Esther Baumann is a research scientist at NIST and has worked for 16 years in designing and building fiber frequency combs and exploring innovative laser and frequency comb applications. She is passionate about establishing synergies through cross-disciplinary collaboration, with her work touching diverse fields from laser ranging through fire to muscle health assessment. Baumann has been actively engaged in high-precision, molecular dual-comb spectroscopy of gas phases, including monitoring greenhouse gases. Recently, Baumann shifted her concentration toward the free-form dual-comb platform. This new and improved dual-comb spectrometer, created by her team, is designed to intelligently gather the most pertinent parts of a signal during measurement, making it a more adaptable and versatile tool.
