Hi everyone, this is my first time logging in to the Italki website. My name is Gaohang. I'm graduating from the College of Life Science at Northwestern University, with a major in cell biology. I found a job that requires me to speak English well, but right now my spoken English is poor and I don't talk with people in English. I came here to find someone who can help me improve my spoken English. I am fluent in Mandarin, so I can help others improve their Mandarin Chinese.
