Stanford’s RegLab designs real-world scientific experiments to test the outcomes of government interventions, figuring out what works — and what doesn't. Derek Ouyang is a research manager there and he also co-founded City Systems, an organization that explores potential fixes to municipal problems. From deploying Spanish-speaking contact tracers to developing a low-cost kit to turn garages into apartments, Ouyang is exploring equitable solutions to local cities’ most intractable challenges. And he has some ideas about how to fix San Francisco’s problems, too. | Unlimited Chronicle access: sfchronicle.com/podFixing Our City is part of the San Francisco Chronicle’s SFNext ProjectGot a tip, question, comment?
