Wysocki conducts research that is primarily focused on the development of mid-infrared laser spectroscopic instrumentation for applications in trace-gas detection and chemical sensing. The target applications range from atmospheric chemistry, environmental detection and bio-medical research, to industrial emission monitoring and process control.
His current research interests include development of new tunable mid-infrared lasers and their applications to multi-species molecular detection, studies of new molecular dispersion sensing techniques for in-situ and remote chemical analysis and quantification, mid-infrared radiometry for passive atmospheric sounding and development of distributed laser-spectroscopic sensor networks for real-time, large-area, in-situ trace-gas monitoring and pollution mapping.
