Diary
I came to Perth in 21st of March at noon. Two French guys invited/welcomed me on the airport. My first feeling/impression of Perth was that it's warm and peaceful. Really  Many things have actually been happened during the first two weeks/ couple of weeks. Unforgettable  On the first day, I unforgettably met David Reckhow, a professor in Univ. of Mass in the US. I recently read some of his papers recently, and he suddenly/abruptly came up to me. And Suddenly, Sebastien suggest=suggested me to have discussion with him. It was quite stressful at the=that moment, but the effort to preparation of=in preparing for the meeting and discussion with him was really valuable.
For the last two weeks, I have tried to be accustomed with the laboratory and office environment. Sometimes, I felt=feel stressful because I’m not familiar with the laboratory processes here. Specifically, when I’m looking for something (e.g., vials, magnetic bars, etc.), I still need to ask help from other labmates. I felt very sorry to bother them. However, all of my lab members are very kind and they don’t hesitate to help me. Thus, I’m becoming very familiar/comfortable with this environment. I’m happy now 
