The program was established in 1969 and graduated its first students in 1971. Jamieson was its second director, and he led the program from 1974 to the present, except between 1983 and 1992, when he served as chair of the Department of Cell Biology.Under Jamieson, the program has increased from about 10 new trainees per year to its current level of 20. For the 246 individuals who have completed their training, 192 hold full-time academic positions and about 75 percent of those have or have had research funding.
