The STRETCH lab investigates the relationship between the mechanical behavior and complex structure of biological systems by combining experimental, theoretical, and computational methods. Ligaments, tendons, muscles, tracheae, cells, and lipid bilayers are examples of biological systems that are currently studied in the lab.
My research focuses on reducing the risk of crashes and crash injury for occupants of autonomous cars and for the vulnerable road users which these new vehicles will encounter, e.g. pedestrians and bicyclists. Areas of research include injury biomechanics, injury countermeasures, data analytics, active safety systems, event data recorders, crash epidemiology, and crash modeling.
I have a background in solid mechanics and mechanical engineering, which I have leveraged, in conjunction with my training as a biomedical engineer, to make advancements in the field of accelerative loading injury protection. My specific graduate training at VT&WFU revolved around the biomechanics of injury. While my strongest area is in computational biomechanics, my research encompasses projects touching on all aspects of civilian and military injury biomechanics, including projects in human model development and morphing, injury metric development, risk curve development, thermal burns and therapeutics, and the basic-science aspects of injury biomechanics.
My research in the field of injury biomechanics specializes in characterizing the biomechanical response and injury tolerance of biological tissues under dynamic loading conditions. This research provides crucial data for the development and validation of improved anthropomorphic test devices and finite element models used to assess injury risk in automotive and military loading environments.
The main focus of our work is on occupational injury prevention and performance enhancement, particularly in the manufacturing, healthcare, and construction sectors. Other major lines of research include fall prevention among elderly individuals, as well as non-invasive fall detection and behavioral monitoring. Our work is diverse, including both basic and applied emphases.
Our mission is to investigate the dynamics and neuromuscular control of human movement, and to train scientists to become leaders in the fields of musculoskeletal, sports and orthopaedic biomechanics. The primary focus of the research conducted in the Granata Lab is injury prevention. Projects in the lab fall into 3 main categories: Athletic Injury Prevention, Lower Extremity Joint Arthritis and its impact on Movement, and Alterations to Movement that result from injury and pathology.
I am a translational biomedical engineer whose research focus is on studying the physiologic response to traumatic injuries. Specifically, my lab focuses on studying the pathophysiology of hemorrhagic shock, traumatic brain injury and resuscitation. This includes intense investigation of blood, saliva and urine-based biomarkers to help guide therapy to those with critical injuries and also developing targeted treatments for various injury types.
My research focuses on investigating human tolerance to impact loading, with specific interests in: brain injury, skull fracture, protective design, and safety evaluation systems. My primary focus is geared towards investigating the causation and prevention of concussion.
The research at the Laboratory for Fluid Dynamics in Nature (FiNLab) is focused on two main themes: fluid flows in nature, and advanced computational methods for fluid flows. The natural systems studied at FiNLab range from insect respiratory flows, which occur at the microscale, to planetary atmospheric flows with length scales on the order of tens of kilometers. There is an emphasis on biomimetics for efficiency, resilience, and sustainability, on high performance computing, and on advanced multiscale computational modeling.

For paediatric population and children with single functional ventricle, Fontan operation helps to reroute the deoxygenated blood to the lungs. However, the non-physiologic flow patterns created by the Fontan procedure lead to an increase in chances of platelet deposition and pressure loss which calls for heart transplantation to prevent early and late stage pathophysiology. The Turbomachinery Lab is focused on developing a TCPC connector to reduce the pressure and energy loss and thereby unload the single functional ventricle to ensure longer survival period. A dual propeller micro-pump is developed in conjunction with the TCPC connector for augmenting the systemic pressure and thereby regaining the normal circulatory physiology in Fontan patients.
The Computational Biomechanics Group headed by Dr. Untaroiu is part of the Center for Injury Biomechanics (CIB) at Virginia Tech, one of the leading research entities in the world in the area of injury biomechanics. Untaroiu’s group use a multidisciplinary approach in solving various real-world impact biomechanics problems. Our current projects include the development and validation of pedestrian human models with different anthropometries for automotive manufactures, and the development and validation of a lower limb dummy finite element model for under-body blast events for the Army Research Lab.

The Traumatic Nerve Technologies (TNT) lab conducts research in many diverse areas! We are taking a multidisciplinary approach to understanding nerve injuries, cell repair strategies and technologies that assist in prevention, identification and treatment of nervous tissue injuries. By advancing the fundamental understanding of the behavioral, morphologic, and molecular mechanistic repercussions accompanying traumatic injuries, we will further identify molecular targets and outcome measures needed for effective treatment strategies.

Dr. Weaver is involved with a variety of projects primarily focused on motor vehicle crash, spaceflight, military, and sports-related traumatic injury. These projects involve medical image analysis to characterize bone mineral density, cortical thickness, and morphology across populations, development of subject- and population-specific anatomical models, and finite element modeling. She leads a NASA study to collect pre- and post-flight CT and MRI scans of astronauts to measure bone and muscle degradation that occurs in long-duration spaceflight. Several of her projects simulate automotive and spaceflight loading scenarios to predict injury risk using human body models. She is also involved with CT and MRI studies to develop anatomical models for medical device design applications.
