Collaboration

As competition in the research and development field intensifies, deep collaboration has become the trend. Although the gap between the rich and the poor continues to widen, moral principles remain unchanged throughout time. Along the volatile research path, I would be happy to collaborate with like-minded individuals to achieve shared aspirations.

For Students

We always welcome visiting students for collaborative projects, e.g.,

We offer monthly stipends and a dedicated small-scale research project tailored to your interests.

As of September 2024, my group has a couple of master’s student positions available.

For those interested in pursuing doctoral programs, I am happy to recommend you to esteemed research groups within our state key lab.
