The Resh Lab is part of the Department of Environmental Science, Policy, and Management, Division of Organisms & Environment at the University of California, Berkeley.

The research program in the Resh laboratory follows three lines: (1) studies of the evolutionary biology and ecology of aquatic insects, crustaceans, and molluscs in stream and river habitats; (2) the evaluation of habitat manipulations for use in environmental restoration or enhancement, and the use of them in examining underlying influences of ecological interactions; and (3) the development of techniques for the biological assessment of water quality.
