Theoretical chemist Todd Martínez develops and applies new methods that predict and explain how atoms move in molecules. These methods are used both to design new molecules and to understand the behavior of those that already exist. His research group studies the response of molecules to light (photochemistry) and external force (mechanochemistry). Photochemistry is a critical part of human vision, single-molecule spectroscopy, harnessing solar energy (either to make fuels or electricity), and even organic synthesis. Mechanochemistry represents a novel scheme to promote unusual reactions and potentially to create self-healing materials that resist degradation. The underlying tools embody the full gamut of quantum mechanical effects governing molecules, from chemical bond breaking/formation to electron/proton transfer and electronic excited states.
Martínez received his PhD in chemistry from UCLA in 1994. After postdoctoral study at UCLA and the Hebrew University in Jerusalem, he joined the faculty at the University of Illinois in 1996. In 2009, he joined the faculty at Stanford, where he is now the Ehrsam and Franklin Professor of Chemistry and Professor of Photon Science at SLAC National Accelerator Laboratory. He has received numerous awards for his contributions, including a MacArthur Fellowship (commonly known as the “genius award”). He is co-editor of Annual Reviews in Physical Chemistry, associate editor of The Journal of Chemical Physics, and an elected fellow of the American Academy of Arts and Sciences.
Current research in the Martínez lab aims to make molecular modeling both predictive and routine. New approaches to interactive molecular simulation are being developed, in which users interact with a virtual-reality based molecular modeling kit that fully understands quantum mechanics. New techniques to discover heretofore unknown chemical reactions are being developed and tested, exploiting the many efficient methods that the Martínez group has introduced for solving quantum mechanical problems quickly, using a combination of physical/chemical insights and commodity videogaming hardware.

Emilio received his B.S. in Electrical Engineering and Physics from Missouri University of Science and Technology in 2007. After graduating he worked for the NASA Marshall Space Flight Center developing non-destructive evaluation techniques for applications related to the US space program. He completed his PhD in Electrical Engineering from the Massachusetts Institute of Technology in 2013 where he worked on high-frequency high-power THz sources and the development of Nuclear Magnetic Resonance spectrometers using Dynamic Nuclear Polarization. His thesis was on the first photonic-band-gap gyrotron travelling wave amplifier which demonstrated record power and gain levels in the THz frequency band.
He completed his postdoc at MIT with a joint appointment in the Nuclear Reactor Lab and the Research Laboratory for Electronics at MIT where he demonstrated the first acceleration of electrons with optically generated THz pulses. He joined the Technology Innovation Directorate at SLAC in August of 2015 where he continues his work on high power, high-frequency vacuum electron devices; optical THz amplifiers; electron-beam dynamics; and advanced accelerator concepts. His recent interests include ultrafast characterization; defect formation in semiconductors; and superconducting and solid-state devices for quantum information.”
Joshua Turner is a staff scientist at the Stanford Institute for Materials and Energy Sciences, a joint institute between Stanford University and SLAC, as well as at the Linac Coherent Light Source, the world’s first x-ray free electron laser (XFEL) based at SLAC.
He received both a BS in Physics and a BA in Mathematics from UC Santa Barbara, a MA in Physics from Boston University specializing in instrumentation constructed at the Lawrence Berkeley National Laboratory (LBNL) for magnetic spectroscopy, and a PhD in Physics from the University of Oregon. During his doctoral studies, Joshua was an Advanced Light Source Doctoral Fellow at LBNL where he built a coherent scattering endstation to study fluctuations in quantum materials. He also spent time as a visiting researcher at the Brookhaven National Laboratory where his work focused on x-ray diffraction, inelastic scattering, and nanofabrication in strongly correlated materials. He then moved to Stony Brook University, NY to work as a postdoctoral fellow, lecturer, and then adjunct assistant professor, specializing in coherent imaging to investigate biological cells and nanoporous glass.
Josh is a leader in ultra-fast x-ray studies, which he has applied to an array of scientific fields, from chemistry and materials physics to the study of plasmas found in large planets and hot astrophysical objects. His most recent focus is on an innovative technology which utilizes new modes of the XFEL and can be used to examine subtle fluctuations in materials using short, coherent x-ray pulses. This will advance the frontier in quantum materials through the observation of novel types of order found in exotic systems such as topological magnets, unconventional superconductors, and strongly spin-orbit coupled Mott insulators. He is the recipient of the Department of Energy’s Early Career Award, a prestigious award granted to further the individual research programs of outstanding scientists with demonstrated successful research activities and potential for solving important problems to the U. S. government. He has published over 100 scientific articles with one-third of them in high-profile journals.
