I'm not a huge fan of Dr Walker, and we actually compete with the company he is a "co-founder" of, but I think saying he committed research misconduct is going a bit far.
Misconduct is probably overstating it, and he wrote a popular book, which increased awareness of sleep health.
Did he publish falsified data in a peer review science journal, or did he publish re-interpreted graphs in a scientific literature book intended for the public at large ?
