Biographical Narrative

Dr. Saifudeen graduated with a B.S. in Life Sciences from St. Xavier’s College, University of Bombay in 1987. After earning an M.S. in Molecular Biology from Northeastern University in Boston, MA in 1991, she moved to New Orleans and enrolled in the Interdepartmental Molecular and Cellular Biology Graduate Program at Tulane SOM. In line with her interest in transcription and cancer, and under the mentorship of Dr. Melanie Ehrlich in the Department of Biochemistry, her Ph.D. dissertation was on transcriptional regulation by methylated DNA binding proteins. Upon graduation in 1997, she started her post-doctoral training with Dr. Samir El-Dahr in Tulane's Department of Pediatrics. Her research involved transcriptional regulation of kidney development. She was appointed assistant professor in Pediatrics in 2005. During her training period, she received and was supported by an NRSA (2001-2004), followed by a National Kidney Foundation Young Investigator Grant (2005-2007) and the American Society of Nephrology Career Development Award (Carl W. Gottschalk Research Scholar) (2006-2008). From 2007-2012, she received funding as a Junior Investigator from the Hypertension COBRE (Dr. Navar, P.I.; Dr. El-Dahr, mentor). As indicated by her publications, Dr. Saifudeen's research continues to focus on kidney development, specifically on p53-regulated signaling and metabolic pathways in nephron progenitor cell self-renewal. Dissecting the function of a potent tumor-suppressor such as p53 in a normal physiological setting rather than in a pathophysiological one is of considerable clinical significance not only to renal disease but to cancer as well.
