Daniel W. Lozier (b. 1941 in Portland, Oregon) is Group Leader of the Mathematical Software Group in the Mathematical and Computational Sciences Division of NIST. He is also the General Editor for the DLMF project.
Lozier received a degree in mathematics from Oregon State University in 1962 and his Ph.D. in applied mathematics from the University of Maryland, College Park, in 1979. In 1963–1969 he worked at the U. S. Army Engineer Research and Development Laboratory in Virginia on finite-difference solutions of differential equations associated with nuclear weapons effects. Then he transferred to NIST (then known as the National Bureau of Standards), where he collaborated for several years with the Building and Fire Research Laboratory developing and applying finite-difference and spectral methods to differential equation models of fire growth. His research interests have centered on numerical analysis, special functions, computer arithmetic, and mathematical software construction and testing.
Lozier has been a frequent speaker at conferences, and has published numerous papers in journals and conference proceedings. He has served as an associate editor of Mathematics of Computation and of the NIST Journal of Research. He has also served several terms as an officer of the SIAM Activity Group on Orthogonal Polynomials and Special Functions. In 2008 he was named an Honorary Fellow of the European Society of Computational Methods in Sciences and Engineering.
