It was our pleasure to welcome Dr. Csaba Hajdu from Széchenyi István University, Hungary and have an opportunity to hold a seminar titled “HyMeKo: One Hypergraph Substrate for Representing and Learning from Structured Systems”.

It was our pleasure to welcome Prof. J Venkatesh from Chennai Institute of Technology, India and have an opportunity to hold a seminar titled “Multi-Agent Systems in Cardiac Surgery”.

We visited the University of Wollongong, our partner institution in this Joint Degree Program.  For the first time, we held a joint seminar in person, which had previously been conducted exclusively online. During the seminar, students gave presentations and received valuable feedback and guidance from professors on both sides.

In addition, we were able to organize student exchange activities, individual meetings, and various discussions, making this visit highly meaningful. We also met with master’s course students who were staying there under our university’s research internship program, allowing us to hear about their current progress.

This was the forth time that an information session for our program (Joint Degree Doctoral Program in Informatics) was held.
At the session, we provided detailed explanations about the Joint Degree Program, our partner institution—the University of Wollongong in Australia—as well as matters related to staying in Australia.
