Short Professional Biography

Dr. Florastina Payton-Stewart received a B.S. degree in Chemistry from Xavier University of Louisiana in 1999 and her PhD in Bioorganic Chemistry at Tulane University in 2007.  After receiving her Ph.D., Dr. Payton-Stewart held a postdoctoral position at Tulane University Medical School from 2007-2010.  She is the recipient of various honors, such as the Cancer Association of Greater New Orleans Fellowship, the GALA Dissertation Writing Fellowship, the Louisiana Cancer Research Consortium Fellowship and the Susan G. Komen Postdoctoral Fellowship.  She has mentored and trained several undergraduate students on projects related to the biological activity of natural phytoalexins. She joined the Chemistry department faculty at Xavier University in August 2010.

 

Research Interest

Dr. Payton-Stewart’s research focuses on identifying novel endocrine therapeutics by incorporating two discrete disciplines, synthetic chemistry and molecular biology.  This project involves the design, synthesis, characterization, and biological screening of novel anti-cancer agents.  The research further involves understanding the molecular mechanism and biological activity of naturally occurring plant phytoalexins and their analogs as they pertain to breast carcinomas.
