I look closer.

A personal record of what I build, what I learn, and the questions that stay with me.

A working archive
for unfinished ideas

Why this website exists

This is where I document what I build, what I learn, and what I think about.

Part engineering notebook, part editorial journal. A place to make ideas clearer by putting them into words.

02 / Selected practice

Selected Work

A selection of projects, experiments, and research across physical systems and computation.

NH₃ H₂ N₂ Combustion
Reduced Order Model

Machine learning / Combustion / CFD

A physics-guided reduced-order model combining adiabatic CFD, conjugate heat-transfer simulation, finite-rate Cantera/Otomo chemistry, and experimental residual machine learning to predict burner temperature, NO, and product composition.

About me

I’m interested in the intersection of engineering, computation, science, and the process of learning itself.

This website is where those interests meet.
