You can declare the Microbiology major at any time in your undergraduate career. You should initially meet with the Student Services Coordinator (Katy France, to discuss the major, the science, and to make a tentative 'road map' for the remainder of your time here at UW-Madison. The department encourages you to schedule that meeting as early as possible, for a couple important reasons. Once declared, you will receive emails from the Student Services Coordinator containing information on course offerings, academic announcements, job postings, career preparation activities/events, graduate and professional school preparation information, and more. Additionally, when you become a Microbiology major, you will be assigned an advisor from the department. You should plan to meet with your advisor each semester.
