Keegan Orr studies low-temperature and high-pressure plasmas using laser-based optical diagnostics, focusing on how energy is stored and released in molecules like oxygen and nitrogen during electrical discharges. This work uses techniques such as Raman scattering, second-harmonic generation, and vibrational spectroscopy to measure electric fields, temperature, and molecular excitation in plasma jets and discharge reactors, with applications relevant to combustion, aerospace, and energy systems. The listed research area of 'Medicine' does not match the publication record, which is centered on plasma physics and applied spectroscopy.
Publication output has been fairly steady at 2-5 papers per year for most of the last decade, with a dip to zero in 2025 followed by an increase in 2026.
