Area(s) of Research

Currently, the main focus of his group is the development of tools (iDEP & ShinyGO) and resources (pathway databases) for the interpretation of large genomic data. Another emphasis is using AI, especially Large Language Models like ChatGPT, in helping analyzing and visualizing data.

Applications of Research

Bioinformatics tools (iDEP, ShinyGO) developed by Dr Ge's group have been used hundreds of thousands of times by scientists across the world to study various processes ranging from agriculturally-important crops to human diseases such as cancer.
