Biological phenomena occur at various levels of structural organization, ranging from molecules to organisms, and from populations to the global ecosystem. Integrative Biology takes a whole-organism approach, extending from the genome and proteome through organismal traits (phenotypes), to communities and ecosystems. Through the coordinated study of multiple levels of biological organization over a broad range of spatial and temporal scales, Integrative Biology offers a unique approach to understanding fundamental questions concerning the evolution and maintenance of biological diversity, including organismal form and function, and ecological and ecosystem processes. This multidimensional approach underpins our graduate program, where students combine observational, experimental, and comparative approaches with the development of theory; and apply concepts and techniques from the biological sciences and other disciplines.

Integrative Biology admits students to the PhD program only.

The Department of Integrative Biology at Berkeley explores life at all levels and our scientific community pursues research across three main areas:

  • Tree of Life: Biodiversity and Global Change

  • The Tangled Bank: Species Interactions & Biological Communities

  • Human Connections: Origins, Health and Quality of Life
