(Julia Law and Psychology..) - WHAT'S WRONG WITH THIS SENTENCE?

Having taught Julia Law and Psychology and had numerous intriguing discussions with Julia over the dinner table last summer, this quirky professor leaves no time for boredom.

Having / Had is not parallel.

I'd separate these into two or three sentences.

This quirky professor wastes no time being bored. Last summer he decided to discuss other things besides law and psychology with Julia.

Why is law and psychology capitalized? Also, maybe you could take out the part with the intriguing discussions and stick that into another sentence.also, don't say leaves (present tense) if youre gonna say having taught (past tense) it should be left.

Hello Julia Hou,

Without context, the edit would be this:
Having had taught Julia Law and Psychology to and had numerous intriguing discussions over the dinner table last summer with Julia over the dinner table last summer , this quirky professor leaves (or left) no time for boredom.

Also did she teach Julia over the summer?
