The project involves design, development, and implementation of a laser-based optical sensor. The sensor will be used to monitor environmental pollutants (e.g., NOx, CO) or greenhouse gas emissions (e.g., N2O, CH4, CO2). The student will work on studying the electromagnetic spectrum of various molecules, choosing the candidate optical transitions, setting up the laser-based optical setup, and performinglaboratory measurements to detect species concentration in trace quantities. Advanced sensing strategies, such as wavelength modulation, cavity-enhancement and frequency combs will be utilized. The student will gain expertise in spectroscopy,statistical thermodynamics, machine learning, optical engineering, and mechanical design.​​​
