Welcome to my homepage!

I am an applied research scientist at Amazon Search (A9.com). Before that, I received my PhD degree in Systems Engineering from University of California Berkeley, College of Engineering in May 2018, under supervision of Professor Alexei Pozdnoukhov. Before coming to Berkeley, I obtained my B.S. degree in Urban Informatics and secondary B.A. degree in Economics at Peking University in June 2014.

I am skilled in formulating the machine learning problems and prototyping scalable solutions. I specialize in:

  • general DL: weak supervisions, self training, data augmentation, model calibration, multi-task & meta learning

  • problems: extreme multi-label classification, information extraction, semantic parsing (named entity recognition & entity disambiguation & end-to-end entity linking), ranking

  • sota pretrained models in computer vision & natural language processing
