Ce Zhang is the CTO of Together AI, which lists Zhang among its founders, and a Neubauer Associate Professor in the Department of Computer Science at the University of Chicago; before that, Zhang was an Associate Professor at ETH Zurich. Zhang's research looks at the tension between data, models, computation and infrastructure, with a focus on machine learning platforms and systems that are data-centric, human-centric and declaratively scalable. Zhang is a co-author of the RedPajama paper, which describes an open dataset for training large language models, and of the Holistic Evaluation of Language Models (HELM) paper. Zhang completed a PhD at the University of Wisconsin-Madison and a postdoc at Stanford, both advised by Chris Ré.1236
