Short Courses: 18-19 October 2025

Fundamentals of Powder/Granular Rheology and Flow (a one-day short course)

October 18, 2025 (Saturday)

Applied Powder Rheology (a one-day short course)

October 19, 2025 (Sunday)

Participants have the option of taking a two-day short-course bundle at discounted costs.

All classes will begin at 8:30 am in Hilton Santa Fe Historic Plaza.

The short courses are held in conjunction with the 96th Annual Meeting of The Society of Rheology (October 19-23, 2025). Check out the lodging information page.

In addition to in-person participations of the short courses, we are also offering online participations. The online participants will access live streaming of the real-time lectures synchronously.
