This probably seems a minor quibble, but the first panel in this comic has the wrong preposition. It should be “on” or “about.”
You pretty much need to be a native speaker of the language to get prepositions right all the time (and even then, you can find geographical differences, say, between the US and UK).
I don’t have a good solution, either. Maybe try googling phrases like “preposition for thesis topic.” Or ask a curmudgeon.
