Cayuse Human Ethics

Cayuse Human Ethics is a web-based protocol management system that is used by investigators, ORCA staff, and IRB committee members. Investigators use it to prepare, submit, and route all initial human subjects research studies, as well as make modifications, request renewals, and report incidents.

Create a Cayuse account

Study team member information

Some places in Cayuse Human Ethics (like the “Research Personnel” section) display information about people. If the name, phone, or organization (department or unit) shown for a person needs updating, use the Cayuse Request form and choose option “Update User Information.” 

  • Name used is the person’s lived name. Instructions for changing lived name
  • Email address in Cayuse needs to be the person’s assigned CruzID@ucsc.edu, not an email alias. If a different email address than expected is shown for a person, confirm their assigned CruzID before submitting a request to update information.
  • Address is always the main UC Santa Cruz campus address.
