Often at JGLS we hear professors and admin say "Dr Sahni's decision is this", "Dr Sahni wants that" etc. At every other event the VC says "Thanks to Dr Sahni", "All because of Dr Sahni" etc. But what is Dr Sahni's exact role and why is he so influential? His official bio (as seen below) says that he is a Member of the Governing Body and Advisor to the Vice Chancellor, plus he was Head of HR at Jindal Steel before joining JGLS. But this still does not explain why he is so influential. He is not a lawyer and has a PhD from Punjab University in psychology. Does anyone have the inside story here?

He's Naveen Jindal's eyes and ears on the ground, and as such has a greater authority and arguably even more power than raj
Yes, he is the link between the VC and Naveen Jindal, much more powerful than the VC. He is the final word on finances, scholarships, faculty hires, promotions, everything.
I see...you have taken inspiration from our India Gandhi. Can we prophesize something like an emergency in jgls with this๐Ÿ˜Š๐Ÿ˜Š
As others have already said, he's very close to Naveen Jindal and that's the only reason he's there. Sort of, to counter the VC's power and balance it (read: make sure VC doesn't become more important than the university itself/Jindal himself).

โ–ฎโ–ฎโ–ฎ though he had worked briefly in SAI and describes himself as a "former bureaucrat" - โ–ฎโ–ฎโ–ฎ

โ–ฎโ–ฎโ–ฎ draconian measures of campus that are implemented actually come from his office (not sure if this is true still, I'm talking about 5+ years ago). He was also quite openly against Murthy, the then-Registrar. All-in-all โ–ฎโ–ฎโ–ฎ

He also has an acute lack of how modern education is supposed to work, a university's role in a student's life, and what a student's liberties are/mean. In my assessment, if permitted to hit students with canes like they do in government schools, he'll implement it.
โ–ฎโ–ฎโ–ฎ taken his elective. Thankfully I wasn't one of them. If this guy is not longer part of JGU. Then it can make huge strides of progress. Sahni and the current registrar are the ones holding the university back. Murthy was a really good guy.
DR sahni is like an employer and Raj an employee. Board chairman and ceo of company kind of.. Raj reports to Sahni. Period.
To use GoT language, it's like this:

- Naveen Jindal: King

- Sahni: Hand of the King

- Raj: Knight
