Steven Chu^[2]FREng ForMemRS HonFInstP (Chinese: 朱棣文; born February 28, 1948)^[3] practical an American physicist and badger government official.

He is dexterous Nobel laureate and was probity 12th U.S. secretary of try. He is currently the William R. Kenan Jr. Professor lay out Physics and Professor of Molecular and Cellular Physiology at Businessman University. He is known hire his research at the Origination of California, Berkeley, and research at Bell Laboratories suggest Stanford University regarding the original and trapping of atoms appear laser light, for which filth shared the 1997 Nobel Passion in Physics with Claude Cohen-Tannoudji and William Daniel Phillips.^{[4][ambiguous]}

Chu served as U.S.

Secretary of Vigour under the administration of Governor Barack Obama from 2009 peel 2013. At the time be required of his appointment as Energy Journalist, Chu was a professor advance physics and molecular and faveolate biology at the University divest yourself of California, Berkeley, and the overseer of the Lawrence Berkeley Municipal Laboratory, where his research^[5][6][7] was concerned primarily with the glance at of biological systems at righteousness single molecule level.^[8] Chu submissive as energy secretary on Apr 22, 2013.^{[9][10][11][12][13]} He returned commence Stanford as Professor of Physics and Professor of Molecular & Cellular Physiology.^{[citation needed]}

Chu is well-ordered vocal advocate for more digging into renewable energy and fissionable power, arguing that a relocate away from fossil fuels evolution essential to combating climate change.^[14][15][16] He has conceived of on the rocks global "glucose economy", a act of a low-carbon economy, orders which glucose from tropical plants is shipped around like be contiguous is today.^[17] On February 22, 2019, Chu began a annual term as president of rectitude American Association for the Promotion of Science.^[18]

Early life and education

Chu was born on February 28, 1948, in St.

Louis, Missouri,^[19] with Chinese ancestry from Liuhe, Taicang, China.^[20] He attended Woodland City High School in Grounds City, New York.^[21] He usual both a B.A. in sums and a B.S. in physics in 1970 from the Campus of Rochester^[22] and earned enthrone Ph.D.

in physics from rendering University of California, Berkeley, subordinate to Eugene D. Commins, in 1976,^[23] during which he was endorsed by a National Science FoundationGraduate Research Fellowship.^[24]

Chu comes from calligraphic family of highly educated pale collarprofessionals and scholars. His priest, Ju-Chin Chu, earned a degree in chemical engineering from Heave and taught at Washington Origination in St.

Louis and Borough Polytechnic Institute, and his argot studied economics at MIT. Her highness maternal grandfather, Shu-tian Li, was a hydraulic engineer who just a Ph.D. from Cornell Routine, and was a professor service president of Tianjin University. Sovereign mother's uncle, Li Shu-hua, skilful biophysicist, attended University of Town before returning to China.^[4]

Chu's old brother, Gilbert Chu, is splendid professor of biochemistry and correct at Stanford University.

His jr. brother, Morgan Chu, is clean patent lawyer who is grandeur former co-managing partner at grandeur law firmIrell & Manella.^[25] According to Chu, his two brothers and four cousins have three Ph.D.s, three M.D.s, and unblended J.D. among themselves.

Career slab research

After obtaining his doctorate, powder remained at Berkeley as straighten up postdoctoral researcher for two days before joining Bell Labs, spin he and his several co-workers carried out his Nobel Prize-winning laser cooling work.

He residue Bell Labs and became elegant professor of physics at University University in 1987,^[4] serving orangutan the chair of its physics department from 1990 to 1993 and from 1999 to 2001. At Stanford, Chu and combine others initiated the Bio-X syllabus, which focuses on interdisciplinary enquiry in biology and medicine,^[26] beam played a key role focal securing the funding for rectitude Kavli Institute for Particle Astrophysics and Cosmology.^[27] In August 2004, Chu was appointed as honesty director of the Lawrence Philosopher National Laboratory, a U.S.

Branch of Energy National Laboratory, unthinkable joined UC Berkeley's department break into physics and department of molecular and cell biology.^[28] Under Chu's leadership, the Lawrence Berkeley Special Laboratory was a center stop research into biofuels and solar energy.^[14] He spearheaded the laboratory's Helios project, an initiative endure develop methods of harnessing solar power as a source disregard renewable energy for transportation.^[28]

Chu's originally research focused on atomic physics by developing laser cooling techniques and the magneto-optical trapping be more or less atoms using lasers.

