I am currently a Ph.D. candidate student under the supervision of Prof. Lu Zhang in Peking University. I was advised by Prof. Dan Ye and Prof. Wensheng Dou in Institute of Software, Chineses Academy of Sciences during my master study. My research interests focus on software engineering, android test, spreadsheet analysis, and machine/deep learning.

Research Experience


  1. Semantic Table Structure Identification in Spreadsheets, 05/2021-05/2020
    • Research problem: spreadsheet tables are usually organized in a semi-structured way, and contain complicated semantic structures. Lack of documented semantic table structures, existing data analysis and error detection tools can hardly understand spreadsheet tables.
    • Contribution: We propose Tasi (Table structure identification) to automatically identify semantic table structures in spreadsheets. We further propose TasiError, to detect spreadsheet errors based on the identified semantic table structures by Tasi.
  2. Learning to detect table clones in spreadsheets, 09/2019-05/2020
    • Research problem: Table clones in spreadsheets are common. Precisely extracting table clones can benefit data reuse, fault detection and data mining. However, table clones are not recorded during the creation of spreadsheets.
    • Contribution: We propose LTC (Learning to Detect Table Clones), to automatically detect table clones with or without structure changes. LTC can achieve a highly precision and recall in table clone detection, significantly outperforming the state-of-the-art technique.
  3. Spatial-temporal video quality assessment (Intern project), 11/2016-12/2017
    • Research problem: This project aims to perform video quality assessment which benefits video codec and compression.
    • Contribution: We improve the JND image quality assessment algorithm in three aspects and get a new video quality assessment algorithm.
  4. Infrared face recognition system based on deep learning (Research competition), 11/2016-08/2017
    • Description: This project aims to improve face recognition caused by the camera's unclear face captured in the low light environment at night. This project can be used for field security monitoring.
    • Approach: MTCNN is used for face detection, and the infrared recovery framework is built on the GAN network. The face recognition system is modified from the Google FaceNet framework.
  5. A City Roadside Parking System (Research competition), 11/2015-08/2016
    • Description: This project aims to solve the problem of roadside parking, and the public cannot find roadside parking space.
    • Approach: We use ultrasonic sensors to determine whether the parking space is occupied, and we have designed a WeChat service number to check the parking space around the user at any time and make an appointment for certain parking spaces.
