In 1990 he became a Senior Engineer at Simulation Sciences Inc. (now part of Aveva) in Brea, California. After four years at Simulation Sciences, Allan went back to NIST as a Chemical Engineer working in Boulder, Colorado, where his work focuses on modeling the thermophysical properties of industrially important fluids (including "steam tables") and fluids that are important for metrology.

Allan has received multiple awards including the NIST Measurement Services Award in 1996, the Department of Commerce Bronze Medal in 2011, Fellow of ASME in 2013, and Honorary Fellow of the International Association for the Properties of Water and Steam in 2016. Allan is the Editor of the Journal of Physical and Chemical Reference Data, and he is also on the Editorial Board for the International Journal of Thermophysics.

Allan and his wife reside in Boulder, Colorado.
