Exploring signals, software, and the physics of the cosmos.

I am a high school student passionate about embedded systems, signal processing, astrophysics, and open-source engineering. My primary aspiration is to explore the intersection between physics and electronics while developing accessible tools for scientific computing and radio observation.

Whether I'm analyzing spectral data, constructing custom software utilities on Linux, practicing radio telemetry, or playing classical instruments, I enjoy discovering how complex mathematical and physical systems fit together.

Investigations

Opportunistic atmospheric sensing, ionospheric sounding, and novel computing architectures!

Academic & Scientific Working Groups:
  • HamSCI HF Channel Sounding Working Group: Lead developer on wsjt-probe channel sounder.
  • HamSCI K-12 Curricular Integration Group: Contributing to the development of a curriculum for the Personal Space Weather Station (PSWS).

FT8 Opportunistic Ionospheric Sounding (wsjt-probe)

>GitHub Repo<

Invented a novel method for opportunistic atmospheric sensing using open-source amateur FT8 radio signals. Unlike traditional broad observables, this protocol reconstructs received signals to perform waveform-level comparisons directly on the receiver end, eliminating the need to store massive I/Q datasets.

In Progress: Verifying on-the-air data & collaborating with HamSCI for international PSWS deployment. C++ / Python / Signal Processing

Wireless Signal Neuromorphic Architecture (neurodft)

>GitHub Repo<

Independently conceptualized and developed a neuromorphic computing model using wireless signal properties. Demonstrates auto-associative memory with routing complexity significantly reduced compared to standard industry baselines.
