In this interview, David Zierler, Oral Historian for AIP, interviews Kandice Tanner, Stadtman Investigator at the National Cancer Institute, National Institutes of Health. Tanner recounts her upbringing in Trinidad and Tobago, and she shares that her mother "knew" she was going to be a physicist before Tanner herself decided on this career track. She describes how her abilities in math and science prompted her to go to the all-boys school for high school, and she discusses the factors and opportunities leading to her undergraduate studies at South Carolina State University. Tanner describes some of the cultural adjustments coming both to the United States and to attending a historically Black college, and she explains how an encounter at a conference of the National Society of Black Physicists led to her acceptance to the graduate physics program at the University of Illinois-Urbana Champaign. She describes her research in biophysics under the direction of Enrico Gratton and she discusses her dissertation on the deconvolution of spectral photonics of a mammalian brain. Tanner discusses her postdoctoral work at University of California, Irvine where she worked with Bruce Tromberg on building a joint microscope that did optical tomography and two-photon microscopy. She describes her subsequent work at Berkeley in Mina Bissell's lab, which is where she developed her career interests in cancer research, and she discusses the formative effect of Ken Yamada's work. Tanner explains the attractions that led her to join the NCI, which offered unparalleled advantages of in vivo research. At the end of the interview, Tanner describes her current research on breast cancer and glioblastomas, and she explains why she wants to focus her research in the future on immunotherapies as among the most promising avenues in cancer treatment.
