New co-spokesperson begins term at DZero

Darien Wood, recent DZero co-spokesperson, poses with Stefan Soldner-Rembold, DZero's new co-spokesperson, in front of a model of the DZero detector. Soldner-Rembold will serve a two-year term as co-spokesperson.

In his three years as DZero co-spokesperson, Dmitri Denisov has gotten used to communicating with his counterpart through a window between their offices. Starting this month, he's been seeing a new face through that window.

Denisov's new neighbor is Stefan Soldner-Rembold, a DZero collaborator and physics professor at the University of Manchester. On Aug. 1, Soldner-Rembold began a two-year term as co-spokesperson of the DZero experiment. He replaces Darien Wood, who will remain on DZero while returning to teaching at Northeastern University in Boston.

After a stint as DZero's physics coordinator, Soldner-Rembold will now serve as a key communicator between the experiment and a wide web of other groups-the press, Fermilab's Directorate, other experiment groups, funding agencies and the 90 institutions that send scientists to work on DZero. Along with Denisov, he will also appoint colleagues to leadership positions within DZero and review all papers the collaboration submits for publication.

"It's like leading a small country with its laws, regulations, successes and issues," Denisov said of a spokesperson's responsibilities. But he underscored Soldner-Rembold's readiness for the job.

"The experiment is getting an extremely good spokesman in Stefan," Denisov said. "He went through many important DZero positions before this one. He became very familiar with what this position involves, particularly as physics coordinator."

Denisov also commended outgoing spokesman Darien Wood.

"Darien has the highest standards in human relations and in scientific results," Denisov said. "It's been a pleasure to work with him."

With the Tevatron's run now extended into 2011, Denisov, Wood and Solder-Rembold are enthusiastic about the discoveries DZero may make in the next few years.

"It's a fantastic opportunity to be in this position at a time when the experiment is producing so much physics," Soldner-Rembold said, explaining that DZero expects to nearly double its data set during his term as spokesperson. "The next years might be the most interesting ones for the experiment."
