Salaam! "My name is Saeid Gharaati, and I graduated from Azad University of Isfahan in (year?) with a B.Sc and M.Sc in food science and engineering. I defended my thesis in September 2014. (Maybe talk a little more about your thesis? It is a random sentence that seems to need explanations) I have been teaching in Fadak Technical and Vocational University since 2012, and I have worked with other universities including Iranian Food and Drug Organization in Kashan University of Medical Sciences in order to improve food quality since 2015. Furthermore, I participated in several meetings of Iranian National Standards Organization for standardization of food industries and had about 660 hours of training related to my field of study. I have a strong interest and ambition to further advance my bandwidth in my field, thus I wish to begin pursuing my studies by working on a PhD degree. (Tips and suggestions: Avoid using contractions in formal papers; you used a lot of "I've" and "I'm." very informal. Also, try adding some variety in your sentences, so avoid starting each sentence with "I've..." "I've...." ..it shows lack of strong language use, and in Ph.D studies you will be required to write a lot, so it is a skill they will analyze. So, you can fix this by adding variety through using words such as furthermore/in addition/Also, etc. Also, never start sentences with "And...". Overall, good job! Good luck! )
