Dear Colleagues,

We are delighted to announce that the 31st International Complement Workshop (ICW 2027) will be held in New Delhi, India, from 18–23 September 2027. We warmly invite you to save the date and join us for what promises to be an exciting scientific gathering.

To make your visit even more memorable, a one-day excursion to the iconic Taj Mahal in Agra is planned for 17 September 2027.

While the formal registration portal will be launched shortly, we encourage you to visit https://icw2027delhi.org and register your interest in attending. Your early registration for updates will ensure you receive the latest announcements while helping us plan the workshop logistics more effectively.

We look forward to welcoming you to New Delhi in September 2027.
