I am researcher (Assistant professor ) in computer science. I work on topics which takes more than one year to publish a single paper. Due to my interest I work in these kind of topics. There is one problem which I am facing due to my interest which is as follows. I will not able to advise lots of students due as the field in which I work is not hot and publication takes longer time. I came to academia with a mindset that I will advise as many students as possible. I feel motivated when my graduate students discuss research problems with me and other kind of discussions also. Due to my field in which I am currently working I can only advise one graduate student. The one solution which comes to my mind is to pick a hot topic and start working on that topic and then many students will approach me but I may not be that much interested in these kind of topics.
Question : How to guide more number of graduate students?
Note that the meaning of 'more number' is to advise roughly like 13-15 students in the entire career. I am also interested in producing quality students instead of just quantity.
