Elizabeth Holmes told a San Jose federal jury Monday that research with pharmaceutical giants and Stanford University indicated that the technology used by her defunct blood-testing company Theranos was “very reputable.”

The former Silicon Valley CEO’s testimony sought to contradict the government’s criminal fraud case accusing Holmes of defrauding investors, doctors and patients with faulty technology. Holmes’ Williams & Connolly counsel, who unexpectedly put her on the stand Nov. 19 in U.S. District Judge Edward Davila’s Northern District of California courtroom, sought to characterize her understanding of the technology’s functionality between 2008 and 2015.
