Brian Miller is an Instructor for Campus Harvest, “a division of Every Nation Ministries, a member of the Evangelical Council for Financial Accountability,” and travels around giving lectures on science “from a faith perspective”, such as “Empirical Evidence for the Resurrection of Jesus Christ” (this is relevant). Now, Miller does have a PhD in physics, which – despite being utterly irrelevant to evolutionary biology – ensures that he is touted as a genuine scientist by creationists, given the obvious dearth of people with genuine credentials among their ranks. Miller is for instance a signatory to the Discovery Institute’s petition A Scientific Dissent From Darwinism. Of course, apart from a couple of letters and workshop presentations coauthored with his advisor during his student days, we have found no real research record and hence no indication that Miller is actually a scientistin any legitimate sense of the word. You can see Brian Miller discuss Intelligent Design with pastor Ron Lewis here. The advertisement reads: “Still confused if Darwinism is a fact or a theory? Is Science the friend or foe of your faith? Actually, an old adage says, ‘a little of Science can harm a person's faith, but a lot of Science will bring him or her right back to God.’”
More recently, Miller has written extensively for the creationist blog Evolution News and Views. As you’d expect, the writings mostly recycles creationist PRATTs. There is a thorough criticism of some of Miller’s posts here.
Diagnosis: Pseudoscientist, denialist, fundamentalist, and conspiracy theorist. One of many, but unlike most Miller could, given his legitimate credentials, be confused for someone with something worthwhile to say (and the DiscoTute apparently wants to make damn sure that such confusions happen). He isn’t. Move on.
