Now that the Roche acquisition of Genentech has been completed, a lot of Genentech scientists will have to decide whether to stay with Roche or not. Roche management has said that they will not do anything to change Genentech’s scientist-friendly culture, but I believe that a lot will depend on what former Genentech CEO, Art Levinson, will ultimately end up doing. Art, himself a former scientist at Genentech, is much beloved by all of Genentech, not just R&D. If his role is diminished or if he leaves, many of the scientists will probably take their money and leave. In the not too distant future, there might be a lot of top research talent available for smaller biotechnology companies to pick up.
