It appears that "yu" can refer to two different things.
Firstly, it can refer to the Yeshiva University website, which is located at yu.edu. This website is the home page of Yeshiva University, a private Jewish research university in New York City.
Secondly, it can also refer to the name "Yu" as in Emilie Yu, a postdoctoral researcher in the Expressive Computation Lab, whose work involves designing software artifacts for creative people, such as a desktop 2D frame-by-frame animation tool and a VR painting application.
However, without more context, it is difficult to determine which "yu" the question is referring to. If you could provide more information or clarify which "yu" you are asking about, I would be happy to try and assist you further.
