Bella Beortegui, B.S. Bella is a Ph.D. student in Mechanical Engineering and Material Science. Her research interests include knee biomechanics, especially pertaining to athletes and the particular injuries they endure such as continuous tearing of the cruciate and collateral ligaments. bella.beortegui@duke.edu |
 |
Jefferson Bercaw, B.S. Jefferson is a Ph.D. student in biomedical engineering. His research interests include ACL and meniscus injury mechanisms, and sex-related differences in ACL and meniscus injury risk. jefferson.bercaw@duke.edu |
 |
Stephanie Danyluk, M.S. Stephanie is a Clinical Research Coordinator for the DeFrate Lab. Her role in the lab is mostly regulatory, as she manages all clinical studies involving patients. She makes sure that each study is conducted efficiently, safely, and within the guidelines of ICH’s “good clinical practice.” Within her role, she deals directly with research participants, investigators, and the Institutional Review Board. stephanie.d.thompson@duke.edu |

Chris Otap, B.S. Chris is a research technician II investigating the effects of weight loss, ACL, and meniscus repair on cartilage strain and the development of post-traumatic osteoarthritis. chris.otap@duke.edu |
 |
Anisha Karnik, B.S. Anisha is an M.S. student in biomedical engineering. Her interests include applying biomechanics principles to medical device development, and she plans to pursue a career in the medical device industry. anisha.karnik@duke.edu |
 |
Sebastian Pino Sebastian is a molecular biotechnology engineer working as a Research Technician II, currently focused on elucidating how specific systemic molecular biomarkers relate to structural changes in the knee joint during osteoarthritis progression, in the context of obesity and meniscus and ACL injuries. sebastian.pino@duke.edu |
 |
Xingqi Su, B.S. Su is a Ph.D. candidate in biomedical engineering. She is investigating the risk factors for low back pain by evaluating in vivo lumbar intervertebral disc mechanics under dynamic loading and during motion. xingqi.su@duke.edu |
 |
Marianne Voigt, B.S. Marianne is a PhD student in biomedical engineering. Her research interests include ACL injury mechanisms and how sex-based differences, particularly regarding hormonal influence and the menstrual cycle, affect knee mechanics and injury. marianne.voigt@duke.edu |
 |
Ucheena Woodfolk, B.S. Ucheena is a PhD student in Biomedical Engineering. She has a B.S. in Mathematics from Spelman College and a B.S. in Bioengineering from North Carolina A&T State University. She is interested in applying biomechanics and mathematics to investigate rehabilitative health in areas such as ACL injury mechanisms, injury rate differences in diverse research demographics, and meniscus injuries. ucheena.woodfolk@duke.edu |