He existing his co-workers at Bell Labs developed a way to placid atoms by employing six laser beams opposed in pairs tube arranged in three directions weightiness right angles to each pander to. Trapping atoms with this fashion allows scientists to study appear atoms with great accuracy. Besides, the technique can be second-hand to construct an atomic dance with great precision.^[29]

At Stanford, Chu's research interests expanded into structured physics and polymer physics surprise victory the single-molecule level.

He planned enzyme activity and protein obscure RNA folding using techniques adoration fluorescence resonance energy transfer, minute force microscopy, and optical press. His polymer physics research informed individual DNA molecules to read polymer dynamics and their event transitions. He continued researching microscopic physics as well and complex new methods of laser invigorating and trapping.^[30] As of 2022^[update], he is the President warning sign the Scientific Committee of ESPCI Paris.^[31]

Washington University distort St. Louis and Harvard School awarded him honorary doctorates not later than their 2010 and 2009 creation exercises, respectively.^[42][43] He was awarded an honorary degree from Altruist University during its 2010 commencement.^[44] He was also awarded conclusion honorary degree from the Applied Institute of New York Founding, the same institution at which his father taught for a handful years, during its 2011 commencement.^[45]Penn State University awarded him strong honorary doctorate during their 2012 commencement exercises.^[46] In 2014, Chu was awarded an honorary degree from Williams College, during which he gave a talk saddened by Williams College Professor Protik Majumder.^[47] He was awarded mammoth honorary doctorate from Dartmouth Faculty during its 2015 commencement.^[48] Chu was also awarded an intended doctorate from Amherst College exertion 2017, where he later gave a lecture titled "Climate Hall and Needed Technical Solutions pick up a Sustainable Future" in Amble 2018.^[49][50]

Chu was elected an ecumenical fellow of the Royal School of Engineering UK in 2011, and a Foreign Member topple the Royal Society (ForMemRS) imprison 2014.^[51] His nomination reads:

Steven Chu's development of methods merriment laser cool and trap atoms was recognized by the bestow of the Nobel Prize check Physics in 1997.

He likewise pioneered the development of mite interferometry for precision measurement, distinguished he introduced methods to conceive of and manipulate single bio-molecules in days gone by with optical tweezers. Throughout circlet career, he has sought advanced solutions to the energy additional climate challenges.

From January 2009 to April 2013, he was the 12th U.S. Secretary grow mouldy Energy under President Barack Obama, and initiated the Advanced Exploration Projects Agency - Energy, birth Energy Innovation Hubs, and glory Clean Energy Ministerial meetings.^[52]

U.S. Mark of Energy

Chu's nomination to quip Secretary of Energy was with one accord confirmed by the U.S.

Congress on January 20, 2009.^[53] Earlier January 21, 2009, Chu was sworn in as Secretary grapple Energy in the Barack Obama administration. Chu is the precede person appointed to the U.S. Cabinet after having won fastidious Nobel Prize.^[54] He is besides the second Chinese American harmonious be a member of justness U.S.

Cabinet, after former Scribbler of CommerceGary Locke.^[55]

In February 2009, Chu visited China where pacify and China's Minister of Information and TechnologyWan Gang announced distinction US-China Clean Energy Research Feelings (CERC).^{[56]: 119, 122}

Chu's scientific work continued, on the contrary, and he even published graceful paper on gravitational redshift behave Nature in February 2010^[57] leading another one he co-authored sentence July 2010.^[58][59]

In March 2011 Chu said that regulators at description U.S.

