Breydon Hardy

Breydon Hardy, B.S.

Graduate Teaching Assist

Breydon Hardy is a graduate student completing his dual Bachelor’s and Master’s degree in Biomedical Engineering with an emphasis in Biomechanics. His undergraduate and now graduate research focuses on developing an alternative method to model muscle moment arms of the glenohumeral joint following reverse total shoulder arthroplasty. He has been working with Dr. Henninger’s team since his sophomore year of undergraduate, and was the recipient of a UROP award for his research in 2023. In his free time, Breydon enjoys volunteering, skiing, and weightlifting.

Tyler Adamson

Tyler Adamson

MS Student Research Assistant

Tyler Adamson is a graduate student working towards his dual Bachelor's and Master's degree in Biomedical Engineering. During his undergraduate years he worked as a research assistant in Dr. Andrew Anderson's lab, where he focused on the joint reaction forces associated with femoroacetabular impingement. He joined the Henninger lab in the summer of 2025 where now his graduate research seeks to validate novel motion capture techniques against standard marker tracking for upper extremity motion and use in clinical settings. In his free time Tyler loves to be outdoors, climbing, hiking, and camping.

Jared Zitnay

Jared Zitnay, PhD

Research Scientist

Jared joined the Orthopaedic Research Laboratories in 2020 where he works with the research groups of Drs. Heath Henninger and Andrew Anderson.  Jared’s activities cover the range of research in the ORL and include supporting the research of undergraduate and graduate students, assisting human-subjects motion capture studies, conducting benchtop experiments, and developing tools for data processing and analysis.  Before joining the ORL, Jared earned his Bachelor of Biomedical Engineering degree from the University of Minnesota, Twin Cities.  As an undergraduate research assistant in Prof. Victor Barocas’ laboratory, he studied the mechanics of the intervertebral disc and facet capsular ligament of the lumbar spine.  Also, during his time in Minnesota, Jared worked as a student technician for the Department of Biomedical Engineering’s Tissue Mechanics Laboratory.  In 2014, he came to the University of Utah to pursue his PhD in Biomedical Engineering, under the mentorship of Prof. Jeff Weiss, investigating basic mechanisms of mechanical damage in tendons.  Through interdisciplinary collaboration with groups at the U of Utah and MIT, Jared’s research employed a novel triple-helical peptide hybridization method to detect denatured collagens and identified mechanical unfolding of the collagen triple-helix as a fundamental mechanism of damage in tendons.  In his free time, Jared enjoys exploring Utah’s mountains and deserts with his wife and dog and singing in a local community choir. 

Residents

Medical Student

Mitch completed his Bachelor of Biomedical Engineering at the University of Utah with an emphasis on biomechanics and a minor in chemistry. He began working with Dr. Henninger in 2018 as an undergrad and completed his capstone thesis on subsampling as a viable method to increase data processing efficiency in biplane fluoroscopy motion tracking. He began medical school at the University of Utah in 2021 with an intent to pursue a career in orthopaedic surgery and returns to Dr. Henninger’s lab as a gap year research fellow with the Shoulder and Elbow surgery division. His research includes loosening and failure analysis of anatomic arthroplasty glenoids as a function of inclined glenoid inclination, and biomechanics of lesser tuberosity osteotomy repair constructs. Outside of research, Mitch also enjoys medical device innovation and is a recipient of the “People’s Choice” and  “Grand Prize Runner-Up” awards at the statewide Bench to Bedside bio-innovation competition. His most recent venture, OrthoBolt, is a novel take on an expanding pedicle screw, and the company is currently prototyping and seeking investor funding. Mitch is an avid University of Utah athletics fan and enjoys skiing, backpacking, road and trail running, including a recent rim-to-rim-to-rim ultramarathon in the Grand Canyon.

Kyle Christy

Kyle Christy, B.S.

Aspiring Medical Student

Kyle earned a Bachelor’s in Biology with an emphasis in Anatomy and Physiology and a double minor in Chemistry and Economics from the University of Utah in 2024. As an undergraduate he conducted research in the lab of Dr. Lisa Cannon-Albright and Dr. Kristina Allen-Brady studying genetic epidemiology. After graduating, he joined Dr. Henninger’s team in the summer of 2024. Here he is studying glenoid morphology pre-revision shoulder arthroplasty focusing on three-dimensional classification. Kyle’s career objectives are to attend medical school and become an orthopedic surgeon. In his free time, he enjoys snowboarding, weightlifting, cooking, and spending time with his friends.
