Expected MCB Student Activity by Department
Assumptions
-
Students distribute themselves in laboratories in proportion to the number
of available slots.
-
Total student slots are constant
-
Basic science departments support an average of one student slot per faculty
member (over-and-above MCB slots)
-
Slots and students associated with non-MCB faculty do not affect the dynamics
of students accessible to MCB faculty
-
All laboratories are equally attractive

-
Total MCB student slots = 52
-
Total student slots accessible to MCB faculty = 52 + 43 = 95
-
Total MCB student rotations = 30/yr
Example: Biochemistry
Expectation value for the number of students in the department = (10/83)(95)
= 11.4
Expectation value for the number of MCB students in the department
= 11.4 - 10 = 1.4
Since basic-science faculty are obliged to take departmental
students first, MCB students fill only those slots not occupied by departmental
students. On the basis of faculty representation alone, Biochemistry
would expect to have six [(10/83)(52) = 6] MCB students. However,
that analysis does not take into account the facts that a lab can support
only a finite number of students and that labs in non-basic-science departments
have more vacancies available only to MCB students.
My informal poll finds that Biochemistry trained 5 PhD students from the
MCB Program during the period 1993-1999, and there was an average of three
(3) MCB students in the department at any one time.
After reducing expectations to account for occupancy of
departmental slots, Biochemistry has recruited more than twice the expected
number of MCB students.
Expectation value for the number of MCB student rotations per year = (1.4/52)(30)
= 0.8
My informal poll finds that Biochemistry trained 13 rotation students
from the MCB Program during the period 1993-1999, that is, an average of
2.2 students per year.
Biochemistry has trained more than twice the expected number
of rotation students.
Why doesn't a basic-science department recruit MCB students to the level
of its faculty representation in the MCB program?
Each lab would have to support more students. Departmental fellowships
might be expected to support higher occupancy of basic-science labs.
However, like MCB fellowships, they typically support only the first couple
of years of training. Thus, the number of students per lab may be
limited by extramural funding. Other factors that potentially limit
occupancy include the number of available projects, faculty contact time,
and laboratory resources.
Will unification of recruitment and 1st-year training of graduate students
reduce the number of students in the Biochemistry department?
Yes. The number of students in the department should drop to the
total expected [(10/83)(95) = 11.4], as opposed to the current level (10
departmental + 3 MCB), a loss of two (1.6) students.
