by the Republic of France. Among his groups' principal achievements at Bell were observation of quenching of the Hall effect in a quasi-one-dimensional wire, elucidation of electron-boundary scattering in quantum wires, invention of "anti"-dots and elucidation of commensurability effects in this system, first elucidation of chaotic transport in mesoscopic conductor, and direct measurement of the transmission matrix for a mesoscopic conductor. Among his groups' principal achievements at Caltech are development of the first nanoelectromechanical systems, measurement of the quantum of thermal conductance, first attainment of attogram mass resolution with a NEMS resonator, first measurement of nanodevice motion at microwave frequencies, discovery of the giant planar Hall effect in semiconducting ferromagnets, observation and control of a single domain wall in a ferromagnetic semiconducting wire, first demonstration of zeptogram-scale mass sensing, first coupling of a qubit to a NEMS resonator, and first demonstration of nanomechanical mass spectrometry of single protein molecules. Roukes has authored or co-authored highly cited general interest articles on nanophysics, nanoelectromechanical systems, spintronics, and quantum electromechanics. Roukes and his collaborators have been issued 57 patents in his fields of research. An electron micrograph of the quantum of thermal conductance device, taken by postdoc Keith Schwab and colorized by Roukes, was acquired for the permanent collection of the Museum of Modern Art in 2008. Roukes organized TEDxCaltech: Feynman's Vision - The Next 50 Years, held on January 14, 2011, which celebrated the genius of Caltech physicist Richard Feynman in a series of forward-looking talks in the TED (conference) format. Subsequently, he organized TEDxCaltech: The Brain, which was held on January 19, 2013 at Caltech. Talks from these events can be found online. In 2002, with three other scientists, Roukes met with, Elias Zerhouni, the Director of the U.S. National Institutes of Health, and the Directors of the National Cancer Institute, the National Institute of Neurological Disorders and Stroke, and several other NIH directors to propose what ultimately became the National Cancer Institute's Alliance for Nanotechnology in Cancer. In 2011, Roukes was one of the six scientists first advocating, to the White House Office of Science and Technology Policy (OSTP), a large-scale U.S. national neuroscience project to accelerate technology for functional connectomics. The group's concept of a Brain Activity Map project ultimately led to President Obama's BRAIN Initiative, launched in 2013. In 2016, Roukes founded the multi-institution Neurotech Alliance to disseminate state-of-the-art neurotechnology to the neuroscience research community. External links The
