I am a principal scientist at Apple. Previously, I worked at ByteDance as head of the applied machine learning (AML) research team. Even earlier, I worked as a research scientist at Google. Even even earlier, I received my PhD from Computer Science Department, Princeton University, working with Prof. David Blei. We mainly work on on-device, federated & privacy-preserving learning as well as other ML innovations for different applications. Please let me know if you are interested. email: mr.chongwang@[companyname].com
