01 / Research

At the intersection of combustion particles and material science.

Featured project · PhD research

Tracing a world-first particle phenomenon

I identified ammonium nitrate nanoparticle emissions in ammonia-fueled engines and combustors, then connected their size, morphology, and chemistry to operating conditions and formation pathways.

05 / About

Experimentalist driven by curiosity, analytical thinking, and measurable results.

I'm a mechanical engineer and experimental researcher at the University of Minnesota. My work is grounded in careful measurement, practical design, and the belief that complex systems become tractable when we connect observations across scales.

Beyond my own experiments, I mentored new researchers in laboratory practice, instrument operation, publication, conference opportunities, and a strong culture of safety.
