Contacting the CNDA Help Desk
Contact Options
Via email
Send an email to [email protected]. Email is by far the best method to reach us and receive help.
We discourage sending PHI through email, but sometimes it might be necessary to document an issue. Sending email with PHI from your WUSTL email account to the cnda-help email address is allowed. Do not send email from a non-WUSTL account (e.g., gmail) with PHI to cnda-help or any other destination.
Via phone
The CNDA team no longer has a telephone number. You are welcome to send a note to the email address above and request a video call.
Via the CNDA Site
