Hardware & 3D Printing
3D-printed spectroelectrochemical cells
Custom PETG battery cells, designed so a Raman laser can look inside while they run, printed and iterated in-house on a Bambu Lab X2D.

I watch batteries while they work.
I point lasers into rechargeable zinc batteries to see what happens at the electrode as they charge and discharge. I design and 3D-print the cells that make that possible, and I’m working with machine-learning researchers on models that could help choose which experiment to run next.
Watching a zinc battery while it works
Most battery tests treat the cell as a black box: charge in, charge out, count what comes back. That tells you a battery is wearing out, not why. Raman spectroscopy reads the chemistry at the electrode surface as it happens, so a change in behavior can be traced to a change in molecules.
Methods: operando Raman spectroscopy, SHINERS, custom 3D-printed cells, Python analysis.
How it works →Teaching a model to pick my next experiment
Benchmarking simple and complex machine-learning models on my experimental data, then using active learning so the model helps choose which experiment to run next.In progress. Comparing ridge regression, random forests and neural networks; active learning is next.ML & Pipelines
Spectral analysis in Python
The Python code that turns thousands of raw operando spectra into something a person, or a model, can reason about.
Software & Games
Card and board game collection for iOS
A collection of card and board games for iPhone, built in Swift and SwiftUI.
- Benchmarking ridge regression, random forests and neural networks on my experimental data with Yuxin Chen’s group, with active learning next.
- Learning ML pipeline engineering and lab automation, in public.
- Writing up my thesis research. PhD expected June 2027.
