The University Provost establishes minimum pay levels based on the years of cumulative research experience a Postdoctoral Scholar has when appointed. The minimum annual pay for first-year scholars for upcoming 2008-2009 academic year (autumn through summer) is $40,785. For NIH, the minimum salary for new postdocs is $36,996 (as of February 2008).
Departments at Stanford University may establish their own guidelines as long as pay rates meet or exceed those established by the University (as reported in the tables above). If you have questions about pay rates or the pay rate guidelines, please contact the Office of Postdoctoral Affairs.
