With about 400 employees and an annual budget of $140 million, C-AD develops, improves and operates a suite of accelerators used for experiments by an international community of about 1,500 scientists. The department also designs and constructs new accelerators in support of the Laboratory’s and national missions.

Roser earned a Ph.D. in physics from the Swiss Federal Institute of Technology in Zurich in 1984. He became a research fellow at the University of Michigan in the same year and was appointed assistant professor of physics at the university in 1990. He joined Brookhaven Lab as an associate physicist in 1991, and, in 1994, he became the head of the Accelerator Division for Brookhaven’s Alternating Gradient Synchrotron Department, which later became C-AD. In 1999, he was promoted to senior physicist with tenure, and he became the accelerator division head at C-AD, in charge of commissioning RHIC. In addition, he was appointed associate chair for accelerators in 2002.

Roser is a fellow of the American Association for the Advancement of Science, the American Physical Society, and the IEEE. He has been honored with Brookhaven Lab’s Sambamurti Memorial Lectureship Award in 1994, the BNL Science and Technology Award in 2000, and the Nuclear & Plasma Sciences Society/IEEE Particle Accelerator Science and Technology Award in 2005. He has served on numerous advisory committees, and he is currently chair of both the CERN Machine Advisory Committee and the Organizing Committee of the Particle Accelerator Conferences.
