SLAC Director Chi-­Chang Kao, a noted X-ray scientist, came to SLAC in 2010 to serve as associate laboratory director for the Stanford Synchrotron Radiation Lightsource. He became SLAC’s fifth director in November 2012.

Previously, Kao served for five years as chairperson of the National Synchrotron Light Source at Brookhaven National Laboratory in New York. He undertook major upgrades to the light source's scientific programs and experimental facilities while developing potential science programs for NSLS-­II, one of the newest and most advanced synchrotron facilities in the world. His research focuses on X-­ray physics, superconductivity, magnetic materials and the properties of materials under high pressure.

Kao earned a bachelor's degree in chemical engineering in 1980 from National Taiwan University and a doctorate in chemical engineering from Cornell University in 1988. He joined Brookhaven shortly afterward, working his way from NSLS postdoctoral research assistant to chair. Kao also served as an adjunct professor in the Department of Physics and Astronomy at Stony Brook University.

He was elected a fellow of the American Physical Society in 2006 and was named a fellow of the American Association for the Advancement of Science in 2010 for his many contributions to resonant elastic and inelastic X-­ray scattering techniques and their application to materials physics, as well as for his leadership at the NSLS.

As the interim deputy director for operations at SLAC, Marc Clay is responsible for ensuring the effective integration and performance of operations functions that support the lab’s growing scientific mission. As SLAC’s interim chief operating officer, he oversees the lab’s Business & Technology Services, Facilities & Operations, Human Resources, Communications and Environment, Safety & Health divisions. Previous to these roles, he was the director of the Office of Contractor Assurance and Contract Management at SLAC, responsible for providing leadership, management and strategic planning for all aspects of mission assurance and implementing the SLAC Revolutionary Working Group model contract.

Before joining SLAC, Marc was the Director of the Office of Mission Assurance and Prime Contract at Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico.  Marc was a member of the Laboratory’s Operations Team and providing direction for executing all aspects of mission assurance, including the implementation of the Laboratory’s Contractor Assurance System (CAS) and prime contract.

Marc worked for a large part of his career at LANL, including being a member of the management team for the Laboratory’s Nuclear and High Hazard Operations organization and provided oversight for various aspects of nuclear facility operations.  Marc also served in several management positions at LANL in Quality and Performance Assurance (QPA) and Dynamic Experimentation (DX).  While in DX, Marc enabled and supported large scale experiments and operations for DX Division through implementation of programs for high explosive safety, safety basis, ES&H, radiological protection, facilities and infrastructure, safeguards and security, and conduct of operations.  Marc also worked for many years in particle accelerator operations for the Los Alamos Meson Physics Facility (now known as the Los Alamos Neutron Scattering Center (LANSCE)).  Marc was a principal contributor to the reliable, efficient, and safe operation of the proton accelerator and beam delivery complex.

Marc also served in the United States Navy for six years.  While in the Navy, Marc was the leading petty officer of the Nuclear Electrical Division aboard the nuclear-powered guided missile cruiser USS Long Beach, CGN-9.  Marc was the supervisor in the operation and maintenance of all electrical systems associated with the ship’s #2 nuclear power plant. Marc received an A.S. degree from the University of New Mexico, a B.S. degree from Regents College, and an M.S. degree from Duke University.
