Project Description

Project Overview

This PhD project will focus on aquatic environmental science by investigating water quality and ecosystem processes in large lake systems. The research will emphasize hypoxia, biogeochemical cycling, and the effects of environmental change on lake ecosystems.

What You Will Do

The student will conduct fieldwork and laboratory experiments to collect and analyze data related to lake water quality and ecosystem dynamics. This includes studying hypoxia development, examining biogeochemical cycles, and evaluating environmental stressors. Programming skills, e.g., R, may be used for data analysis.

Expected Outcomes

The research aims to produce new insights into the mechanisms controlling water quality and ecosystem health in large lakes, contributing to better environmental management and policy development regarding aquatic resources.

Why This Matters

Understanding how hypoxia and biogeochemical processes respond to environmental change in lake systems is vital for preserving aquatic biodiversity, ensuring water quality, and maintaining ecosystem services that support communities and wildlife.

Entry Requirements

Applicants should hold a Bachelor’s or Master’s degree in environmental science, geology, chemistry, biology, or related fields. Strong interest in fieldwork, lab work, and data analysis is essential. Programming experience (e.g., R) desirable but not required.
