My name is Sixiang Zhai, a junior girl. I'm from Hunan, now studying in Polymer Materials and Engineering of Beijing Technology and Business University. I have excellent academic performances, with a GPA of 4.23. I have rich basic knowledge of materials, major in polymer chemistry, polymer physics, polymer auxiliaries and other courses, and have good analytical and self-study capabilities. Additionally, I have passed the CET-6 examination for Chinese college students, possessing excellent listening, speaking and writing skills. At present, under the leadership of Professor Hui Sun in my university, I can think independently and resourcefully in the process of learning biodegradable materials such as polylactic acid, lignin and cellulose, having a high sense of responsibility, and always be willing to learn and strive hard.
