Researchers invited to the NII who have had outstanding research accomplishments are asked during their stay to give a series of lectures on informatics from the point of view of their own specialties. With such lectures we have been able to acquire specialized knowledge from these researchers and carrying out meaningful exchange with them. The lectures are conducted in English and are open to the public. The lectures are announced in the event open to the public. The lectures are announced in the event information column on the NII's home page.
