If you believe you already have access to MSI, try logging into the the MSI website using your UMN Internet ID and the associated password. MSI usernames and passwords are the same as your UMN Internet ID and password.
Also, your Principal Investigator (PI) or PI-designated Group Admin can log into myMSI and look up your username in the group.
If neither of those options works, MSI staff can also find this information. Email us (firstname.lastname@example.org) and provide your name and the name of your research group's PI.
