About WALS

The NIH Director's Wednesday Afternoon Lecture Series, colloquially known as WALS, is the highest-profile lecture program at the NIH. Lectures occur on most Wednesdays from September through June from 3:00 to 4:00 p.m. in Masur Auditorium, Building 10 on the NIH Bethesda campus.

Each season includes some of the biggest names in biomedical and behavioral research. The goal of the WALS is to keep NIH researchers abreast of the latest and most important research in the United States and beyond. An added treat is the annual J. Edward Rall Cultural Lecture, which features top authors and other cultural icons. All speakers are nominated by the NIH community.

If you are not at the NIH, sign up for the WALS listserv to receive notices about each lecture. All lectures are viewable live at and then later archived here. (For the 2021–2022 season, all lectures are remote-only because of pandemic restructions.)

We hold approximately 35 lecture per year, which includes these named lectures:
