Integrative Biology includes and incorporates many approaches in studying living systems. For example, sustainable freshwater resources provide a foundation for aquatic and terrestrial ecosystems, as well as human use and economic development. However, inadequate understanding of aquatic resources and a prevailing inability to properly integrate scientific, technical, and socioeconomic elements continue to seriously hinder the goal of providing sustainable aquatic resources, not only in Texas, but also across the nation and around the world. Our doctoral program emphasizes original research and is designed to provide depth and breadth of knowledge as well as encourage an integrative approach to research. This can also include an examination of management and policy.
