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. 

Amishi Jobanputra - Clinical Research Manager

Amishi joins the pediatric orthopedic surgery division as the Clinical Research Manager. She has her Master’s in Biochemistry and has gathered experience working in quality control, quality assurance, pre-clinical research, and phase 1B to 4 clinical trials. She has been directly involved in developing various research studies and projects including investigator initiated studies (IND). She manages clinical research operations for the pediatric orthopaedic surgery division and works with research coordinators and PIs in study set up, feasibility, budgeting, regulatory, data management, sponsored trials and student/residents/fellow projects.

Clinical Research Coordinators

Arianne Salunga, DO - Clinical Research Coordinator

Arianne received her medical degree from Touro College of Osteopathic Medicine (NYC) in June 2024 and is enthusiastic to join our team as a research coordinator. Her journey began with the NYU Langone Orthopedic Surgery summer externship after her first year of medical school, where she engaged in both clinical and research endeavors. Notably, she co-developed the study, “Sports Participation Levels Among New York City’s Kids Remain Low Months After the Covid-19 Pandemic”, which utilized a retrospective survey that assessed sports participation in children ages 6-17 with musculoskeletal complaints. The study’s findings highlighted significant declines in gym class and free play, emphasizing the need to return to physical activity as it is crucial for their overall well-being. Arianne’s growing passion for improving children’s health through a research and orthopedic standpoint has led her to Stanford, where she is eager to expand her skills and contribute meaningfully to the field alongside Dr. Vorhies and the pediatric orthopedic spine team. 

Bryan Khoo, BS - Clinical Research Coordinator

Bryan, a Seattle native, is graduating from Stanford University in June 2025 with a Bachelor of Science in Management Science and Engineering. Over the past three years, he has conducted research under Dr. Kevin Shea, applying machine learning and statistical shape modeling to characterize the prototypical development of the adolescent patellofemoral joint. He is excited to continue contributing to pediatric orthopedic research through anatomical studies, biomechanical investigations, and technical analyses. Bryan aims to advance the field by integrating emerging technologies into orthopedic research and clinical applications.

Alexa Eichelmann, MSc - Clinical Research Coordinator

Alexa completed her BSc in Sport and Exercise Science before earning an MSc in Clinical and Public Health Nutrition at University College London (UCL). Her master's research focused on low energy availability in female athletes, aiming to inform proactive safeguarding strategies to prevent Relative Energy Deficiency in Sport (REDs). Drawing on her background as a former athlete and her experience in sports performance, she is passionate about optimizing human performance through a health-first approach. Alexa is excited to contribute her multidisciplinary perspective to support practical research that advances our understanding of female health and human potential with Dr. Kraus and the FASTR Team.
