Xiaochan Xu, Huixia Ren and Xiang Liu attended the "A3-NIMS Joint Workshop on interdisciplinary Research Connecting Mathematics and Biology" from May 12 to 14 at Daejeon, Korea. The A3 funding strongly encourages research communication and collaboration between China, Japan and Korea (Asia 3 counties). This year the workshop was hosted by National Institute for Mathematical Sciences (NIMS) in Korea. During the 3 days of well-organized meeting, researchers presented their recent progress and engaged in active discussions in many interdisciplinary areas between mathematics and biology, such as computing, modeling, data analysis and dynamic systems etc. All the three students benefited a lot from interacting with other participants. In particular, they were given opportunities to present their own work at the meeting. They also enjoyed the multi-culture atmosphere, and the natural beauty and hot springs in Daejeon.
