Barbara Jacak Steps Down as NSD Director in Return to Research
Longtime nuclear theorist Volker Koch is acting director

Barbara Jacak, a faculty senior scientist who for the past six years led Berkeley Lab’s Nuclear Science Division (NSD), has left that role to devote more time to scientific research, and in particular to R&D for the Electron-Ion Collider (EIC) project, which will be built at Brookhaven National Laboratory. Jacak is also maintaining her academic duties as a physics professor at UC Berkeley.

Volker Koch, a theorist and senior physicist in Berkeley Lab’s Nuclear Science Division (NSD) who has previously served as the division’s program head for Nuclear Theory and deputy director for Low Energy Nuclear Science, has stepped in to serve as its acting director, effective Feb. 1, 2021. A committee will be formed to hire a permanent replacement for the position.

"Under Barbara's leadership NSD has prospered, and she will now be able to turn her full attention to the next generation Electron-Ion Collider project,” said Natalie Roe, Physical Sciences Area director. "I’m grateful that Volker has agreed to take over as interim division director, and know he will keep a steady hand on the tiller."

Excitement over the fast-developing EIC
While Jacak did find some time to participate in QGP research while serving as NSD director, she half-joked that her research career had been relegated to nights and weekends because of the demands of serving as division director.

Her excitement about the EIC project, and the fact that the project is already advancing – its first DOE milestone, known as CD-0, was in January 2020, and its construction will take about a decade – definitely prompted Jacak to consider a return to research at this time. “I expected it would be built,” she said, but not to be at this stage yet. Jacak will also spend some time on the ALICE Experiment at CERN’s Large Hadron Collider (LHC), and a successor experiment to PHENIX called sPHENIX that is expected to begin taking data in 2023 – Berkeley Lab will assemble a detector component for it called a silicon pixel vertex tracker.

Berkeley Lab researchers have been involved in a variety of R&D efforts to support the construction of the EIC, too. Jacak and collaborators from five other UC institutions had received a UC Multicampus Research Programs and Initiatives award in 2019 to develop a consortium working on EIC projects. That consortium was tasked with designing and building two detector systems for the EIC, with access to computing resources at Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC), and substantial contributions by students. The team just got notice that it will receive another four years of support from the UC Office of the President.

Academic aspect of job has its own rewards
Working with students as a UC professor and at Berkeley Lab has been a rewarding aspect of her work, she said. “We are the most academic of the national labs, with our close proximity to and connection with UC Berkeley. We have a lot of faculty senior scientists and a lot of postdocs, and undergrad and grad students. I have enjoyed working with students immensely.”

Prior to her time at Berkeley Lab, Jacak taught for 18 years at Stony Brook University in New York, and before that spent 12 years as a scientific staff member in Los Alamos National Laboratory’s Physics Division. A San Francisco Bay Area native, she received her bachelor’s degree in science at UC Berkeley and her doctorate at Michigan State University.

Jacak said she is encouraged by the diversity in the student population she sees coming through Berkeley Lab and campus these days. “I think it’s a real strength for us.”

A vision for the next science device
Koch should have a smooth transition into his role as acting division director, Jacak said, as he is well-known across NSD and knows Berkeley Lab well. “He’s ready to hit the ground running,” she said.

Past experience overseeing the science program at Berkeley Lab’s 88-Inch Cyclotron and running the division’s theory program gave Koch experience in management, and he said he doesn’t expect any surprises in his transition to the new role.

“I see my role in keeping things afloat and keeping things together,” Koch said, noting that Jacak’s hands-off management style was welcome to him. “She certainly didn’t micromanage us,” he said.

“I want to run this as a team,” Koch said, “and to try to get all the ideas on the table. I think that will create a productive and healthy environment for everyone.”

Koch arrived at Berkeley Lab in 1995 as a divisional fellow after obtaining undergraduate and doctoral degrees in physics from the University of Giessen in Germany, and after serving from 1990-94 as a visiting assistant professor at Stony Brook University. He was promoted to senior physicist at Berkeley Lab in 1999. Koch specializes in theories relating to heavy-ion collisions and strongly interacting matter.

He noted that Berkeley Lab has always been a breeding ground for “all kinds of accelerators” and “innovative instrumentation,” and he would like to see that legacy carried on within NSD. “Maybe we can invent the next ‘gadget’ – we can start and seed the next thing,” he said.
