  • Senior Research Associate
  • This person is no longer active in the department.


I am currently a senior research associate under Professor Cecilia Mascolo in the Department of Computer Science and Technology at the University of Cambridge. I received the BE and MEngSc degrees in Signal Processing from Northwestern Polytechnical University, China. I received my Ph.D. degree under the supervision of Dr. Vidhyasaharan Sethu and Professor Eliathamby Ambikairajah from the University of New South Wales, Sydney, Australia, in 2018. My primary research interests are on human-centered audio sensing and machine learning for mobile health monitoring, which explores the potential of audio signals (e.g., speech, cough) via mobile and wearable sensing for automatic mental state prediction and disease detection and monitoring (e.g., emotion, depression, COVID-19), and develops generalised, interpratable, and robust deep learning models to improve healthcare delivery.




  • Machine learning in mobile health: exploring the potential and challenges of mobile technologies for health monitoring.

  • Speech and Audio Processing: investigating the advanced signal processing techniques and potential novel applications using speech and audio signals.

  • Trustworthy Deep Learning (DL): improving the interpretability and generalisation of DL for more reliable health outcome predictions.

  • Wearable Sensing: examing novel sensing opportunities for fitness and well-being monitoring with new forms of resource-constrained IoT wearable device forms.





  • Joint/Co-supervision of PhD students working in speech emotion prediction

  • Supervision of master students of thesis projects on speaker verification

  • Supervision of bachelor students of Taste of Research Program in UNSW
