Elbert Branscomb received his B.A. in physics from Reed College (1957) and his Ph.D. in Theoretical Physics from Syracuse University (1964). In 1964 he joined Lawrence Livermore National Laboratory (LLNL) as a theoretical physicist but transitioned to biology shortly thereafter, becoming a senior biomedical scientist in 1969. His primary research focus was on inaccuracy in DNA replication and transcription: its biological consequences, the mechanisms by which it is controlled, and how heritable mutation rates might be measured in human populations. In 1986, when the Department of Energy (DOE) initiated a program to map and sequence the human genome, he assumed responsibility for the computational and mathematical component of LLNL's human genome program. In 1996 when the DOE founded the Joint Genome Institute, Branscomb was named its initial director, serving in that capacity until the completion of the first publicly funded 'draft' sequence of the human genome in 2000. From 2000 to 2004, he held the position of Chief Scientist, US DOE Genome Program, in which capacity he assisted the DOE's Office of Biological and Environmental Research in the furtherance of its genomics-related research programs. In recognition of his scientific contribution to LLNL and the DOE he was awarded the Edward Teller Fellowship in 2001. In 2004 he was named an LLNL Associate Director with responsibility for leading its Biomedical Directorate, a position he held until shortly before retiring from LLNL in 2007. Since moving with his wife Lisa Stubbs to the University of Illinois in 2008, he has held the position of Affiliate Faculty, jointly attached to the Department of Physics and the Biocomplexity Theme at the IGB.
Does life exist elsewhere or is our planet unique, making us truly alone in the universe? Much of the work carried out by NASA, together with other research agencies around the world, is aimed at trying to come to grips with this great and ancient question.
“Of course, one of the most powerful ways to address this question, and a worthy goal in its own right, is to try to understand how life came to be on this planet,” said Elbert Branscomb, an affiliate faculty member at the Institute for Genomic Biology (IGB) at the University of Illinois at Urbana-Champaign. “The answer should help us discover what is truly necessary to spark the fateful transition from the lifeless to the living, and thereby, under what conditions and with what likelihood it might happen elsewhere.”
While many ideas about this fundamental question exist, the real challenge is to move beyond speculation to experimentally testable theories. A novel and potentially testable origin-of-life theory—first advanced more than 25 years ago by Michael Russell, a research scientist in Planetary Chemistry and Astrobiology at the NASA Jet Propulsion Laboratory—was further developed in a recent paper published in Philosophical Transactions of the Royal Society B (PTRSL-B), the world’s first science journal, by Russell, Wolfgang Nitschke, a team leader at the National Center for Scientific Research in Marseille, France, and Branscomb.
