speedup over compiler-optimized C for core NTT arithmetic; 5.4×–7.1× end-to-end KEM speedup, with a full statistical-analysis pipeline on Brown's OSCAR cluster.
