  • Introducing Julia Quinlan, PhD

    Julia Quinlan, PhDJulia Zelenakova Quinlan, PhD, has joined NUPOC as a Postdoctoral Fellow sponsored by a NIDILRR Advanced Rehabilitation Research Training Grant (Principal Investigators, Steven A. Gard, PhD, and Zev Rymer, PhD). During the one year grant period, Dr. Quinlan will work on a Department of Defense funded research project, No Longer Smooth: Introducing Striations into Prosthetic Socket Construction to Improve Suspension, Rotation, Fit and Comfort, led by Principal Investigator Stefania Fatone, PhD, BPO(Hons). The project goals are to investigate the effect of different types of texturing on suspension, rotation, fit, and comfort, specifically to test if horizontal striations improve suspension; and if vertical striations help control transverse plane rotation for transtibial sockets.

    Dr. Quinlan will develop testing setups, fabricate required testing fixtures, and conduct experiments that will measure the coefficient of friction using sled and table friction; evaluate the tensile and static strength of sockets with different texturing patterns using a dumbbell specimen; and develop testing protocols for an INSTRON® material testing machine.

    Dr. Quinlan earned a doctorate in Bioengineering with a concentration in Biomechanics at the University of Illinois-Chicago (UIC); and a Master’s of Science in Biomedical Engineering with a concentration in Biomedical Engineering at The Technical University of Košice (TUKE), Slovakia. At TUKE, she was recognized with a Dean’s Award for Outstanding Graduate Student. Her doctoral dissertation addressed “Effect of Binge Alcohol Exposure on Intervertebral Disc Structure and Mechanical Properties in Adult Rats” and her Master’s thesis examined “Ambient Intelligence Tools Applied in Everyday Activities in the Home Environment”. Her work has contributed to 20 conference abstracts and presentations and she is a named author on 6 publications.

    In addition to her academic training, she also brings research experience in the Musculoskeletal Biomechanics Research Laboratory, Edward Hines Jr. Veterans Affairs Hospital, Hines, IL, where she conducted spine biomechanics and general orthopedics research. She has worked as a technology commercialization analyst and consultant at the UIC Office of Technology Management. During her doctoral training at UIC, she taught 6 years of classes in Senior Design I and II and Biomechanics.

    Her early interest in mathematics and science led her to apply and be immediately accepted into the highly competitive BME department at TUKE. Although education is state subsidized, acceptance to each stage of educational promotion is rigidly controlled by increasingly difficult entrance examinations. Dr. Quinlan reflected, “Typically, about 1,500 students will be accepted to begin a course of study, but ultimately only about 60 people will graduate. If a student fails a class, s/he has 2 years to pass it. Students who fail or drop out must re-apply through the examination system.”

    Born during communist rule in Czechoslovakia, after the dissolution of Czechoslovakia in 1993, Julia, her parents and younger brother lived in the independent and democratic Slovak Republic. To experience American culture firsthand and to hone her fluency in English, she spent 4 months in 2005 working for an exchange program in Yellowstone National Park where she developed strength and self-confidence by managing a series of life-changing personal and financial challenges. In 2006, prior to moving to the USA to pursue her doctorate, she spent a semester as a Socrates-Erasmus exchange student studying BME in Ghent, Belgium.

    Dr. Quinlan noted that although she had hoped to remain in Europe to better support her mother, “I must have been born with wandering boots. I’ve lived in Chicago for nearly 10 years and my husband is American, so my future is here in the USA.” Recently, she seldom has leisure time, but has played competitive intramural soccer, and is an accomplished gardener and seamstress. Dr. Quinlan said, “I enjoy attending theatrical and musical performances with my friends. I have attended the last eight seasons of the Chicago Lyric Opera”.

    Dr. Quinlan is passionately committed to research. She intends to pursue a career within a university setting where she can conduct research related to the biomechanics of the human musculoskeletal system, publish the results of her research, and share her knowledge by teaching students. We are delighted to welcome Dr. Quinlan and her multiple skills to NUPOC.

  • Introducing Xinru Chen, BS

    Xinru Chen, BS, is conducting her BME graduate research at NUPOC under the supervision of Steven A. Gard, PhD.Xinru Chen, BS, has joined NUPOC to conduct research in partial fulfillment of her Master’s degree in Biomedical Engineering (BME). Steven A. Gard, PhD, will guide Ms. Chen in her research on optimization of prosthetic foot and ankle stiffness to approximate able-bodied gait. Using mechanical testing, Ms. Chen’s project proposes systematic changes to foot-ankle stiffness to determine an optimum stiffness for biomimetic gait. She expects to complete her thesis work by May 2017. (Learn more about this Department of Veterans Affairs-funded research project: Optimization of Prosthetic Foot and Ankle Stiffness for Standing and Walking.)

    Ms. Chen graduated with a BS in Molecular Biomedical Sciences with first class honors and a minor in Information Technology (Hong Kong University of Science and Technology, 2012). She matriculated to Northwestern University for her graduate work, initially in Interdepartmental Neuroscience. She transferred to BME where she foresees that work in prosthetics can be more immediately applied to produce positive, tangible outcomes. She said, “I planned a graduate career in molecular neuroscience looking at individual cells. But I wanted to move up to a broader system level. I recognized that I wanted my work to be more clinically relevant to real people, not mice. That’s why I shifted my emphasis to BME and prosthetics research.”

    In microbiology and neuroscience, Ms. Chen has participated in a range of mentored and team research projects that include: analysis of synaptic organization; programing custom MATLAB® scripts to control and analyze electrophysiology experiments; optimizing a biochemical assay for quantification of total Amyloid β-derived synaptogenesis and PTEN-regulated axonal growth of retinal ganglion cells; and examination of the expression pattern and function of a gene expected to have a developmental role in C. Elegans. She contributed to the Silver Medal team in the International Genetically Engineered Machine Competition (iGEM, 2009), and has presented podium talks and research posters. She enjoys teaching and has volunteered as an instructor for hands-on science sessions and conversational Mandarin. 

    Her passion for science and engineering may have been natural outgrowths of exposure to her parents’ careers in computer science, civil engineering, physics and biology. Interested in theories and reasons, Ms. Chen frequently visited her mother’s office where she observed her mother’s civil engineering projects and appreciated their impact on people and the society.

    Ms. Chen enjoyed being an exchange student at the University of Wisconsin-Madison and said, “The winter weather was interesting.” In her free time, she enjoys kayaking, paddle boarding, and biking with her friends. Currently, she is considering various options and has not yet decided on her course after completing her Master’s degree.
