How does closing down a department affect the value of a PhD and your later academic career?
If someone has joined a university for a PhD in transportation, and that department is closed down, and everyone is moved to / absorbed by management engineering , does this have any ill effect on the quality of education that you will recieve, possible research opportunities, publications and academic career in general?
I have read this related QA, but it's about an undergrad student. PhD students have very fewer and much more specialised courses. In addition, a PhD student is supposed to assist in teaching some courses, how is someone with completely unrelated background (transportation/rural/survey engineering) teach management courses? I'm guessing that this curriculum will have some engineering courses as well, but it sounds to me too generic to be of any use to a student (I have never heard of management engineering before today, pardon my complete ignorance).
Given that some of the faculty will either lose their jobs, or quit, I do not expect their courses to be available, thus the available courses for a PhD student will be much worse (irrelevant to the field of transportation). Given that undergrad students have more generic courses, it is possible for someone to teach those, in contrast with the very niche courses of a PhD curriculum.
I should mention that I am posting this in behalf of someone else, who is only 3 months in that university. The person of interest, claims that it matters more to collaborate with a certain supervisor (who is a Computer Engineer, specialising in machine learning), as they had a great relationship and collaboration in the past; furthermore, since computational science courses are available, the lack of transportation courses seems acceptable to that person, but I am afraid about the fact that they are completely unrelated (computational science can be used in any field, from biology to sociology and statistics).
