About

I'm a CS student at Purdue (grad May 2027) and an undergraduate researcher working low in the stack: real-time DSP on FPGA/SoC, firmware, and signal processing. Right now I'm building a sub-24ms audio steganography pipeline on a Zynq-7000, and porting it to NVIDIA Jetson hardware.

Lately I've also been building software for AR glasses. On the security side I co-founded HackArmour, a search engine and CTF community, and I'm always up for more projects where embedded systems meet security.

Experience

Undergraduate Research Assistant · CYNICS Research Group, Purdue

  • Architecting a real-time audio steganography system on a Zynq-7000 SoC, replacing a batch model with a streaming pipeline that cut input-to-output latency from 5s to under 24ms.
  • Built a Direct Sequence Spread Spectrum (DSSS) “soft modem” in C to embed compressed bitstreams into carrier audio, with DMA double-buffering for glitch-free playback.
  • Wrote a bit-exact MATLAB verification suite that diagnosed Q16 fixed-point quantization, RNG desync, and ADC saturation bugs in firmware.
  • Porting the real-time streaming pipeline to NVIDIA Jetson hardware.

Undergraduate Researcher · Frederick National Laboratory (Purdue Datamine)

  • Building an LLM-powered system to harmonize biomedical vocabularies, automating ontology alignment via Neo4j semantic search.
  • Designed a Streamlit interface for researchers to batch-map terms, review alignments, and feed back corrections.
  • Engineered backend pipelines to ingest and update evolving ontologies (NCIt, caDSR, UBERON) for cancer-research data integration.
Aug 2025 – Present

Educator & Course Coordinator · LIFE Robotics

  • Designed and delivered a web-development curriculum (JS frameworks) to 20+ students, including secure-coding and web-vuln modules.
  • Mentored 3 teams (9 students) for the World Robotics Olympiad 2023; one team placed 3rd nationally.
