He could use a ghostresearcher. Most of his claims are rather dubious.
There's no shame in it: academics have grad students, who at least sometimes get a mention in the acknowledgements.
In what field????? In fields I'm familiar, whoever does the research (i.e. the grad student or the postdoc) is the first author, helpers are co-authors and the PI i.e. the main academic who leads the lab is the last author. In what field PI is the first author and grad students "sometimes get acknowledgement"? That sounds like academic fraud.
I'm not sure where that might happen or be tolerated, today. If you go back and look at research into antibiotics, DNA, etc. back in the 1940s and 1950s ... and even research in the 1960s and 1970s, decades later, there ended up being serious questions around ethics, authorship, etc. for some really seminal papers, for example.
