Overview

Mission

To empower scientists to organize and participate in conferences that offer uniquely targeted content, foster high levels of scientific dialogue and provide a beautiful and relaxing environment for social interaction.

What it reported doing in 2025

The organization sponsors an annual series of conferences for the scientific community which are international in scope and focus on new and emerging areas of all fields of sciences and letters. The conferences are attended by students, researchers, and members of academia and industry. For each conference a book is published on the topics presented at the conference and distributed to the conference participants and sent to any person requesting information on that topic.

Operating model

Revenue model
Earned-program. 91% of the money available for current operations came from fees and other program revenue.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

SUPPORTED - A large share of available resources goes toward mission work and most voting board members are independent. The filing reports few safeguards for money sent abroad and the filing does not identify recipients for some grant dollars.
