PhD Student in Plant Functional Traits and Process-Based Modelling
We invite applications for a full-time funded PhD position in a collaborative research project aimed at understanding hydraulic trait variation in forestry trees and incorporating these traits into a process-based model of plant function.
Project Overview
The overarching goal is to quantify key functional traits associated with plant hydraulic function in forestry genotypes. Data will be collected at an open-air forestry laboratory at the University of Pretoria, where a controlled drought experiment will take place. You will be based at Wits in Johannesburg.
Role & Responsibilities
As a PhD candidate, you will focus on:
• Quantifying hydraulic and functional traits (e.g., xylem vulnerability curves, leaf gas exchange)
• Operating sap flow and microclimate instrumentation
• Contributing to the logistics and data collection for drought experiments
• Processing and analyzing plant physiological datasets in R
• Contributing to model parameterization and hypothesis testing
Training Provided
You will receive training in:
• Plant hydraulics and gas-exchange physiology
• Sap flow measurement techniques
• Drought experiment design
• Data analysis and model parameterization
• Scientific writing and presentation
Candidate Profile
We seek applicants with a background in:
• Plant biology or plant physiology
• Ecology or environmental sciences
• Biophysics or forestry
While prior experience in plant hydraulics or IRGA/sap flow is beneficial, curiosity, perseverance, and attention to detail are more important.
As the position is based in South Africa, preference will be given to candidates from South Africa or other suitably qualified candidates who are willing to relocate
Funding & Duration
The PhD position is funded for 3 years, with a stipend in line with competitive national bursary levels.
How to Apply
To apply, email a single PDF containing your cover letter, CV, contact details for two references, and academic transcripts to Prof Rob Skelton, Prof Mary Scholes, Dr Yolandi Ernst and Dr Caroline Hardy at the following email address: caroline.hardy@wits.ac.za
Application Deadline
We will start to consider applications on 31 March 2026 and will continue to consider applications until an appointment is made.
Join our innovative research program at the University of the Witwatersrand and contribute to vital research in plant hydraulics and functional traits!
Postdoctoral Research in Plant Functional Traits and Process-Based Modelling
We invite applications for a funded Postdoctoral Researcher position in a collaborative research project focused on hydraulic trait variation in forestry trees and their integration into a process-based model of plant function.
This project is crucial in predicting the performance of forestry genotypes under changing climatic conditions.
Project Overview
The project aims to quantify key functional traits associated with plant hydraulic function in forestry genotypes. You will be based at Wits in Johannesburg, while measurements will be conducted at an open-air forestry laboratory at the University of Pretoria.
Role & Responsibilities
As a Postdoctoral Researcher, you will:
• Lead functional trait quantification and its integration with modelling
• Work with physiological datasets for calibration and validation
• Contribute to drought experiment design
• Lead manuscript preparation and publication strategy
• Co-supervise PhD students and contribute to lab development
Candidate Profile
We seek applicants with:
• Strong knowledge in Plant Physiology (primary skill)
• Experience in process-based modelling of vegetation or ecosystems (secondary skill)
• Familiarity with functional trait biology, eco-hydrology, and quantitative ecology or biophysics is advantageous
• Quantitative analysis or modelling skills (such as competence in R or Python) are beneficial
As the position is based in South Africa, preference will be given to candidates from South Africa or other suitably qualified candidates, who are willing to relocate.
Funding & Duration
The Postdoctoral position is funded for 1 year, offering a stipend commensurate with experience and available funding. Extensions for a second year may be considered based on exceptional performance.
