I am writing to a university.
Plus, XXX University is doing a great in the researching areas. For example, just a week ago, researchers from this university joined the ESA's Rosetta mission, that will shed new light on how Earth formed.
the researcherd joined the program a week ago from this day. but i don't know when the university will read my letter. so I don't know it is correct to use
just a week ago or English has something else to use in this case.
