My advisor became an assistant professor nearly two years ago. I worked with him for one year but did not publish a paper, and he thinks my progress is too slow. He asked if I want him to assign a new PhD student on this project. After that, he completely ignored me and stopped funding me. I also find our research interests are not a good match. The project he gave me requires something new to him and me, and I think that’s a hard problem which needs more time.
What should I do? I want to change advisor and don’t want him hate me. Should I go to his office directly to talk with him, because he did not reply me after I send him several emails. I am just afraid the bad relationship will influence my reputation in department.
