Stephan Schlamminger is a physicist in the Quantum Measurement Division at NIST. He has worked on obtaining precise determinations of the Planck constant and the gravitational constant. Currently, his research interest is in the measurement of small masses based on a fixed value of the Planck constant. He is still trying to figure out what the precise value of the gravitational constant is. He likes all coffee-related things, without being a snob about it.
