What I mean by creationist plant is this -
From what I can determine, Mr Armitage received his education from two primary sources: Liberty University and the Institute for Creation Research. He also had a stint at Florida State University, but doesn't seem to have completed anything there.
Liberty University is a evangelical Christian university which requires a 'Christian Life and Though' component of almost any biology degree, which includes segments on creationism, the "origins controversy" and a literal reading of the Bible with a young earth, creationist bent. Its biology department is associated with creationist propaganda mill Answers in Genesis. It's less of a university and more of an alternative universe created for biblical literalists to inhabit.
The Institute for Creationist Research is an apologetics ministry that seeks to hid behind the facade of an educational institute. Its graduate programmes have repeatedly failed to secure accreditation. The only organisation it is accredited with was Transnational Association of Christian Colleges and Schools (TRACS) - which ICR/John Henry Morris formed for the explicit purpose of getting US Department of Education accreditation for the school. ICR has been unaccredited since 2008, after it moved to Texas, and the Texas Board of Education rejected, twice, its accreditation (as TRACS isn't recognised in Texas). ICR's legal appeals about this - based around "religious discrimination" were rather curtly dismissed in court.
Mr Armitage has been a creationist for probably 30-years. He is is a lifetime member of the Creation Research Society, serving on its board since 2006. Before California State University Northridge, employment, I can find he worked at:
The Master's College - a biblical literalist university that grew out of a seminary;
Azusa Pacific University - an evangelical Christian university;
Van Andel Creation Research Center at the Creation Research Society - a creationist apologetics mill;
Creation Science Fellowship - a creationist apologetics mill.
So, you have a life-long creationist, educated at creationist ministries, working at creationist friendly universities and/or creationist ministries/apologetics institutions, who takes his apparently quite considerable skills with a microscope and goes an works for CSUN.
Plugging him in to CSUN gives a veneer of legitimacy to anything that he works-on/publishes from that point.
The university, or individuals within it, objects to the implications of having a hard-core, 6000 year-old earth, biblical literalist telling students about his unscientific conclusions and fires him as a result.
Either way, creationist win.
Either he continues to work and publish while at CSUN, giving him legitimacy by association or he gets fired for teaching young earth nonsense/using the university's name in what is seen as an inappropriate manner, and he (and the rest of the YEC community) gets to play the martyr.
Hopefully, CSUN's lesson (don't employ YEC loons in a scientific role, particularly in anything related to biology) is one that is widely shared across the educational panorama.
