From Pubmed, it appears that since 2007, he published 6 papers in one lab (likely his Ph.D. lab), including a first author in PNAS, and 4 papers in a second lab since 2013, including the Nat. Neurosci. paper you cite, where he is one of 3 authors.<p>It isn&#x27;t a <i>terrible</i> publication record.  One would have to know the significance of what he <i>did</i> publish in order to judge properly.<p><a href="http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;?term=Gariepy%20JF[auth]" rel="nofollow">http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;?term=Gariepy%20JF[auth]</a>
