Nergis Mavalvala(born 1968) is a Pakistani-Parsi-Americanastrophysicist.She is the Curtis and Kathleen Marble Professor ofAstrophysicsat theMassachusetts Institute of Technology(MIT), where she is also the dean of the university'sschool of science.She was previously the Associate Head of the university'sDepartment of Physics.[1]Mavalvala is best known for her work on the detection of gravitational waves in theLaser Interferometer Gravitational-Wave Observatory(LIGO) project,[1][2]and for the exploration and experimental demonstration ofmacroscopicquantumeffects such assqueezinginoptomechanics.She was awarded aMacArthur Fellowshipin 2010.[3][4][5]

Early life and education

[edit]

Mavalvala was born inLahore,but primarily raised inKarachi,Pakistan.[6]She attended theConvent of Jesus and Mary,Karachi,where she received herO-LevelandA-Levelqualifications. She moved to the United States in 1986 and enrolled atWellesley College,where she received abachelor's degreein physics andastronomyin 1990. She then joinedRainer Weiss's group in the MIT physics department and received herPhDin 1997. Born to aParsifamily that practicedZoroastrianism,Mavalvala was the younger of the two children.[2][7]

Career

[edit]

As a graduate student at MIT, she conducted her doctoral work underRainer Weiss,where Mavalvala developed a prototype laser interferometer for detecting gravitational waves.[8]After graduate school, she worked as apostdoctoral researcherand then as a research scientist at theCalifornia Institute of Technology,starting her work withcosmic microwave background,[9]and then eventually working on the LIGO.[10]Mavalvala focuses primarily on two fields of physics:Gravitational Waves Astrophysicsand quantum measurement science.[11]Mavalvala joined the MIT physics faculty in 2002.[10]In 2017 she was elected to theNational Academy of Sciences.[12]

Detection of gravitational waves

[edit]

Mavalvala was among the team of scientists who, for the first time, observed ripples in the fabric ofspacetimecalledgravitational waves.Mavalvala has been working on gravitational waves since 1991.[11]After the announcement of the observation, she became an instant celebrity scientist in her birthplace of Pakistan. A statement by thePrime Minister of PakistanNawaz Sharifpraised Mavalvala, calling her a source of inspiration for Pakistani scientists and students aspiring to become future scientists. He also stated that"the entire nation is proud of her valuable contribution."[13]

On 20 February 2016,Ambassador of Pakistan to the United States,Jalil Abbas Jilani,conveyed theGovernment of Pakistan's message of felicitation to Mavalvala for her outstanding achievement in the field of astrophysics. He also invited her to re-visit Pakistan, which she accepted.[14][15][16][17]

Laser cooling

[edit]

Optical cooling of mirrors to nearlyabsolute zerocan help eliminatemeasurement noisearising from thermal vibrations. A portion of Mavalvala's work focused on the extension of laser-cooling techniques to optically cool and trap more and moremassiveobjects, both for the LIGO project and for other applications, such as to enable observation ofquantum phenomena in macroscopic objects.Prominent results from her group in this area included the cooling of acentimeter-scale object to a temperature of 0.8kelvinand the observation of a 2.7-kilogrampendulumnear its quantumground state.These experiments lay the foundations for observing quantum behavior in human-scale objects.[18][19]

Quantum states of light

[edit]

Mavalvala has also worked on the development of exotic quantum states oflight,and in particular the generation of light in squeezed coherent states.[20][21]By injecting such states into the kilometre-scaleMichelson interferometerof the LIGO detectors, her group greatly improved the sensitivity of the detector by reducing quantum noise;[21]such squeezed states also have many other applications in experimental physics.[22]Her group was the first to generate squeezed light using optomechanics at room temperature,[23][24]compared to all previous optomechanical squeezed light sources that operated atcryogenic(very low) temperatures.

Personal life

[edit]

Mavalvala identifies as alesbianand speaks openly on her sexual orientation and family history as a Pakistani immigrant, describing herself as an "out, queer person of color."[25]Mavalvala stated that she was not aware of her sexual orientation until after college. Mavalvala is frequently questioned about how she was able to break through the barrier ofgender rolesand pursue a career of her choice. In an interview with the Pakistani newspaperDawn,Mavalvala states, "I grew up in a family where the stereotypical gender roles were not really observed. So I grew up thinking women can, must and should do anything and everything. That is very important for me."[7]She also speaks about the ability of individuals in Pakistan to break gender roles and stigmas: "Anybody should be able to do those things. And I am proof of that because I am all of those things. With the right combination of opportunity, it was possible for me to do."[25]

Mavalvala is often viewed as a role model for aspiring female scientists with roots in theIndian subcontinent.As a young child Mavalvala was frequently involved in handy work, and was not bound to stereotypical gender roles in subcontinent culture, due to the manner in which her sister and she were raised. Mavalvala states that much of her success is accredited to good mentors in both the United States and Pakistan that encouraged her academic ability. In a television interview in 2016, Mavalvala stated, "When everyone has access to education that's when all the other things come into place... [You've] got to do what gives you pleasure, gotta find a way to do it. People should just do what they enjoy most and I think for all of society whether it's in Pakistan or elsewhere we have to create opportunities for young girls to do what they're good at and do what they love to do must cultivate the sense of wonder in a child."[26]

Mavalvala and her partner have two children and reside inCambridge, Massachusettsin the United States. Mavalvala has extended family in Karachi and visited the city in 2010.[10][14][27][28][29]
