Education
Roukes earned
B.A. degrees in physics and chemistry (double majors) in 1978 at
University of California, Santa Cruz, with highest honors in both majors, he received his
Ph.D. in physics from
Cornell University in 1985. His graduate advisor at Cornell was Nobel Laureate,
Robert Coleman Richardson.
Roukes’ thesis research at Cornell elucidated the electron-

In physics, a phonon is a collective excitation in a periodic, Elasticity (physics), elastic arrangement of atoms or molecules in condensed matter physics, condensed matter, specifically in solids and some liquids. A type of quasiparticle, a phon ...
bottleneck at ultra low temperatures; the
hot electron effect that is now recapitulated in texts on solid state transport physics. Stated in simplest terms, when electrons carry current in normal conductors, they heat up. At low temperatures and, now, in nanoscale devices at ordinary temperatures, their ability to dissipate this heat can be significantly impaired. This has generic implications for the operation of powered nanodevices.
Research and academic career
After earning his Ph.D., Roukes spent seven years as a member of technical staff / principal investigator in the Quantum Structures Research group at Bell Communications Research in New Jersey, focusing on
mesoscopic physics of electron transport in nanostructures. Roukes left Bellcore to become a tenured associate professor of physics at Caltech in 1992, rising to full professorship in 1995, and subsequently became professor of physics, applied physics, and bioengineering in 2000. Upon moving to Caltech, his principal research focus changed to
nanoelectromechanical systems (NEMS). As the earliest pioneer in this field,
DARPA engaged Roukes to organize the first international workshop on NEMS in 1999, followed by a large international conference and school on nanoscale and molecular mechanics in 2002. The many alumni from his group continue to advance this field at major universities in the U.S. and abroad. Roukes' other research efforts at Caltech have focused on
thermal properties of nanostructures, semiconductor
spintronics, and, more recently,
nanobiotechnology
Nanobiotechnology, bionanotechnology, and nanobiology are terms that refer to the intersection of nanotechnology and biology. Given that the subject is one that has only emerged very recently, bionanotechnology and nanobiotechnology serve as blan ...

In 2002 Roukes was named the founding director of the ''Kavli Nanoscience Institute'' (KNI) at Caltech. After stepping down between 2006–2008, to focus on co-founding the international ''Alliance for Nanosystems VLSI'' (very large scale integration) and to pursue collaborative research on NEMS VLSI in connection with a ''Chaire d’Excellence'' in Nanoscience in Grenoble (with scientists at

Minatec), Roukes returned as co-Director of the KNI in 2008.
Roukes was named a recipient of a
National Institutes of Health Director's Pioneer Award in 2010. In 2012 he was named Chevalier (Knight) of the
Ordre des Palmes Académiques 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.
Events, affiliations and campaigning
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

(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.
