Cosmology and Fundamental Theory

Observational Astrophysics

An independent cosmology research project centered on a nonsingular bounce model in Einstein-Cartan gravity. The work studies how a steep scalar potential and spin-torsion effects can produce a bounce without a singularity, while also suppressing shear and controlling curvature in a nearly FLRW universe.
Using a six-dimensional dynamical system that extends the classic Copeland-Liddle-Wands framework, I computed the full Jacobian, analyzed Lyapunov behavior, and identified a finite bounce basin in parameter space where the model remains nonsingular and non-chaotic at the homogeneous level.

A fully functional radio telescope with azimuth and elevation control, GPS, and real-time tracking. I designed and built the wiring, control system, and software myself, with a focus on making a low-cost instrument that could still do meaningful observational work.

An interactive voice assistant built on a Raspberry Pi 5. It uses speech-to-text for input and responds through customizable text-to-speech. I built it as a practical way to interact with information more naturally while working on other tasks.

Coming soon. This project analyzes archival Chandra X-ray data to search for and characterize pulsar candidates across long time baselines.

A compact 3D scanner that uses an RPLidar and a motorized turntable to capture full 360-degree scans of small objects. As the object rotates, the lidar records distance data that can be assembled into a point cloud for reconstruction and modeling.

A collection of smaller independent builds involving electronics, microcontrollers, CAD, and 3D printing. Some are practical tools, some are experimental ideas, and some were built simply because I wanted to see if I could make them work.
