The Mathematics Department offers personalized academic advising for all OSU students, including undergraduate math majors and non-majors.

Advisors are available during drop-in advising hours or by appointment and can provide a broad variety of advising services, including assistance with scheduling, lower division program planning, and signatures on a variety of forms and petitions.


Drop-in advising appointments are for quick services, for example discuss obtaining an S/U in a course, questions about course transfer credits, or adding a math minor. Drop-in advising is for quick (less than 5-10 minutes) questions only. If you need to add a math major or get a registration PIN, you will need to request a longer appointment below using the form below.

To request a prerequisite override for a course, complete the following form to request a prerequisite override.

To request OSU credit for a mathematics course you took at another institution, please complete the Mathematics Course Transfer Equivalency Petition.

  • There are No Drop-in advising hours during the Summer, but students can request an appointment, as advisors are still available - see below:


    Math Advisors are still available for appointment via Zoom or phone for services such as change of major, adding a minor, future term planning, need a PIN, etc.

    If you have questions, or want to contact an advisor directly, you can send an email to To contact an advisor by phone, please call the main office in the Math Department at 541-737-4686.

    MATH MAJORS/MINORS: (Current or Prospective)

    • For early career math majors or minors (taking 100 or 200 level MTH courses), lower division advisors offer program and scheduling advice, and can provide signatures (e.g. change of major/minor forms) and registration PINs. Please use this form to make an appointment with an advisor.
    • Students who are taking 300 and 400 level MTH courses should consult with a member of the Undergraduate Advising Committee. These are the tenure/tenure-track faculty members listed below.  Please use this form to make an appointment with an advisor. These professors can help you with questions about your program, provide signatures or registration PINs, and work with you on career and graduate school planning. Please contact the advisor corresponding to your last name as noted in the table below (including if you are in the Actuarial Science minor).
    • If you are in the Secondary Teaching Emphasis option, please contact Prof. Mary Beisiegel.
    • If you are in the Applied and Computational option, please contact Prof. Nathan Gibson.
