The Department of Integrative Biology is home to 38 faculty members with interests in diverse areas of biology, ranging from the smallest scale of individual genes or proteins to individual organisms, populations, and entire ecosystems. Members of the Department study animals, plants, and microbes, and they carry out highly interdisciplinary research aimed at developing an integrative perspective of life on earth. Research interests of the individual faculty members are provided on the faculty web pages.

The Department of Integrative Biology is housed primarily in two buildings: Patterson Labs (PAT) and Biological Laboratories (BIO). Faculty laboratories in these buildings include state of the art facilities for performing organismal, molecular, and computational research. A number of Organized Research Units are associated with the department, such as the Center for Brain, Behavior, and Evolution.

Within its world-class Biodiversity Center, the Department also houses a large and diverse collection of museum specimens for use by faculty and students in its Biodiversity Collections, which includes an expansive plant resource center, and opportunities for performing field studies close to the UT campus at the Brackenridge Field Laboratory and its satellite, Stengl Lost Pines Biological Research Station.
