I am an academic as well. Even though I teach at a Business School, most professors never wear a suit, much less a tie. The idea of a SC with a tie is unheard of. So much so even I do not feel comfortable wearing it, so whenever I wear a SC I never use a tie. I reserve those for suits, such as this one below. I can say one thing for tab collar shirts - it really helps to maintain the tie in place during the whole day. No adjustments necessary.
