RE:Principal investigator...Sorry wildbird, Mandel wasn't CEO for 6 years. Shirazi resigned 8/21. then Trikola was named CEO, that lasted about 3 monbths until he was let go. Mandel was then named CEO until a few months ago when Roger took over, so Mandel was CEO for 2 years and a few months, not 6 years. So during that period they had 4 CEOs, not 2..
