Kebarle was next hired as professor at the University of Alberta, where he continued his high rate of important publications, until his work “disappeared” because of the internalization in the discipline of chemistry. He worked on electrospray MS, publishing with Udo Verkerk what he considers his most important paper. Karl Kopecky is also interviewed, adding his personal recollections of Kebarle. He claims that Kebarle’s work is so important that it forms the core of the subject in all standard chemistry textbooks.

Dean H. Kedes' oral history begins with a discussion of his childhood and family life. Heavily influenced by his father, also a biomedical scientist, Kedes developed an interest in science early in life. He chose to attend Stanford University, pursuing a major in biology with the intention of applying to medical school. Coursework and research in the neurobiology laboratory of Eric Shooter, however, increased his interest in pursuing basic science. Kedes decided to undertake a joint MD/PhD program at Yale University. He joined the laboratory of Joan A. Steitz to study pre-mRNA splicing. Upon earning his MD/PhD, Kedes returned to Stanford University to undertake his clinical residency, though he experienced difficulty transitioning between laboratory research and clinical medicine. Kedes built upon his laboratory research with post-doctoral studies in Donald Ganem's laboratory at the University of California, San Francisco. There he developed his interests in the molecular biology of infectious diseases including Hepatitis B and Kaposi's Sarcoma-associated Herpes Virus (KSHV). He then accepted a position at the University of Virginia. During the interview Kedes reflects on the importance of balancing family life with laboratory work; creating a positive atmosphere within the laboratory; the importance of the Pew Biomedical Scholars Award award with respect to scientific funding and collaboration; and funding in the United States more broadly.

Jack Keene majored in biology at University of California, Riverside. Next he entered Helen Whiteley’s lab at the University of Washington for a PhD in microbiology and immunology.
