Or maybe KBLB hasn't told Joe they no longer have a scientific advisory board. Or perhaps he hasn't updated his page on LinkedIn. When was the last scientific board meeting? KBLB hasn't reported any meetings or payments to board members, have they?
He last worked for DuPont in 1991 according to the same web page. That is 31 years ago. I'm pretty sure most of his contacts there are gone by now. If I was a big company that wanted to buy out a startup for billions of dollars, I'd send someone a little closer to the current company structure.
