  • Experience with data analysis and programming in MATLAB/Python.
  • Familiarity with mid-infrared light (wavelengths above the communication band).
  • Familiarity with infrared spectroscopy and its applications and analysis of absorption spectra.
  • Familiarity with nonlinear optics, especially second-order nonlinear effects.


The salary and benefits for this position are negotiable and will be discussed during the hiring process.
