General Information

All rotations are typically four weeks in length to ensure students receive an optimal neurosurgical experience, with one week spent in each of the following areas: Tumor, Spine, Vascular/Functional, Pediatrics, or potentially at the Johns Hopkins Bayview Medical Center.

The most popular months for sub-internships are June, July, August, and September. If you wish to rotate during these months, early application is strongly encouraged.

All applications must be received no later than two months before the start date of your sub-internship. Example: if your desired time frame for a sub-internship is October 1 - October 31st, your application and supporting documents need to be completed and returned by August 1st.

Completion of a visiting sub-internship is not required to match in our program. Many of our current residents did not complete a visiting elective rotation with us. Although we will give your application every consideration, completion of a visiting subinternship does not automatically lead to an interview.

Please submit an application through this online portal. Please also send your CV and a letter of recommendation directly to Colleen Hickson, Department of Neurosurgery Medical Training Programs Administrator.

Rotation Dates

The Department of Neurosurgery follows the JHMI Academic Calendar with respect to visiting medical students.

Before Your Elective

Students enrolled in U.S. medical schools must have an NPI number before beginning a rotation. Please apply for an NPI number if you do not have one already. Once at website, select the link: “If you are a Health Care Provider, the National Provider Identifier (NPI) is your standard unique identifier.”

You do not need an NPI number at the time of application, but will need it to be approved for a rotation. Please provide your NPI number to the Medical Training Programs Coordinator as soon as you receive it.

On Your First Day

On your first day at Johns Hopkins, you will need to:

  1. Report to the Registrar’s Office to register for your elective. The Registrar is located in the Miller Research Building, 733 N. Broadway, Suite 147.
    Non-US citizens must first check in with the Office of International Services (OIS) before registration can be completed. Please bring all required materials with you when you report to the OIS as well as a letter of good standing from your school and ensure you have all documents required by the OIS. It is helpful for the OIS Check-in Form to be completed before reporting for check-in. Their office is located on the 2nd floor of Reed Hall, 1620 McElderry Street, Baltimore, MD. OIS hours or operation are Monday - Thursday, 8:30 a.m. - 12:00 p.m. and 1:00 p.m. - 5:00 p.m. The office is not open to the public on Fridays.
  2. After registration, obtain a Johns Hopkins Identification Badge from the I.D. Office, Harvey/Nelson Building, Room 108.
  3. Report to Sheikh Zayed Tower, Room 6126 to meet with Colleen Hickson, Medical Training Programs Administrator for the Department of Neurosurgery to:
    a) complete emergency contact information form
    b) complete training and obtain a swipe card for access to the Neurosurgery scrubs machine
    c) complete JHED ID authentication process
  4. Meet with Dr. Timothy Witham, Co-Director, Neurosurgery Residency Program

On Your Last Day

On the last day of your rotation, you will need to:

  1. Return all scrubs to the scrubs machine. Unreturned scrubs could impact availability for subsequent rotators and sub-interns. You will be charged a fee for the cost of replacement for scrubs checked out in your name that are not returned.
  2. Return your swipe card, pager and Hopkins ID badge to Colleen Hickson.
  3. Provide your evaluation form to Colleen Hickson, the Medical Training Programs Administrator.
