    Boppart is director of the Biophotonics Imaging Laboratory at

the development of non-invasive or minimally invasive methods for
generating high-resolution, real-time images of biological tissue at the
cellular and molecular level for disease diagnosis at earlier stages and
in greater detail than current methods.
    A focus for Boppart is diagnosis of breast cancer through the use
of an imaging technique called optical coherence tomography (OCT)
that provides micron-scale images of subsurface biological tissue. In
the OCT-based system Boppart’s lab developed, a beam of near-in-
frared light is focused on the tissue and the resulting reflections are
measured by their intensity and position to provide a high-resolution
image in real time. While the possible applications of this technology
are many, the potential of using the OCT system for what are called             In his video interview, Boppart talks about the advantages the

    Michael Insana is not only heads the Bioimaging Science and
Technology group at Beckman but also a leader in developing novel
ultrasonic instrumentation and methods for biological imaging. In-
sana is part of a Beckman seed proposal with four other Institute
collaborators – Thomas Huang, Zhi-Pei Liang, Stephen Boppart, and
Rohit Bhargava – for developing molecular scale imaging technolo-
gies for imaging breast cancer.
    Insana, interim head of the Bioengineering Department at Illi-
nois, is interested in biomedical imaging and biological modeling
and instrumentation. His research focuses on “the development of
novel ultrasonic instrumentation and methods for imaging soft tis-
sue microstructure, elasticity and blood flow” toward understanding
the “basic mechanisms of lesion formation, disease progression, and
responses to therapy.”
    One project of Insana’s lab is development of applications for im-

allow noninvasive visualization of soft tissue stiffness. A current proj-

    William O’Brien, Director of the Bioacoustics Research Labora-
tory at the Beckman Institute, is pushing ultrasound imaging meth-
ods in new directions, including the development of an innovative
method for breast cancer screening.
    O’Brien’s research involves ultrasound-tissue interactions, includ-
ing a major effort to understand and develop quantitative ultrasound
imaging (QUS) approaches.
    The work is dedicated to real world solutions as O’Brien and his
collaborators seek to advance ultrasound technology for medical ap-
plications, including developing QUS technology as a reliable, fast,
and inexpensive method that has advantages over conventional quali-
tative medical ultrasound for diagnosing disease. They write that QUS
imaging “relies heavily on signal processing techniques to extract in-
formation about underlying tissue microstructure” and that to fully
exploit its potential, digital signal processing methods are needed.
    While working to improve the technique, O’Brien and his col-
laborators have already applied QUS to detect and diagnosis both
malignant tumors and non-cancerous ones such as a mammary tu-
mor called fibroadenoma, an important innovation for breast cancer
screening.                                                                    In his video interview, O’Brien explains the advantages, such

    Rohit Bhargava’s research is focused on developing chemical imag-
ing methods for medical and research applications. His truly innova-
tive work is leading to new imaging techniques that provide for better
diagnosis of human cancers.
     Bhargava’s work contributes a chemical information component
to the field of bioimaging. By developing these methods, Bhargava
says that researchers and technicians are able to look at how both

    While the original chemical imaging methods were created else-
where, Bhargava’s work has taken the technology to a new level, creat-
ing techniques that allow imaging in a matter of seconds as opposed
to older methods requiring several days. Bhargava said the method is
valuable for evaluating the technology for diagnosing cancer, for use
as an analytical tool for tissue engineering, and for studying funda-
mental scientific problems.
    One facet of Bhargava’s research seeks to create an automated
method for determining whether certain kinds of prostate cells have

From Beckman to Wall Street:

Schaeffer leverages cube experience into High-powered Position
Ben Schaeffer got his Ph.D. from the University of Illinois and some valuable real-world experience at the Beckman Institute
before leaving his Midwestern roots behind for the opportunity and bright lights of Wall Street and New York City. Schaeffer
left a huge mark at Beckman as the primary author of the software code that powers the Cube, the immersive virtual
reality environment operated by the Institute’s Integrated Systems Laboratory (ISL). Schaeffer now works on Wall Street
as a quantitative analyst in the field of computerized securities, but he hasn’t forgotten his alma mater or the people who
helped shape his experience at Beckman and Illinois. The Office of External Relations recently asked Schaeffer about his
experiences at Beckman and Illinois, his successful career, and other topics in an e-mail question-and-answer session.
