Kathryn Maxson Jones, a seventh-year Ph.D. candidate in the History of Science Program at Princeton University, has recently completed her tenure as a long-term McDonnell Scholar at the Marine Biological Laboratory. Working most closely with Dr. Kate MacCord, she helped coordinate various conferences and seminars in the history and philosophy of science during the academic year 2018-2019. These included an International Society for the History and Philosophy of Biology (ISHPSSB) Off-Year Workshop in October 2018, and the MBL-ASU History of Biology Summer Seminar in May 2019, both focused on regeneration in complex living systems. While in Woods Hole, Maxson Jones was also a member of the laboratory of Dr. Jennifer Morgan, who directs the Eugene Bell Center for Regenerative Biology and Tissue Engineering. Together, Morgan and Maxson Jones direct the McDonnell Initiative Working Group on Neuron Regeneration. Last year, they began a research project on the history and philosophy of the lamprey as a model organism in neuroscience. This intersects closely with Maxson Jones’s dissertation, which focuses on 20th-century neurophysiology and is entitled, “Sea Change: Aquatic Organisms and Neurobiology, from the Neuron Doctrine to the Decade of the Brain.” Maxson Jones will remain with the McDonnell Initiative for the academic year 2019-2020. Amongst other commitments, Maxson Jones and Morgan will present a poster together in October at the 2019 Society for Neuroscience (SfN) annual meeting in Chicago. Based on their collaborative research, the poster explores, “Experimental organisms, neuron regeneration, and the curious case of the lamprey in the history of the neurosciences, 1960-present.”
