PyData Global 2022

Ziheng Wang

Tony got his BS and MS from a cold dark place called MIT, where he spent years learning the archaic language Verilog. After graduating, he briefly did a startup writing assembly speeding up machine learning model inference. But after discovering most of his prospective customers spend more time loading inputs from a database than actually running the models, he decided to pursue a PhD at Stanford on big data processing.
