The Leaf Lab conducts patient-oriented research in acute kidney injury (AKI) and critical illness. Our goal is to develop novel approaches to prevent AKI, and to improve outcomes in patients who suffer from AKI. Read more about AKI.
Our research is highly collaborative and interdisciplinary and includes:
• Randomized trials
• Biomarker studies
• Genetics
• Epidemiology
