I present a summary of recent scientific projects relevant to the areas being discussed at this conference that have been or are in the process of being carried out at the Keck telescope by astronomers from the California Institute of Technology. Note that in most cases these are team projects, and many people are involved. Among the highlights thus far in the area of gravitational lensing are the detection of an emission line in the lens B0218+357 implying, if its identification as Mgll is correct, a redshift of 0.95, and the detection of a redshift of 0.53 for one of the arcs in the X-ray emitting cluster of galaxies MS 0440+0204. Highlights in the area of distant galaxies include the deepest published optical and infrared counts, reaching to K = 24.5 mag and to R ≈ 27 mag. The first results from a redshift survey of faint field galaxies which will eventually reach to K ≤ 20 mag are also shown.
