Visiting Scholars: "The brain is too complex, we need to collaborate!"

Updated on:

Bae Hee-Joon is professor of neurology at Seoul National University College of Medicine, neurologist at Seoul National University Bundang Hospital and director of the Gyeonggi Regional Cardiac and Cerebrovascular Centre in Seoul, South Korea. He is a world-renowned specialist in stroke and vascular cognitive disorders. He spent 3 months working at the University-Hospital Institute for Vascular Brain Health (VBHI) and in the Eleanor team at the Bordeaux Population Health (BPH) research centre.

Bae Hee-Joon was welcomed to the Eleanor team by Stéphanie Debette, director of the VBHI. The two researchers study brain vascular health, a major public health issue worldwide. Stroke is the second leading cause of death throughout the world, affecting 100 million people. It is the leading cause of death among women in France and the second leading cause of death in South Korea.

Why did you apply for this programme?

My host and I have known each other for a long time. We have already published together and we want to strengthen this collaboration by raising it to an institutional level. My research focuses on brain health, vascular brain health to be precise. In the past, research focused on Alzheimer's disease and vascular dementia, but today we know that these diseases have a lot in common. To this end, the launch of research initiatives such as the VBHI (Vascular Brain Health Institute) is highly innovative, as it approaches the subject from a different point of view and tends towards transformative research.

At the same time, the Eleanor team at the BPH research centre (Bordeaux Population Health) has introduced a genetic dimension to this research. In cancer treatment, we talk about precision medicine: after analysing the cancerous tissue, we can offer the patient a treatment adapted to the characteristics of their tumour. All this is possible thanks to studies carried out on cancer genetics. But for the moment, this practice is only reserved for cancers and does not apply to the treatment of strokes. We don't have enough information on the relationship between response to treatment and genetics. The BPH team is very advanced in this respect. Their work is in line with the objectives of the GENESIS-K project funded by the Korean government and for which I am responsible. We are trying to establish a link between MRI images, genetic information and the outcome of treatment by analysing treatment reimbursement claims.

Genetic studies require the involvement of a very large cohort of patients. Sharing experience and research collaboration are therefore essential!

How was your mobility experience?

It was very rewarding! I had the opportunity to talk to doctoral students and I hope we can work together in the future. Despite my experience in the field, they taught me a lot! Several students have expressed an interest in coming to Korea, and I hope that Korean students will be able to come here too.

During my stay, I gave a talk at the VBHI to present the GENESIS-K project, which I'm working on. I took advantage of my time in France to meet other partners in Paris and Lille. I also got to know the French way of life! Immersion was a bit tricky at first because of the language barrier and cultural differences. It was a great opportunity and I'd like to thank the University of Bordeaux.

Visiting Scholars programme / visiting researchers and professors

The programme concerns all areas of research, teaching and/or the promotion of new collaborations and international partnerships.

The 2025 campaign has been launched: international researchers wishing to be hosted at the University of Bordeaux for stays of between 1 and 10 months can apply until February 2nd 2025.
