Most days, Ben Krog works in the University of Iowa’s Translational Research Incubator — TRI, for short — alone. Four start-ups attempting to commercialize university research are signed up to use the incubator. The university set up the small, on-campus incubator exclusively for spin-out companies that need access to a lab environment but aren’t big enough to need their own space. The sole full-time employee of one of those start-ups, SynderBio, Krog typically has the space to himself as he works on the company’s device to separate benign cells from malignant cancer cells.
