Translation of meticuloso

I would rather like that you write through the messaging system on this site and not to my private email address. All the info is gathered here online and I would like to keep is this way. It is nothing personal.
I will be creating an additional study with a student (his name is Juan), which may appear in local newspapers in the future (in English). However, this may take a couple of weeks too.
I will be doing my second year of studies abroad, probably in Panama. For that I will really want to learn Spanish. I know little about the Spanish language, but I will learn. I can help you with German.
