Yeah a professor’s blog post was shared recently that he only felt safe to disclose his caste once he had achieved tenure, and that basically every CS professor of South Asian descent in North America is from the higher castes (as in, the number who aren’t is in the single digits).
Do you mean in India? If you don't mind can you tell me what years those were? I just want to see if I happen to live in a bubble or it was a different time (as in, sufficiently long ago for me to not see it).
The academic phase was during my PhD between 2009 and 2017 in Texas. Upper Caste Hindu professors (2) and fellow grad students and postdocs (2). The professors thankfully weren’t my advisors, but made it their business to pester every Indian student during poster presentations if they found they were not upper caste or weren’t behaving as one (by eating or dating habits).
You can absolutely still report them, if you’re no longer in the university they don’t have much power to influence your career anymore.
I think you might have too much faith in the HR departments of Texas universities :)
UT Southwestern is quite famous for protecting its image at all costs.
