Ahmed El-Shafei, an Associate Professor in the Polymer and Color Chemistry Program at North Carolina State University, joined the faculty in 2008 after 5-year of conducting research as a Research Assistant Professor at NC State in different chemistry areas with a focus towards functional dyes including dye-sensitized solar cells, photodynamic therapy, and understanding photostability, photophysics and photodegradation mechanisms of dyes and polymers. He received a B.S. (1989) with honors and a M.Sc. (1994) in Organic Chemistry both from Mansoura University, Egypt, and a Co-Major Ph.D. (2002) in Chemistry and Fiber and Polymer Science from North Carolina State University. El-Shafei’s current research interests span molecular engineering, molecular modeling (DFT/TD-DFT), synthesis, photophysics, electrochemistry and photovoltaic properties of dyes for dyes-sensitized solar cells and PDT. The second research area of interest in El-Shafei’s group focuses on the synthesis and nanolayer graft polymerization of different monomer functionalities for different end uses including woven, nonwovens, and knitted fabrics for fuel filtrations, medical applications and flame retardancy. Another research thrust of El-Shafei is on molecular modeling and synthesis of thermochromic and photochromic dyes, and dyes for ink-jet printing.
