EOL Seminar Series

The EOL Seminars are held on Tuesdays from 3:30-4:30 pm in FL2-1022 or FL2-1001, and are webcast when possible. The seminar coordinator is Ulrike Romatschke (romatsch@ucar.edu), with administrative support from Melissa Ward (mward@ucar.edu). Please contact us if you would like to present a seminar, have a visitor who would like to present a seminar, or have a suggestion for a seminar speaker or topic that we should cover.

During the COVID-19 crisis all our seminars will be held virtually.
