Personal profile

Welcome to my page!

 

I am a PhD student researching Machine Learning for WiFi technologies, with applications for indoor positioning.

Supervised by Dr Khuong Nguyen, I joined the Royal Holloway University of London after completing my BSc degree with an 85% GPA at Zhejiang University. I'm a Utility Model Patent owner of a sensor design published in my junior year of undergraduate studies.

Research interests

How about navigating indoors with the same ease as outdoors, using just your smartphone?

 

With the proliferation of WiFi-enabled devices and the growing need for precise indoor navigation, my research interest centres on leveraging machine learning and feature selection methods to enhance WiFi-based indoor positioning systems. Traditional indoor positioning methods often fall short in delivering consistent accuracy due to environmental factors and signal interference. By integrating state-of-the-art WiFi Round-Trip-Time technology and machine learning algorithms, we can model and predict positioning with improved precision. Furthermore, the incorporation of feature selection techniques ensures that the most relevant signal attributes are considered, reducing computational complexity and enhancing the system's efficiency. This synergy of machine learning and feature selection holds the promise of great improvement in indoor navigation, delivering a seamless and accurate user experience.
