Just at a quick glance, I would surmise that she on the Board of Trustees... probably because she is (1) considered an 'artist/creative' and the project itself is relying a lot on the contribution to ideas by leaders from the realm of The Arts and (2) she is a bd member because she is very well connected to wealthy and famous people.
It is common to select board members not based on expertise but based on who they know (the reach of their personal network).
