I received a BSc (2009) degree from China Agricultural University (CAU), Beijing, China, an MSc (2012) degree in Signal Processing from Xidian University, Xi'an, China and a PhD degree (2017) in Computer Science from University of Groningen, the Netherlands. I'm currently a Postdoc researcher at the University Medical Center Groningen, University of Groningen, the Netherlands. My current research interests include patten recognition, machine learning, brain-inspired computer vision, and their applications in medical image informatics.
My postdoc research focuses mainly on Medical Imaging Informatics, in which we develop deep learning models for prognostic outcome prediction for head and neck patients. Besides, I also collaborate with several PhD students on the development of Machine Learning algorithms for automatic medical image analysis on early diagnosis of Big-3 diseases in low dose CT scans and mandible segmentation for Maxillofacial Oncology..
Glaucoma is the second-leading cause of blindness. It damages the optic nerve irreversibly and has no early symptoms. The most common clinical measure is the cup-to-disc ratio. In collaboration with the Department of Ophthalmology of the University Medical Center Groningen, we develop more comprehensive methods to be used for large-scale glaucoma screening of the population.
The classification of serrated patterns in direct immunofluorescence images is used for the diagnosis of epidermolysis bullosa acquisita, a subepidermal autoimmune blistering disease of the skin. Together with the Department of Dermatology of the UMCG, we developed an automatic method to classify serrated patterns as u- or n-shaped.
In my PhD research, I focused on brain-inspired computational models for pattern recognition. I proposed an inhibition-augmented trainble filters to improve their ability in discriminating similar patterns.
In collaboration with an Australian university and a research institute, we aim at further improving the performances of the current metric-based few-shot learning approaches for fine-grained image classification..
The automatic recognition of symbols can be used to automatically convert scanned drawings into digital representations compatible with computer aided design software. We propose a novel approach to automatically recognize architectural and electrical symbols.
My research is about brain-inspired computer vision, including computational visual models of feature and object recognition; medical image and data analysis; machine learning algorithms such as deep learning. Specifically, I focus on techniques and extend methods in the field of automatic computer-aided diagnosis system for assisting population based glaucoma screening.
Attended several courses within the MSc of Computer Science at the University of Groningen: Neural Networks and Computational Intelligence, Image Processing, Pattern Recognition. Attended the International Computer Vision Summer School (ICVSS), Italy, 2013.
