Our lab studies the biomechanics of motion in animals, conducting integrative research that crosses traditional boundaries of engineering and biology. Currently, two broad themes of our research center around gliding flight in vertebrates and internal fluid flows in invertebrates. We aim to understand animal movements both for fundamental understanding of animal physiology, ecology and evolution, and as inspiration for novel engineering applications.

Other research is focused on the development of accurate material models for hard and soft tissues based on material test data obtained by our group members, and the design of adaptive restraint systems for self-driving cars.
In order to assure the safety and reliability of critical assets understanding the science of how systems degrade and how this damage affects performance is critical. The Damage Science and Mechanics Laboratory works within the multiple disciplines needed to achieve this goal. Sustainable system planning and design, life-extension, system prognostics, system and structural health monitoring are areas where this work finds applications.
The Kevin P. Granata Biomechanics Lab is the current center of research for Robin Queen, who is a fellow of the American College of Sports Medicine. She was previously the director of the "Coach K" Lab at Duke University where she worked with a variety of industry sponsors including the Nike Sport Research Lab and DonJoy Orthopedics. Her focus is on lower extremity biomechanics with an emphasis in foot and ankle biomechanics. Her work focuses on understanding changes in lower extremity loading and movement symmetry that result from injury and pathology. In addition, Dr. Queen works on development of various interventions to restore movement and loading symmetry in an attempt to decrease future risk of joint damage and prevent subsequent injuries.

Over the past 60 years, researchers across the planet have worked to understand the biomechanics of concussion and associated brain injuries. This chapter presents a summary of these efforts that begin with the human cadaver research performed in the 1950s and served as the foundation for the severity index and head injury criterion injury metrics. Following this research, experiments were performed on primates in order to quantify the injury physiology associated with concussion. More recently, the National Football League reconstructed concussive impacts and presented the first injury risk functions for concussion. The fourth dataset includes over two million head impacts measured with helmet instrumentation on volunteers playing football. By analyzing all of these data together, researchers have presented an array of injury risk functions for concussion that use both linear and rotational head acceleration parameters. Laboratory experiments utilize these risk functions to evaluate the performance of helmets and their ability to reduce the risk of concussion. Clinical studies have been performed that support and confirm the laboratory findings. The future of helmet testing will utilize a new impact system that more accurately reflects the head and neck kinematics the players experience during head impacts in sports.
The Nature-Inspired Fluids & Interfaces Lab is led by Dr. Jonathan Boreyko.

The Orthopedic Mechanobiology Laboratory at Virginia Tech was established in 2015. Our laboratory mission is to improve the diagnosis and treatment of skeletal soft tissue injuries through translational research studies.
Musculoskeletal soft tissues such as tendon, ligament, cartilage, and meniscus are composite biological structures that serve vital mechanical functions during activities of daily living.
Ongoing research investigations can be broadly categorized as follows:

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.
Since 2011, Virginia Tech researchers have been providing unbiased helmet ratings that allow consumers to make informed decisions when purchasing helmets. The helmet ratings are the culmination of over 10 years of research on head impacts in sports and identify which helmets best reduce concussion risk. This work is done as part of Virginia Tech’s service mission and is 100% independent of any funding or influence from helmet manufacturers.
