Marcia L. Huber

Chemical Engineer

Dr. Huber received a B.S. in Chemical Engineering at the University of Pittsburgh, and a Ph. D. in Chemical and Petroleum Refining Engineering at the Colorado School of Mines after a brief stint working for Rockwell International. She came to NIST as an NRC postdoctoral researcher working with Dr. Jim Ely, focusing on developing extended corresponding states models for the properties of fluids, especially heavy hydrocarbons. This work was expanded and incorporated into several early computer databases for thermophysical properties, including what is now NIST Database 23, more commonly called REFPROP. She was Group Leader of the Theory and Modelling of Fluids Group for several years, and is very active in organizing the International Symposium on Thermophysical Properties, held triennially in Boulder. When she isn’t working, her interests include trail running, hiking in the mountains, wildflower photography, lifting heavy things, enjoying the company of her dog, family, and friends, and drinking lots of coffee.

Research Interests:

Modeling the Thermophysical Properties of Fluids
Dr. Huber is interested in many aspects of developing models for the thermophysical properties of fluids. She often is involved with international collaborations to develop reference fluid correlations for the viscosity and thermal conductivity of many industrially important pure fluids such as carbon dioxide  and water. Most recently she has focused on proposed low-GWP replacement refrigerants such as R1234yf and R1233zd(E). She also is interested in developing surrogate mixture models for the thermodynamic and transport properties of complex fuel mixtures, including aviation and transport fuels. Recent work has focused on low-sulfur diesel fuels, past research included biofuels, rocket propellants, and aviation fuels.  Much of this work has been done in collaboration with Dr. Tom Bruno, also of NIST. Other interests include the solid-liquid boundary of fluids, fire-suppressant mixtures, surface tension, and development of mixture models for thermophysical properties. She also is part of the team that continuously works on developing and improving the REFPROP program.
