Kyle Beloy (Fed)

Kyle Beloy is a research scientist in the Time and Frequency Division at NIST. The most accurate and precise measurements in science are underpinned by atomic clocks. Kyle's research focuses on advancing the state-of-the-art for atomic clocks, including the ytterbium optical lattice clocks at NIST. This includes developing strategies to address various effects that afflict the clocks at new levels of metrological performance.
