The Farquhar College of Arts and Sciences Division of Math, Science, and Technology welcomed Ralph Merkle, Ph.D., to Nova Southeastern University as part of the college's Distinguished Speakers Series. Merkle discussed "Life, Death, and Cryonics" on Thursday, October 2, 2008.
A pioneer in computer science for three decades, Merkle co-invented public-key cryptography, the safeguarding of electronic communications using mathematical keys. For his findings, he received the 1996 Kanellakis Award, given by the Association for Computing Machinery for accomplished research in computing.
Merkle also has been at the forefront of research into technologies once considered science fiction, such as nanotechnology (the science of molecular manufacturing) and cryonics (the science of using ultra-cold temperatures to preserve human life with the intent of restoring good health when technology becomes available to do so). Merkle has long been a proponent of nanotechnology as the next stage of manufacturing, in which molecules will be manipulated and rearranged at an atomic level to create new products.
Merkle received his bachelor's and master's degrees in computer science from the University of California at Berkeley. He received his Ph.D. in electrical engineering from Stanford University. He has served as an executive editor of the research journal Nanotechnology and is a former director of the Foresight Institute, a public-interest think tank dedicated to exploring issues of nanotechnology and society. He is co-recipient of the 1998 Feynman Prize in Nanotechnology for his theoretical research into molecular tools for controlling atomically precise chemical reactions. Merkle is currently a director of the Alcor Life Extension Foundation, a leading U.S. cryonics research organization, and has served as chair for several Alcor conferences covering cryobiology, tissue engineering, nanomedicine, and genetic engineering, among other topics. He also is a Distinguished Professor of computer science at the Georgia Institute of Technology.
Merkle's current work in cryonics utilizes his research in nanotechnology to delve into a controversial area of research. According to the Alcor Life Extension Foundation, "Cryonics is a speculative life support technology that seeks to preserve human life in a state that will be viable and treatable by future medicine. It is expected that future medicine will include mature nanotechnology, and the ability to heal at the cellular and molecular levels." The purpose of cryonics is to save lives and restore health, yet it challenges society's definitions of "death" with the underlying assumption that patients declared dead by today's doctors may be revived in the future.
Merkle's visit corresponded with the college's 2008-2009 academic theme of "Life and Death," which united the college's students and faculty to explore the relationship of life and death within social, scientific, legal, religious, and political contexts.
