Bio
Hello! Welcome to my homepage! I am Yu Wang, a dedicated research scientist specializing in machine learning techniques and theories. I recently moved to San Fransisco bay area and look forward to joining the local academia!
I obtained my PhD degree in Computer Science from the University of Cambridge UK in 2016. My PhD study was co-supervised by Dr. Ian Wassell and Dr. David Wipf (David is my internship mentor at Microsoft Research), with a focus on variational Bayesian inference. I received my postdoc training at the Department of Pure Mathematics and Statistics (DPMMS) of University of Cambridge, UK, co-supervised by Prof. John Aston and Prof. Carola-Bibiane Schönlieb in 2016-2018.
After my postdoc, I respectively worked as a senior research scientist at JD AI research academy working with Prof. Tao Mei, and as a senior research fellow at Tsinghua University working with Prof. Lu Fang.
Research Interests
I love math and CS! My research interests include machine learning theories (and their application on computer vision tasks, language models), generalization theories, generative modeling, self-supervised learning, Bayesian inference, sparse coding, safety of foundation models, and broader statistical machine learning problems.

Hobbies
I love classical music and reading. My favorite music is Rachmaninov Piano Concerto No.2. I am a professional clarinetist, and I also had the honor to be invited to play concert at the “Temple of Music” in Vienna, Austria – Wiener Musikverein, Großer Saal (we were playing Beethoven Symphony No. 8, and Brahms Symphony No. 1.), when I was 16 years old. At the age of 14, I recorded my first clarinet album with a theme on Mozart and Weber. I also enjoy playing piano and saxophone for fun.
