Serhat Karadağ, MD, Associate Professor of Nephrology, is a clinical nephrologist and academic physician based in Istanbul, Türkiye. His research focuses on chronic kidney disease (CKD), acute kidney injury (AKI), and outcome-oriented nephrology research, with emphasis on risk stratification, long-term renal prognosis, and multicenter cohort analyses. He has contributed to national registry-based studies evaluating renal outcomes in infectious diseases, including COVID-19–associated kidney involvement and post-infectious renal sequelae. Assoc. Prof. Karadağ has a particular academic focus on glomerular diseases, including immune-mediated nephropathies and biopsy-proven primary glomerulonephritis. His research examines the diagnostic and prognostic value of inflammatory, immunologic, and hematologic biomarkers in kidney disease progression. He is especially interested in translational approaches involving serological markers in membranous nephropathy and ANCA-associated vasculitis, with attention to disease activity assessment and outcome prediction. His additional research interests include diabetic kidney disease, cardiorenal interactions, dialysis outcomes, and the implementation of evidence-based international guidelines into clinical nephrology practice.
