Message from the Chair

Chihaya Adachi

We have been facing serious difficulties in this year due to COVID-19. My heart goes out to everyone involved in this tragedy, and I have nothing but appreciation to all healthcare professionals out there.

Considering such circumstances, we have made a decision to take a new approach regarding our annual conference. The 5th International TADF Workshop and the 3rd i3-opera Forum, a companion event aimed at industry researchers, will be held in December by means of online live streaming.

The workshop and the forum will be associated with 3D virtual exhibitions and poster sessions as well as with online social gathering. We expect that this attempt to start-up exciting online events will pave a way for our post-coronavirus life with new normal.
