I did some looking into this Dan guy early on as his youtube videos were used by a lot of pro-vaxers against any valid suspicions. He was working at pharma in a lab that produced pcr tests. Only real PHD I could find was in "philosophy". He went to carnegie -melon, which as we know is corrupt since early 1900's. He is so annoying and I'm happy to see this take-down of his BS.
