Nephrology Faculty Research Interests
Understanding molecular mechanisms of diabetic kidney disease.
Strives to elucidate the molecular mechanisms underlying human diseases and thereby identify useful biomarkers and druggable targets in a broad range of malignancies.

The pathophysiology of the accelerated vascular calcification and mortality in patients with chronic kidney disease (CKD) and studying potential therapies including use of specific anti-cytokine agents. Measurement of the extra-osseous calcium burden in patients with chronic kidney disease. Pathophysiology of the dyslipidemia in patients with CKD.
George A. Kaysen, M.D., Ph.D.
Human studies exploring the relationship between nutrition as measured by the level of serum albumin, prealbumin (transthyretin) transferrin, and body composition, inflammation and cardiovascular and overall outcomes and mortality in dialysis patients. I am responsible for creating a biorepository for the USRDS Nutrition special study and for measuring a number of biomarkers from samples obtained in order to relate them to body composition and clinical outcomes. My research also focuses on lipoprotein levels, structure and function as it pertains to renal disease both in humans and in experimental animal models. These have been focuses of my research for over 20 years.
Animal studies have involved the relationship between urinary protein loss and plasma protein and lipoprotein composition. My research has resulted in approximately 200 peer reviewed publications.
