Rebecca Hartman-Baker, NERSC User Services

Rebecca Hartman-Baker

In January, Rebecca Hartman-Baker joined NERSC’s User Services Group as an HPC User Consultant. In addition to helping scientists use the facility’s machines more efficiently, Hartman-Baker will also help NERSC develop a robust user training program, as well as procure its next supercomputer.

Before joining NERSC, Hartman-Baker performed very similar roles at the Pawsey Supercomputing Center in Perth, Western Australia, where she helped build a brand new petascale computing facility. She led the selection process for determining the architecture of the facility’s petascale machine, called Magnus, and led the user-training program. Prior to that, she spent seven years at the Oak Ridge National Laboratory, including five years at the Oak Ridge Leadership Computing Facility.

Hartman-Baker notes that her passion for computing sparked with an interest in math. “I was always interested in patterns, and using math to make sense of the world,” she says. “As a young child, I was obsessed with calendars, and was always interested in computing (using my perpetual calendar) to see what day of the week a particular date fell on. As an older child, my dad would distract me from my hatred of hiking by asking me to solve math problems as we walked.”

A Kentucky native, Hartman-Baker earned her undergraduate degree in physics at the University of Kentucky and a PhD in Computer Science at the University of Illinois, Urbana-Champaign. In her spare time, she enjoys hanging out and traveling with her husband, eight-year-old son, and soon daughter (due next month. She has also coached two teams in the SC Conference Student Cluster Competition, the first to represent Australia. She also likes playing violin and listening to classical music.

Michael Dopheide, ESnet Cybersecurity

Michael Dopheide

As ESnet’s new Senior Information Security Analyst/Engineer, Michael "Dop" Dopheide will work on all aspects of cyber security from intrusion detection and incident response to helping develop a strong security architecture for the future.

Before to joining ESnet, Dop worked in information security at US Bank. And prior to that, he spent several years working in security operations at the National Center for Security Applications (NCSA).

“I am really excited to get back into a role supporting science research,” says Dop. “I first got interested in computing just about the time when ISPs (internet service providers) started popping up around the country to get people connected to the Internet. My friends and I had to learn how everything worked in order to play games, a strong motivator. It wasn't until the later part of college that I realized I could make it a career.

Originally from Quincy, Illinois, Dop earned his Bachelors Degree in Mechanical Engineering from University of Illinois, Urbana-Champaign. He will continue to live in Champaign, Illinois, while working remotely for ESnet.

In his spare time, Dop trains and helps teach martial arts. He holds a black belt in Jeet Kune Do Concepts and a purple belt in Brazilian Jiu Jitsu. He also enjoys woodworking, a skill he picked up from his father, and traveling to the West Coast with his wife.

About Computing Sciences at Berkeley Lab

High performance computing plays a critical role in scientific discovery. 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.
