مختصر السيرة الذاتية
Ayman El-Faham received his B.Sc. degree in Chemistry in 1980 and M.Sc. in 1985 in Physical Organic Chemistry, from Faculty of Science, University of Alexandria, Egypt. In 1991 he received his Ph.D degree in organic chemistry as a joint project between the University of Alexandria and the University of Massachusetts, Amherst, MA, U. S. A. under the supervision of Prof. L. A. Carpino, where he worked on the synthesis of new protecting groups for both solution and solid phase peptide synthesis. In addition I involved in the development of new coupling reagents based on 1-hydroxy-7-azabenzotriazole. I continued working on these new coupling reagents during my postdoctoral work (1992-1999) at the University of Massachusetts in Prof. Carpino’s Lab. I shared many patents in this field. In 1999 he received the University of Alexandria award in Chemistry. Also he has collaborated with Barcelona Science Park during the summer of 2006, 2007, 2008, 2009 and 2011 worked with Prof. Fernando Albericio in the development of a new family of immonium/uronium type coupling reagents. In 2000-2004, he worked as the Head of the Chemistry Department, Beriut Arab University, Lebanon. In 2004-2008 he worked as the Direct Manager of both the NMR Lab and the Central Lab at the Faculty of Science, Alexandria University, Egypt. 2008-2010, he worked at King Saud University, as a Professor of Organic Chemistry, College of Science, Chemistry Department, Saudi Arabia. In 2010, he received the D.Sc. degree in Peptide Synthesis. In 2010 he received the University of Alexandria a Medal award in Chemistry for scientific publication. 2010-2011, he worked as a Vice Dean of Community Service and Environment Development, Curently; I am Professor of Organic and Peptide Chemistry, Faculty of Science, Alexandria University, Egypt. In 2012 he received Award of Excellence in Scientific Publishing from Quality Authority (CIQAP) Egypt 2012. In 2016 he received the Unilever award for the best article.
