Can a Staff Scientist officially supervise a student?

Staff scientists on their own are not allowed to supervise masters (M.Sc.) or doctoral (Ph.D.) graduate students. However, Senior Staff Scientists and Senior Research Fellows are allowed to co-supervise students, together with a professor. Each case must be approved by the Dean of the Feinberg Graduate School. In any case, staff scientists are encouraged to include in their C.V. a section listing all students whom they have "unofficially supervised," as well as in their work plan when applying for a promotion and tenure.
