About Me

I am a CSC (China Scholarship Council) Imperial fully funded PhD student with Dr. Nir Grossman. I graduated from Xidian University in 2017 and then MSc with distinction from Imperial in 2018, all specialising in engineering and signal processing. And now, I am very eagerly applying my engineering expertise into the neuroscience research, through better understanding of brain signals and machine learning techniques.

Research Interests

My PhD focuses on using novel feature-based signal processing technique combined with machine learning to better understand brain signals and exploring mechanisms. Specifically, we are trying to use neuro-modulation techniques to intervene brain activities and facilitate restorative sleep in dementia patients. Novel feature-based analysis approach will be implemented in such brain activity analysis (normally spatio-temporal EEG), and machine learning algorithms are used to find out mechanisms in neuro-intervention, which in turn directs us to optimise the stimulation for better outcomes.
