Ken R. Ferguson, Ph.D.
Vehicle Engineering

Dr. Ken R. Ferguson is a Scientist at Exponent’s Test and Engineering Center in the Vehicle practice. Dr. Ferguson has diverse scientific experience with expertise in experimental design, instrumentation, data acquisition, and analysis.

Prior to joining Exponent, Dr. Ferguson was a member of the Atomic, Molecular, and Optical Sciences group at the Linac Coherent Light Source at SLAC National Accelerator Laboratory. While there, he worked on a wide variety of projects pertaining to x-ray science. Dr. Ferguson has scientific expertise in serial femtosecond x-ray crystallography, x-ray coherent diffractive imaging, and ion/electron spectroscopy. He has been an integral part in the development and commissioning of many experimental technologies, including pump—probe temporal delay measurements, x-ray split-and-delay components, velocity map imaging, and coherent diffractive imaging capabilities. At SLAC Dr. Ferguson contributed to the design and development of various experimental environments, spectrometers, and diagnostic tools, often combining off-the-shelf components with custom designed elements.

Dr. Ferguson received his Ph.D. in Applied Physics from Stanford University in 2016. His dissertation work focused on the ultra-fast interaction of atoms, molecules, and complex nanoparticles with high-intensity, femtosecond x-ray pulses from a free electron laser.
