The California laboratory’s principal programs include nuclear weapons stewardship; homeland security with a focus on defending against weapons of mass destruction; combustion, transportation and hydrogen energy research; biology; and advanced computational and information systems.

Prior to moving to Sandia’s California laboratory, Rottler guided corporate research and development efforts as chief technology officer and vice president of Science and Technology. He also managed technology transfer and strategic research relationships with universities, industry, and the state of New Mexico.

Rottler has also held a number of leadership roles within Sandia’s Nuclear Weapons mission, including, most recently, chief engineer for nuclear weapons and vice president, Weapon Engineering and Product Realization where he was the central technical authority for nuclear weapons and led all nuclear weapon engineering and production activities at Sandia. He has been responsible for nuclear warhead system engineering and integration, development of high-performance electronic systems, and system analyses and assessments for Sandia and National Nuclear Security Administration senior management. He also managed organizations and programs responsible for the research, development, and application of advanced computational and experimental techniques in the engineering sciences. As a member of technical staff at Sandia, Rottler was part of a research team that developed multidimensional radiation-hydrodynamics simulation codes for nuclear weapon applications, and he led projects that supported the development of advanced nuclear and conventional weapon concepts.

Rottler is a fellow of the American Institute of Aeronautics and Astronautics, a member of the Institute’s board of directors, and a past chair of the Institute’s Technical Committee on Management.
