The UC Irvine Sue & Bill Gross Stem Cell Research Center will host a “topping out” barbecue Friday, Oct. 16, to celebrate reaching the halfway point in the construction of its new building. Center co-directors Peter Donovan and Hans Keirstead and Vice Chancellor for Research Susan Bryant will speak at the event. Faculty members and postdoctoral researchers funded by the California Institute for Regenerative Medicine also will attend. The barbecue begins at noon at the construction site next to Hewitt Hall. The building – Sue & Bill Gross Hall: A CIRM Institute – is scheduled to open in 2010.
