Quanquan Gu

I am an Assistant Professor of Computer Science at UCLA. My research is in statistical machine learning, with a focus on developing and analyzing nonconvex optimization algorithms for machine learning to understand large-scale, dynamic, complex and heterogeneous data, and building the theoretical foundations of deep learning. I am leading the Statistical Machine Learning Lab. I received my Ph.D. degree in Computer Science from the University of Illinois at Urbana-Champaign in 2014.

I am very fortunate to have received a couple of awards for my work, including Yahoo! Academic Career Enhancement Award (2015), NSF CAREER Award (2017), Salesforce Deep Learning Research Award (2018), Adobe Data Science Research Award (2018), Simons Berkeley Research Fellowship (2019), and AWS Machine Learning Research Award (2020). Here is my latest CV.

News and Annoucement

• [March 28, 2020] We just launched a project using machine learning and AI to combat Covid-19!

  We just launched a project (https://t.co/33PBBiuUIr) using machine learning to better understand the spread of COVID-19, to facilitate informed decisions by policy makers, and to better allocate the medical resources. More results are coming soon! @CS_UCLA @UCLAengineering @UCLA pic.twitter.com/MbZ2wHLlwK
