I'd like to nominate Ashley Kelly as a yt project member. Ash is working on a google summer of code project this summer on improved support for SPH data in the yt 4.0 branch. He is single-handedly ticking off quite a number of things on our to-do list for yt-4.0 and has expressed a desire to continue working on yt development during his PhD which he will be starting this Fall. He has made significant progress on adding support for "gather" smoothing (see his progress here: https://github.com/yt-project/yt/pull/1828
, in particular the image showing the high image quality you get back using gather smoothing).
As per YTEP-1776 we need three more project members to +1 the nomination, after which I'll give him a commit bit on GitHub and add a stub entry for him on the members page on the website.
