I know we can use the adjective "appealing" in the meaning of attractive and interesting like in the following sentence: "The building design is more appealing to young people." but I wonder whether it more reflects the physical or visual attractiveness of someone or something or it has a general meaning. For instance, Would you say to a professor that "I found many of your research areas appealing to me and I'd like to work as a member of your research group" or it would sound awkward.
It is not just limited to physical attractiveness. Anything that someone could enjoy, they can find "appealing."
