Demanding deep study on behalf of institute (8)

I believe the answer is:

profound

I'm a little stuck... Click here to teach me more about this clue!

'demanding deep' is the definition.
'profound' can be an answer for 'deep' (I've seen this before). I am not certain of the 'demanding' bit.

'study on behalf of institute' is the wordplay.
'study on behalf of' becomes 'pro' (I can't justify this - if you can you should give a lot more credence to this answer).
'institute' becomes 'found' (synonyms).
'pro'+'found'='PROFOUND'

Can you help me to learn more?

(Other definitions for profound that I've seen before include "anything but superficial" , "Overpowering" , "Intellectually deep" , "Showing great insight" , "Far-reaching" .)
