Abe Singer

Abe Singer, NERSC

As a new security analyst in NERSC’s Security and Networking Group, Abe Singer will be helping with security planning, implementation, monitoring, and incident response.  His main project right now is overseeing our implementation of the Department of Energy’s (DOE’s) Multi-factor Authentication mandate. 

A native of Riverside, California, Singer has spent much of his career in academic and scientific computing environments, mostly working on National Science Foundation (NSF) projects.  Before coming to NERSC, he was the chief information security officer for the Laser Interferometer Gravitational Wave Observatory (LIGO), which was based at Caltech and partly funded by NSF.  And prior to that, he was the San Diego Supercomputing Center’s computer security manager. He also wrote the first book on system logging, taught tutorials for Usenix, taught security classes at UCSD Extension and been an invited speaker at numerous conferences.

Singer notes that his interest in computing sparked between eighth and ninth grade when he took an introduction to programming course at UC Riverside. “We learned to program turtle graphics in UCSD Pascal. It was all downhill from there,” he notes. “I started spending all my free time in the computer lab teaching myself to program. I had the great benefit of getting unofficial mentoring from the CS grads working in the lab, which gave me a strong foundation for understanding good programming.”

After high school, Singer left Riverside to attend UC San Diego where he spent a couple of years studying electrical engineering, but eventually earned a Bachelors degree in composition and music technology. In his free time, Singer enjoys doing yoga, dancing the Argentine Tango, rock climbing, kayaking, surfing, riding his motorcycle and traveling. He is also learning to ice skate.    ​

Rebecca Totzke, NERSC

This month, Rebecca Totzke joins NERSC as a project coordinator. In this role, she will provide logistical support for the NERSC-9 and NERSC-8 projects, essentially ensuring that they meet the missions and requirements of the DOE Office of Science.

Before joining NERSC, Totzke spent 13 years as the Association Manager for the American Peptide Society, a non-profit membership society of approximately 1,200 peptide chemists, scientists and enthusiasts. In this role, she engaged with member scientists, presented financial reports, wrote and edited articles for web content, and served as the APS liaison at biennial Symposiums.

Originally from Albuquerque, New Mexico, Totzke earned her undergraduate degree in mathematics from the University of New Mexico. And, she is currently working toward a graduate degree in mathematics and computer science from the New Mexico Institute of Mining and Technology. She will be continuing her education remotely as she relocates for the job at NERSC.

In her free time,  Totzke enjoys taking long walks with her dog Rivkah and looks forward to exploring trails in the Bay Area. 


About Computing Sciences at Berkeley Lab

High performance computing plays a critical role in scientific discovery, and researchers increasingly rely on advances in computer science, mathematics, computational science, data science, and large-scale computing and networking to increase our understanding of ourselves, our planet, and our universe. Berkeley Lab’s Computing Sciences Area researches, develops, and deploys new foundations, tools, and technologies to meet these needs and to advance research across a broad range of scientific disciplines.

Founded in 1931 on the belief that the biggest scientific challenges are best addressed by teams, Lawrence Berkeley National Laboratory and its scientists have been recognized with 13 Nobel Prizes. Today, Berkeley Lab researchers develop sustainable energy and environmental solutions, create useful new materials, advance the frontiers of computing, and probe the mysteries of life, matter, and the universe. Scientists from around the world rely on the Lab’s facilities for their own discovery science. Berkeley Lab is a multiprogram national laboratory, managed by the University of California for the U.S. Department of Energy’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit energy.gov/science.
