The Department of Mathematics at the University of California, Santa Barbara invites applications for a pool of qualified lecturers to teach undergraduate or graduate Mathematics courses. Screening of applicants is ongoing and will continue as needed. The number of positions varies from quarter to quarter, depending on the needs of the department. Positions may range from one quarter to one year with the possibility of reappointment depending on performance and further departmental need. The successful applicant will be a broadly trained mathematician who is dedicated to teaching. Further information about Mathematics at UCSB can be found at: http://www.math.ucsb.edu. The posting will remain open until March 31, 2026 to accommodate department needs. The pool will close on March 31, 2026; if you would like to continue to be considered after that time, and the pooled position is advertised again, you will need to submit a new application. Please note: The use of a lecturer pool does not guarantee that an open position exists at the time you are applying. See the next review date specified in UC Recruit to indicate the next potential upcoming opening. If there is no future review date showing, your application may not be considered at this time.
