Douglas Williams is a Pre Doctoral Fellow at Harris School of Public Policy at the University of Chicago. Colleagues describe him as "We hit the jackpot when Doug accepted our offer for a mentor position for the Data4All Bridge Workshop. Doug is truly extraordinary: He has exceptional computational knowledge, a solid grasp of statistics, and the rare capacity to integrate both with scientific reasoning. On top of that, he can explain all of this in an intuitive way, with 100% commitment. His students requested not to be transferred to any other mentor. He is engaging, an amazing team player, and wicked smart. Already has the professional skills you need post-graduation. He has a standing offer from us to be re-hired for any future workshop. If you have a chance to work with Doug, don't miss it!"
