David Meyer's research specialty is applying high signal-to-noise spectroscopy to the study of cosmology, galactic evolution, and the interstellar medium (ISM).  Using satellite observatories such as the Hubble Space Telescope (HST) and the Far-Ultraviolet Spectroscopic Explorer (FUSE), as well as the telescopes at ground-based facilties such as the Kitt Peak National Observatory (KPNO), Meyer is conducting sensitive measurements of the interstellar and extragalactic absorption lines in the spectra of stars and quasars.  Such measurements provide important information about the composition, chemistry, kinematics, and physical conditions of intervening gas clouds in the Milky Way and other galaxies.

In particular, Meyer is studying the abundance homogeneity for a variety of elements in the interstellar medium.  This work has revealed a remarkably homogeneous subsolar abundance of krypton in the local ISM and evidence of enhanced oxygen depletion into dust grains in denser interstellar clouds.  Through HST, FUSE, and KPNO observations of interstellar absorption lines toward high-velocity stars, binary stars, open star clusters, globular star clusters, and galaxies, Meyer is also investigating the physical conditions and geometries of small-scale structures in a wide variety of diffuse clouds.  The most recent results suggest that the small-scale structure observed in trace neutrals such as Na I may reflect the biased formation of these species in turbulence-driven density peaks in diffuse clouds.
