Dr. Trung Thanh Nguyen returns to the Institute of Computer Sciences in frame of the StayConnected@HHU Programme

Dr. Trung Thanh Nguyen is working at the Department of Mathematics at Hai Phong University in Vietnam. Mr. Nguyen received his Ph.D. under the guidance of Prof. Dr. Jörg Rothe at HHUs' Computer Science Department.

In frame of the StayConnected@HHU researcher alumni programme of JUNO Dr. Nguyen spent two months at HHU between June and July 2018.

This is not your first time working and researching at HHU: What motivated you to apply for the returning grant as an HHU researcher alumni?

There are two reasons that motivated me to apply again: The first one is that the opportunity presented itself. I did my Ph.D. here and keep coming once or twice a year. Prof. Rothe mentioned this programme and we talked about this chance to come back to HHU. I saw it as a great opportunity. The second reason is work-related. After my Ph.D., I kept working on a research project with Prof. Rothe. But we only got to communicate via e-mail or see each other in conferences. It is easier to work together face-to-face than meeting on Skype.

What is the most exciting thing about working and researching at HHU?


HHU offers great working facilities. And for our research purposes it is great to have so many colleagues and students at the department, so that we can discuss specific problems as a group in the weekly seminars. This exchange of opinions boosts our research.

Could you please tell us a little bit more about this research project?

Right now we are working on multiagent systems and optimization problems. We have worked on these topics before and continue trying to solve open questions of this field.

How exactly does your research project benefit from the Computer Science Department here at HHU and vice versa?

It is important for me to achieve a joint publication with Prof. Rothe. We help each other by reviewing our work beforehand. And I think the department is interested in our research field and wants someone to work on these topics.

Are there already plans for a future cooperation with Prof. Rothe? Would you like to come back to Düsseldorf?

I actually don't know, but I would like to come back every year. We have talked about how we can apply for funding with our project at the German Research Foundation. Vietnam and Germany have recently signed an agreement that facilitates the scientific cooperation between both countries. Our government funds Vietnamese researchers to work in cooperation with researchers in Germany. And it also works the other way around, so that German researchers receive funds from the German Research Foundation and get to travel to Vietnam and we can work together on one topic. We would like to apply to this programme as soon as possible.

What could we do to make the research cooperation with HHU even better?

When I came here I received all the support I needed. The department also provided all the materials and infrastructure required for my work: HHU has a great library and I even got an office, so I have everything I can possibly need.
