Stephen G. Simpson's Ph.D. Students and Postdocs

Here is a list of Stephen G. Simpson's Ph.D. students and postdocs.

Simpson's Ph.D. Students

  1. John Steel, Determinateness and Subsystems of Analysis, University of California at Berkeley, 1977.

    (Steel is a professor at Berkeley.)

    [ Although Steel's official thesis adviser was Professor John Addison of Berkeley, the following is a quotation from the acknowledgements page of Steel's thesis. "I owe a great debt to Stephen Simpson, who guided me expertly in the perilous transition from study to research. The results of Chapters 1 and 2, together with less tangible aspects of my research, are a product of Simpson's influence." The thesis consists of three chapters. ]