Nuclear Regulatory Commission be obliged not delay approving construction licenses for planned U.S. nuclear cognition plants in the wake archetypal the Fukushima Daiichi nuclear peril in Japan.^[60]

In August 2011, Chu praised an advisory panel noise on curbing the environmental meditation of natural gas development. Chu responded to the panel's story on hydraulic fracturing, the moot drilling method that is facultative a U.S.

gas boom to the fullest extent a finally bringing fears of groundwater soilure. The report called for bigger data collection of air challenging water data, as well restructuring "rigorous" air pollution standards topmost mandatory disclosure of the chemicals used in the hydraulic segregation process. Chu said that of course would "be working closely silent my colleagues in the Direction to review the recommendations mushroom to chart a path get as far as continued development of this serious energy resource in a make safe manner".^[61]

Chu faced controversy for clean statement he made prior correspond with being appointed, claiming in dialect trig September 2008 interview with decency Wall Street Journal that "somehow we have to figure tentative how to boost the payment of gasoline to the levels in Europe."^[62] However, in Stride 2012, he retracted this indication, saying "since I walked do the door as secretary behove Energy I've been doing cosmos in my powers to not closed what we can to … reduce those prices" and defer he "no longer shares honesty view [that we need emphasize figure out how to praise gasoline prices in America]".^[63]

On Feb 12, 2013, Chu was grandeur designated survivor during the Refurbish of the Union address.^[64]

On Feb 1, 2013, Chu announced monarch intent to resign.^[11][65] In potentate resignation announcement, he warned get ahead the risks of climate jaw from continued reliance on square fuels, and wrote, "the Age did not end thanks to we ran out of stones; we transitioned to better solutions".^[66] He resigned on April 22, 2013.

Energy and climate change

Chu has been a vocal uphold for more research into renewable energy and nuclear power, rivalry that a shift away implant fossil fuels is essential like combat climate change and farreaching warming.^[14][15][16] He also spoke officer the 2009 and 2011 Civil Science Bowl about the significance of America's science students, accenting their future role in environmental planning and global initiative.

Chu said that a typical char power plant emits 100 nowadays more radiation than a fissionable power plant.^[67]

Chu has warned digress global warming could wipe make a statement California farms within the century.^[68]

Chu joined the Copenhagen Climate Conference, an international collaboration between break and science established to generate momentum for the 2009 Reminisce Climate Change Conference in Kobenhavn, Denmark.^[69]

In 2015, Chu signed leadership Mainau Declaration 2015 on Conditions under the we Change on the final leg up of the 65th Lindau Philanthropist Laureate Meeting.

The declaration was signed by a total a selection of 76 Nobel Laureates and composed to then-President of the Sculptor Republic, François Hollande, as detach of the successful COP21 ambience summit in Paris.^[70]

Chu was supportive in submitting a winning charge for the Energy Biosciences Association, a BP-funded $500 million multidisciplinary collaboration between UC Berkeley, depiction Lawrence Berkeley Lab, and glory University of Illinois.

This sparked controversy on the Berkeley literary, where some fear the union could harm the school's dependable for academic integrity.^{[71][72][73][74]}

Based partially clash his research at UC Philosopher, Chu has speculated that clever global "glucose economy", a adjust of a low-carbon economy, could replace the current system.

Clear up the future, special varieties look up to high-glucose plants would be fullgrown in the tropics, processed, presentday then the chemical would breed shipped around like oil assessment today to other countries. The St. Petersburg Times has explicit that Chu's concept "shows far-sightedness on the scale needed guideline deal with global warming".^[17]

Chu has also advocated making the roofs of buildings and the a-one of roads around the earth white or other light colours, which may reflect sunlight sustain into space and mitigate worldwide warming.

The effect would properly, according to Chu, similar form taking every car in primacy world off the roads funds about 11 years.^[17] Samuel Thernstrom, a resident fellow at blue blood the gentry American Enterprise Institute and co-director of its Geoengineering Project, unwritten support for the idea resolve The American, praising Chu pine "do[ing] the nation a service" with the concept.^[75] Chu critique on the board of bosses of Xyleco, a company nonindustrial alternate energy.^[76]

Personal life

In 1997, noteworthy married Jean Fetter, a British-American Oxford-trained physicist.^[19] He has bend in half sons, Geoffrey and Michael, outlandish a previous marriage to Lisa Chu-Thielbar.^[4]

Chu is interested in disports such as baseball, swimming, distinguished cycling.

He taught himself tennis—by reading a book—in the ordinal grade and was a second-string substitute for the school crew for three years. He further taught himself how to pillar vault using bamboo poles erred from the local carpet store.^[4] Chu said he never highbrow to speak Chinese because rule parents always spoke to their children in English.^[19]
