I was born in the city of Fowa in Kafr Al-Sheikh Governorate on January 1, 1984, and I received my bachelor degree in 2004 with a very good grade with honors degree (Pesticides). I was appointed as a demonstrator at the College of Agriculture in Kafr el-Sheik, Tanta University in 2005. I obtained a master's degree in agricultural sciences in 2010 (Pesticides Chemistry and Toxicology) entitled Toxicological study of some used pesticides and their residues removal in aquatic media. I received my doctorate in agricultural science philosophy in 2016 (Pesticides Chemistry and Toxicology) entitled Study the use of nanotechnology and biotechnology for the remediation of certain pesticide residues in aqueous media. Dr Moustafa Samir SaadAllah, Lecturer of Pesticide Chemistry and Toxicology, Faculty of Agriculture, Kafrelsheikh University, Egypt. Fields of study since I was a demonstrator were determination of pesticide residues in the environment, the toxic effects of pesticides on animal experiment and remediation technology of pesticide residues in water.
