My name is Saeed Kosari and I am writing to apply for research position in your esteemed research group. I have done PhD (mathematics) from 2012 (IRAN), and now I am going to complete post-doctorate degree from Guangzhou university.    I would like to briefly mention that in PhD I have exclusively worked on domination in graph and have published several papers in peer-reviewed journals such as Filomat etc. Overall, I have published 29 research articles in international journals. It will be a matter of great honor for me if you could give me an opportunity to work with you. I am sending you my CV, and if you need any other information, I will be happy to provide.  Hope to hear from you soon. Thanks for your time.   Best wishes,   S. Kosari
