Welcome! I am a Ph.D. student at Computer Vision for Human-Computer Interaction Lab (CV:HCI), Karlsruhe Institute of Technology (KIT), Germany, under the supervision of Prof. Rainer Stiefelhagen and Prof. Kathrin Gerling. I received my B.Sc. degree from Guangdong University of Technology (GDUT) and M.Sc. degree from KIT.

My research topic focuses on assistive technology in the background of computer vision. More specifically, I dive into computer vision for scene understanding and embodied AI, especially vision-language navigation for people with visual impairments.

For KIT students who have passion for deep learning / computer vision / embodied AI / assistive technology and are looking for a bachelor / master thesis, please don’t hesitate to contact me with your transcript and curriculum vitae.

Topics include but are not limited to:

• Scene understanding, e.g., semantic / instance / panoptic segmentation
• Vision and language, e.g., vision-language navigation
• Embodied AI
• Assistive technology
• Human computer interaction
