I am looking for potential PhD opportunites in engineering and I found a potential PhD supervisor. Personally, I plan on entering academia after my graduation. However, it seems that during the past 12 years, the professor had no students staying in academia after their graduation. I also found that some of the PhDs have very good publications in top journals and excellent experience in being a research associate but they all eventually entered the industry or even finance companies.
One reason for this might be that nearly all of these students were sponsored by industry. For me, I wonder if it is normal for a PhD supervisor to have no academic "descendants" in universities or other research institutes and if the professor is suitable for me if I plan to enter academia after finishing my PhD. I would appreciate it very much if you could give me some suggestions on this.
