Ms. Outcalt received her bachelor's degree in Chemical Engineering from the University of Colorado in 1987 and has been employed at NIST since graduation. She began at NIST measuring the fugacity of hydrogen in mixtures of importance to the fuel gas industry which figured into the development of equations of state for natural gas and liquefied petroleum gas. As part of this work, she was also involved with the development of analytical methods and devices for fuel gas, and was part of the development of analytical sampling and detection devices. More recently, she has advanced measurements in a number of thermophysical properties, among them solubility, vapor pressure, density and bubble point. She has led the development of standard practices in the application of vibrating tube densimetry, a field in which she is recognized worldwide as an authority.
Ms. Outcalt also worked on correlations of equations of state for some of the early alternative refrigerants. Her current areas of focus include the measurement of compressed-liquid densities of fuels and their constituents and measuring bubble points of binary mixtures as potential new refrigerants. When not working, Ms. Outcalt is an avid swimmer and cyclist.
