    Blewett Scholarship Winners Announced

    By Michael Lucibella

    The American Physical Society awarded five M. Hildred Blewett
    scholarships this year to women returning to their careers after a
    hiatus, the largest number of winners since the beginning of the
    program.

    Chosen by the APS Committee on the Status of Women in Physics, the
    five include three new recipients and two returning recipients from
    last year. Amy Daradich of the University of Ottawa and Leslie Kerby
    at Los Alamos National Laboratory first received scholarships in 2013,
    while Ani Tshantshapanyan of North Carolina Central University,
    Monique Tirion of Clarkson University, and Lusaka Bhattacharya of
    Oklahoma State University are new.

    The scholarship is a one-year grant of up to $45,000 that can be used
    towards a wide range of necessities, including equipment procurement,
    salary, travel, tuition, and dependent care. This is the tenth year
    the scholarship has been awarded.

    Ani Tshantshapanyan was first drawn to physics during high school in
    Armenia. "My parents are chemists, they're also PhDs," she said. "I
    grew up in that environment of science."

    She received her PhD in semiconductor physics from the Yerevan State
    University. At the same time, she had also been working as a
    laboratory assistant and then as a senior lecturer at the department
    of applied physics at the Russian-Armenian University, also in
    Yerevan, Armenia.

    Then in 2012 her husband Karen, who also has a doctorate in physics,
    took a job in Durham, North Carolina. "We moved to a different country
    and finding a secure job was not easy," Tshantshapanyan said.

    After her third child was born last June, Tshantshapanyan decided to
    step away from research for a short while to spend more time raising
    her three children. "After about one year I started to search for a
    position," Tshantshapanyan said.

    Through her husband, she found a postdoc position at North Carolina
    State University studying the complex geometry of quantum dots, which
    have been used in detectors and lasers.

    "My research is about the physical properties of so-called quantum
    dots," she said.

    "Properties of quantum dots can be controlled by their external shape
    and many other physical properties."

    With the help of the Blewett fellowship, she hopes to publish more
    papers on her research, as well as develop software to further her
    work. She hopes also to establish contacts with other research
    institutions nearby and ultimately find a private company to
    collaborate with in order to commercialize the kind of quantum dots
    she's been helping to develop.

    Monique Tirion is returning to physics in order to work on better
    understanding the dynamics of proteins. X-ray crystallography is a
    well-established method for studying the makeup of proteins that make
    life possible. However, it turns out that scientists have been seeing
    only part of the story. "So people have been admiring these static
    images for a long time," Tirion said. "We can take it a step
    further... We can make those static images [into] dynamic images."

    Using software she has been helping to develop, she has been able to
    calculate the normal vibrational modes of the different proteins based
    on their shapes. The work has helped explain some of the finer points
    of how these protein systems behave. "It's not an easy computation,
    but if you carry it through, the insights you gain from it can be very
    exciting," Tirion said. "The static images really can't elucidate how
    all of these little mysteries are resolved."

    She said she's always been driven by her fascination with the
    biological sciences and trying to understand how the world works and
    what makes things happen. "It's just a natural evolution," Tirion
    said. "The world around us is so astounding, the trees and the flowers
    and whatnot. My effort to understand that naturally came to this
    scale, nanoscale where I'm working."

    Tirion attended Texas A&M University for her undergraduate degree in
    physics, and then Boston University for her PhD. There she met Daniel
    Ben-Avraham, her future husband. Shortly after receiving her
    doctorate, her husband took a job at Clarkson University in upstate
    New York. The two moved to the small town of Potsdam, and a short time
    later her son Yoel was born.

    Yoel was born with three health issues. "All three individually take
    some effort to supervise, but all three at the same time was a bit
    overwhelming, so I decided to give it my full attention."

    She carefully monitored his diet and homeschooled Yoel until he
    started the 7th grade, and today he is much healthier. With Yoel doing
    well, Tirion has been able to return to research. Thanks to the
    Blewett support, she hopes to take the recent work she's been doing on
    proteins even further.

    "I would like to make it more easily available to the
    crystallographers," Tirion said. "I'm not sure where it will go, but
    I'm just analyzing these systems and sharing them with the
    crystallographers, and seeing where it takes me."

    Lusaka Bhattacharya grew up in India and had always been interested in
    the sciences. "Physics is very interesting to me because in physics
    you have mathematics, a theoretical part, and you have an experimental
    part," Bhattacharya said. "My mom is also a mathematician so I decided
    that that means I would study physics."

    She studied theoretical nuclear physics at the Saha Institute of
    Nuclear Physics in India and received her PhD from the University of
    Calcutta in 2012. Studying nuclear physics there, she focused on
    studying the quark-gluon plasma, and traveled a great deal to present
    her work around the world. "It is a very new field so you can explore
    a lot," Bhattacharya said. She added that the idea of learning about
    what made up the universe just an instant after the Big Bang was what
    attracted her to the field.

    While working on her doctorate, she met her husband, and the two
    married in 2010. He finished his degree early and traveled first to
    Helsinki, and then to Oklahoma, for his postdoc work. After
    Bhattacharya finished her doctorate in 2012, she moved to Oklahoma to
    join her husband. "My husband is a theoretical physicist like me, but
    it is very difficult to get a postdoctoral position in the same
    university," she said.

    It was the first time the two had been able to live in the same city
    for an extended period of time. Bhattacharya decided to take some time
    away from research and start a family. Earlier this year, her first
    child was born. "Now he's almost nine months old so now I think I
    should start my career again," she said.

    She started volunteering at Oklahoma State University and
    collaborating with her mentor at Kent State University. She's helping
    to develop a photon probe for detecting when particle collisions have
    created a quark-gluon plasma.
