Dr. Orzechowska's research emphasis is in atmospheric sciences, environmental chemistry, analytical chemistry, and radiochemistry. Her specific interests are in the planetary chemistry of solar icy moons - chemical and physical processes occurring in water ice matrix at low temperatures (50-100 K) and pressures of 10^-7 Torr; studies of oxidation processes in the atmosphere - reactions of ozone and OH radicals with alkenes, and; study of the conversion chemistry of cocaine and heroin - participation in development of a hand held-field portable gas chromatograph and a surface acoustic wave detector. Her skills include wet chemistry with many instrumental techniques: GC/FID, GC/MS, HPLC/MS, IMS, AAS, UV/VIS spectrometry, alpha, beta, and gamma spectroscopy.
