John G. Cramer is Emeritus Professor of Physics, University of Washington, Seattle. He has had five decades of teaching and research in experimental and theoretical nuclear and ultra-relativistic heavy ion physics, including work at SPS/CERN and RHIC/Brookhaven. He has also worked in the foundations of quantum mechanics and originated the transactional interpretation of quantum mechanics, described in detail in his book "The Quantum Handshake" (Springer, 2016). He is a co-author of over 300 scientific journal publications, over 141 conference-proceeding publications, and several chapters in multi-author nuclear physics books. John has written “The Alternate View” science column in "Analog Science Fiction and Fact Magazine" (1984 – present), as well as three “hard” science fiction novels: "Twistor" (Morrow, 1989), "Einstein’s Bridge" (Avon, 1997), and "Fermi’s Question" (Baen, 2023). John has recently focused on human aging, seeking to understand its causes and treatments. He is a volunteer for the first human trial of large-volume mitochondrial transplantation, to be conducted soon. John was born in Houston, Texas, on October 24, 1934, and was educated in the Houston Public Schools (Poe, Lanier, Lamar) and Rice University (BA-1957, MA-1959, PhD-1961). He was a Postdoc and Assistant Professor at Indiana University (1961–1964) before joining the Physics Faculty of the University of Washington.
