  • Kierra Falbo Wins 2017 Becker Award
    09/08/2017

    Kierra Falbo (MPO 2018), recipient of 2017 Becker Award.Kierra Falbo, a graduate student at NUPOC in the MPO class of 2018, received the 2017 Otto and Lucille Becker Award for the best orthotics abstract submitted as a poster for presentation at the AOPA National Assembly. She is the first NUPOC student to win this award. Established in 2012, the Otto and Lucille Becker Award encourages students and residents to present posters of exceptional content. Ms. Falbo accepted the Becker Award in person at the 2017 AOPA national meeting in Las Vegas, NV.

    Ms. Falbo presented the poster, Characteristics of Delphi Processes in Orthotics and Prosthetics Research, at the AOPA meeting. The content is based on her NUPOC capstone research project under the mentorship of John Brinkmann, MA, CPO, FAAOP(D). Ms. Falbo said, “In addition to clinical work, I am very interested in research. I’ve been working as a research assistant on a research project with Mr. Brinkmann. I like to do things really well and in depth.

  • Andrew Conklin Exhibit Opens at NUPOC
    09/06/2017

    The Andrew Conklin Exhibit is at the NUPOC Gallery in September and October 2017

    At NUPOC, science, technology, and art intersect. In recognition of the artistry that is vital to prosthetics and orthotics, NUPOC is delighted to announce the installation and exhibition of oil paintings by Andrew Conklin. Mr. Conklin holds a BFA from the American Academy of Art (Chicago) and an MFA from the Academy of Art University (San Francisco), with postgraduate instruction at the National Academy of Design (New York) and from portraitist Aaron Shikler, painter of the official John F. Kennedy White House portrait.

    As a contemporary artist, Mr. Conklin continues the traditions of representational depiction and narrative content in painting. “My favorite subject is the human figure. The human body continues to play a vital role in my work, presenting technical demands and opportunities to explore its spiritual, moral and political condition in contemporary culture.” Mr. Conklin’s paintings challenge the viewer to consider complex life experiences and to examine the human condition as both progressive and unchanging. Mr. Conklin’s recent series of Motion Capture Studio paintings are particularly relevant to NUPOC research that uses motion capture to analyze human gait and motion.

    Artists and Certified Prosthetist-Orthotists (CPO) cultivate similar skills. A maxim holds that a good prosthetist-orthotist needs the triad of “head, heart, and hands”. Superior cognitive ability, compassion, and hand skills enable CPOs to serve their patients well. As scientists and clinicians, CPOs are rigorously trained in human anatomy, biomechanics, behavioral sciences, professional issues, practice management, and independent research. They also employ creative artistry that bridges science and technology to fit and fabricate functional, comfortable, wearable prostheses and orthoses.

    NUPOC appreciates Andrew Conklin and the Palette and Chisel Academy of Fine Arts (Chicago) for making this exhibit possible.
