Katalin Susztak, M.D., Ph.D.
Dr. Katalin Susztak is a physician-scientist at the University of Pennsylvania. Her laboratory is interested in understanding the pathomechanism of chronic kidney disease development. Susztak has made discoveries fundamental towards defining critical genes, cell types and mechanisms of chronic kidney disease. She was instrumental in defining genetic, epigenetic transcriptional changes in diseased human kidneys. She identified novel kidney disease genes and demonstrated the contribution of Notch signaling and metabolic dysregulation in kidney disease development.
Her lab was the first to map the kidney epigenome and catalogue genotype-driven gene-expression variation (eQTL) in human kidneys. Integration of GWAS, eQTL and epigenome data has been essential to prioritize disease-causing genes and variants.
Dr. Susztak generated the first unbiased, comprehensive kidney cell-type atlas using single cell transcriptomics. She identified that specific renal endophenotypes are linked and likely caused by the dysfunction of specific cell types.
In follow-up animal model studies, she conclusively demonstrated that MANBA, DAB2, DACH1 and APOL1 are new kidney disease risk genes. Her work established the role of proximal tubule cells, endolysosomal trafficking, metabolic and developmental pathways in kidney disease development.
Susztak’s discoveries span genetics, genomics, epigenetics, molecular biology, physiology and nephrology, and have enormous translational relevance and considerable therapeutic potential.
Dr. Susztak has been the recipient of the 2011 Young Investigator Award of the American Society of Nephrology and American Heart Association; one of the most prestigious award given to researchers under the age of 41 in the field of nephrology. Her laboratory is supported by the National Institute of Health, the American Diabetes Association, the Juvenile Diabetes Research Foundation and private sources.
“I think this is a really exciting time in science. New technologies are emerging, which will really accelerate research progress, and I think we have fantastic new discoveries ahead of us in biology.”
