Curriculum Vitae
The author of this PhD thesis was born in Ismailia, Egypt in 1969. She graduated from the General Secondary school of Abu Suwair in the same city in May 1986 and after that, she started her university education at Suez Canal University, Ismailia, Egypt. In May 1990, she graduated from the Faculty of Science and received her Bachelor degree of Science in Zoology with Excellent-Honor Grade (85 %). In the same year, 1990, she was offered a position of Demonstrator at the Department of Zoology in the same University to participate in the teaching responsibilities and to do her postgraduate studies. In May 1992, she completed within one academic year the courses required for the Master degree. She got her Master degree of Science in Zoology in 1997 “with distinction” after a scientific study on mice aiming at the evaluation of mutagenic risk of exposure to nicotine and the anti-schistosomal drug (praziquantel) as well as the synergistic effect of these chemicals. In 1998, she continued the work as assistant lecturer while preparing to study the PhD. In 1999, she was granted two years scholarship from the Egyptian government to do the experimental work of the PhD in The Netherlands. She arrived at Leiden University Medical Center in December 1999 to start her work at the Department of Toxicogenetics under supervision of Prof. Dr. A.T. Natarajan and Prof. Dr. Leon Mullenders. In 2002 she was admitted to complete the PhD in the Netherlands. During her PhD period her scientific research has mainly focused on chromatin organization of human cells exposed to genotoxic stress. Finally, after obtaining her PhD, she will be working as a lecturer postdoc at the Department of Zoology, Faculty of Science, Suez Canal University, Ismailia, Egypt.
