I define a technical question, build the software or experiment needed to test it, compare the result against simpler baselines and falsification controls, and document what the evidence supports—including when the answer is negative.
That process has taken me across climate forecasting, financial time series, signal processing, synthetic-aperture radar, and the built environment. The domains change; the working method is consistent: explicit assumptions, reproducible implementation, controlled evaluation, and clear technical writing.
I choose projects out of curiosity and finish them with working code, documented methods, or a clear written result.
