Research Management

Christian Klemt, MSc PhD - Research Program Manager

Christian Klemt completed his undergraduate degree in Mechanical Engineering at Berlin Institute of Technology. He joined Queen Mary, University of London to pursue a masters degree in Biomedical Engineering with a focus on musculoskeletal mechanics. To broaden his interest in musculoskeletal biomechanics, Christian joined Imperial College London in 2015 for a PhD aiming to customize musculoskeletal shoulder modelling utilizing Magnetic Resonance Imaging in order to more precisely assess joint functionality and joint stability for both native joints as well as joint replacements. Following the completion of his PhD, he joined the Bioengineering Laboratory at Massachusetts General Hospital/Harvard Medical School to study in-vivo hip and knee biomechanics of patients with total joint replacement. Additionally, Christian’s Post-Doctoral research involved the retrospective analysis of patient data to identify risk factors for poor patient outcomes and implant failure. Recently, Christian developed and validated artificial intelligence technology to predict post-operative outcomes and complications for patients following hip and knee arthroplasty surgery in order to assist clinical decision-making. 

In his free time, Christian enjoys meeting family and friends. He likes travelling to explore new cultures. He also has a keen interest in sports including soccer and cycling.

Clinical Research Coordinators

Hiba Naz, BS – Clinical Research Coordinator

Hiba is from Houston, Texas and graduated from University of California, Davis in September 2019 with a degree in Neurobiology, Physiology and Behavior. During her undergraduate she worked at the Center for Healthcare Policy and Research at UC Davis Health. She continued working at UC Davis Health after her graduation on several studies exploring barriers to cancer care for adolescent and young adults (AYAs) in low-and-middle-income countries in Latin America, barriers to AYAs’ participation in cancer clinical trials, symptom management for heart failure patients, and implementation of tobacco cessation services at UC Davis Health. Hiba is excited to support research and improve patient care and outcomes at Stanford’s Department of Orthopaedic Surgery.

Vanessa Taylor, BS - Clinical Research Coordinator

Vanessa is from Corvallis, Oregon and she completed her undergraduate degree at the University of Oregon in 2022. Studying Human Physiology and Sports business, she gained experience in Orthopedic and Biomechanics research as a research assistant. During her undergraduate she also completed a Sports Performance internship with the University of Oregon Football team exploring data analysis related to how competitive training techniques affect athletes. Vanessa will be working with Dr. Shea and is very excited to learn and advance her skills in orthopedic research.

Xochitl Bryson, BA - Clinical Research Coordinator

Xochitl is from Anaheim, CA, and graduated with a B.A. in Biological Sciences with a minor in Spanish Language & Literature from UC Davis in 2021. During her undergraduate career, she worked at the UC Davis Medical Center as a member of the research team within the Department of Emergency Medicine. At Stanford, Xochitl works for Dr. John Vorhies in the Department of Orthopaedic Surgery focusing on spine research. Xochitl is incredibly excited to be a part of this team and working toward improving patient care and outcomes through research.  


Research Data Analyst

Nicole Segovia, MPH - Biostatistician

Nicole is a biostatistician with Stanford University’s Department of Orthopaedic Surgery and a Bay Area local. She graduated from Cal Poly SLO with a BS in Statistics and from Imperial College London with a Master’s in Public Health.
