Dr. Kao can cross majors. However, tutors are generally reluctant to take interdisciplinary students. After all, they need students who can directly help the project. So you'd better communicate with your tutor first. As long as he is willing to take you, there is no problem.

According to the orientation of doctoral study, the main job of doctoral tutor is not to give students a few courses, but to guide students to learn. In other words, the tutor's main job is not to "teach" but to "guide".

1, to guide students to be familiar with the basic theoretical knowledge and methods in this discipline or related fields.

Basic theoretical knowledge and methods in this discipline or related fields are prerequisites for doctoral study and research. Because of the differences in academic background and academic level of doctoral students, it is extremely important to guide students to be familiar with the basic theoretical knowledge and methods of this discipline or related disciplines. Without a basic understanding of the research situation of this discipline and related fields, familiarity with the academic norms of this discipline, and inability to use the basic theories and methods of this discipline and related disciplines to raise and solve problems, there will be no scientific basis for doctoral students' study and research.

2. Guide students to study creatively and improve their research ability.

The main way to guide students to be familiar with the basic theoretical knowledge and methods in this discipline or related fields is to guide students to carry out creative learning, closely combine reading, thinking and research, and continuously improve their research ability, academic taste and research level.
