A quiet research notebook on complex systems, nonlinear dynamics, and the habits of experimental and computational work.

About

I'm a second-year physics student building toward research in complex systems and nonlinear dynamics. This site is a public notebook of experiments, simulations, and ideas in progress.

I care about how simple rules generate structure across scales: nonlinear dynamics, emergence, and the geometry behind physical systems. I learn by building models, running measurements, and writing down what fails as much as what works.

I'm looking for research environments that value careful thinking, honest uncertainty, and iterative work with mentorship.

Coursework

Experimental Work

Raman spectrum of carbon allotropes

Raman Spectroscopy

Characterised carbon allotropes via D/G band ratios, estimated graphene layer count, and identified an unknown semiconductor wafer from its 521 cm⁻¹ mode.

Paschen curve with Townsend theory

Paschen Curve & Gas Discharge

Mapped breakdown voltage vs. electrode gap at three pressures; extracted the second Townsend coefficient and identified the avalanche-to-streamer transition.

Fluorescence emission spectra of BSA and lysozyme

Fluorescence Spectroscopy: Protein Unfolding

Tracked acid denaturation of BSA and lysozyme via intrinsic Trp/Tyr fluorescence; observed emission shifts and intensity changes tied to tertiary structure loss.

Circular dichroism spectra

Circular Dichroism: Protein Secondary Structure

Monitored α-helical content of BSA and lysozyme under acid denaturation using far-UV CD; lysozyme's disulfide bonds preserved its secondary structure.
