Mullan is no longer CEO and President of Roskamp. Fiona Crawford, since sometime earlier this year is now CEO and President of Roskamp.
Of course Mullan is still heavily involved with Roskamp as a researcher/collaborator. He is now listed as simply Founder on Roskamp web site.
Why would he leave a prestigious position as CEO when so much is happening right now at Roskamp to CEO a nearly bankrupt company. He knows there is big potential for anatabine :)
