COVID-19 Policies

Cornell has COVID-related policies with which visitors to campus and events are required to comply. These are being updated periodically.

Presently (28 April 2022) visiting researchers who will be on campus for no more than one business week are encouraged test for COVID-19 before they visit. Masking is required in lectures.

Scam Warning!

Many conferences have been targeted by scammers who claim to be booking accommodation but in reality are seeking to obtain credit card or banking information fraudulently.
