A PhD Position in Stream Ecology at University of Texas at Arlington, Texas

Expiration Date: 

A PhD position to study the ecology of stream communities under global change is available in Dr. Sophia Passy’s laboratory at the University of Texas at Arlington ( The start date will correspond with the start of the Spring 2022 semester. The successful applicant is expected to have expertise in ecology, experience with statistical data analysis, and excellent communication skills. Having a master’s degree in ecology or environmental sciences is preferred. 

Using experimental data and extensive national and international databases of freshwater organisms (algae, macroinvertebrates, and fish), the student will contribute to a new interdisciplinary endeavor merging stream ecology, network science, and global change. The goal of this research is to determine how biodiversity and species co-occurrence networks in streams—one of the most threatened ecosystems on Earth—would respond to increasing nutrient concentrations and climate change under mitigated, stabilizing, and increasing greenhouse gas emissions. The outcomes would have the potential to influence environmental policy and stream management. The project will involve close collaboration with a diverse group of students, postdocs, and scientists from the US, France, Finland, and China. Additionally, the student will actively participate in the UT Arlington Stream Team, a group of students and members of the public, performing citizen science projects on water quality issues in Texas. The student will acquire highly marketable skills, including big data analysis, development and implementation of cutting-edge statistical techniques, leading international collaborations, and organizing citizen science efforts.  

To apply, please e-mail by September 15, 2021, your CV, a statement of research interests, GRE scores, TOEFL scores for international students, and the names and contact information of three references to Dr. Sophia Passy (
