The Applied and Computational Mathematics Division (ACMD) of the National Institute of Standards and Technology (NIST) anticipates an opening for an engineering scientist, theoretical physicist, or applied mathematician. A successful candidate will (a) engage in research in mathematics of metrology, with emphasis on mathematical modeling of physical, chemical, and/or biological systems being studied at NIST, as well as for fundamental metrology, (b) work closely with scientists at NIST and elsewhere to design and analyze the results of corresponding experiments and instrument performance, (c) work with external groups to establish benchmarks for biometrology, (d) disseminate results through research articles and technical presentations, and (e) provide technical guidance to postdocs and
