Dear community,

I am looking for a postdoc in my group to model biophysical interactions between vegetation and hydrodynamics in deltas. Please find more detail below.

The primary focus of the positions will be on computational modeling of grid size effects on channel-island connectivity and vegetation establishment. The project will involve coupling
dynamic vegetation and ANUGA to assess vegetation effects on island inundation in deltas for varying grid sizes. This project is part of a collaboration between researchers at LSU and ETH
Zürich.

Qualifications:
PhD in Civil Engineering, Environmental Engineering, Geophysics, Coastal Sciences, or a related field. 
Strong background in hydrodynamic processes and/or geospatial analysis.
Experience with geospatial or numerical modeling tools (e.g., ANUGA, ArcGIS, etc.).
Proficiency in Python, MATLAB, or similar programming languages for data processing and model development.
Familiarity with coastal biophysical processes is highly desirable.
Strong analytical skills and the ability to work in a team  and independently.

Start Date: November 2025


Job Responsibilities:
Conduct research in coastal processes by modeling biophysical and ecological processes in deltas using 2-D computational models; the incumbent will develop a computationally efficient coupling approach to design model validation scenarios with data, and to assess ecosystem engineering effects on vegetation establishment in a fast-growing delta in Louisiana. - 60%

Use software development and maintenance of open-source modeling software for https://github.com/murielbruckner/Dynamic-saltmarsh-microphytobenthos-model. - 20%

Mentor graduate and undergraduate students, supporting research group meetings, guiding student projects, and presenting occasional seminars and classroom presentations. - 15%

Other duties as assigned. - 5%
This position is critical to the department as the incumbent is to make fundamental contributions to the next generation of eco-hydrodynamic modeling software used to study biophysical feedbacks in deltas. The incumbent will be a member of the Department of Civil & Environmental Engineering and the interdisciplinary Center for Computation and Technology (CCT).
