Dr. Claire Cramer

Claire Cramer develops novel techniques to improve the precision of astronomical spectroscopy, stellar radiometry and absolute stellar spectroradiometry using tunable lasers. Her interests include laser-based calibration and characterization of astronomical cameras and spectrographs, ground-based atmospheric monitoring for astronomy and climate science, reducing sources of systematic uncertainty in dark energy measurements, and precision laboratory tests of fundamental symmetries.
