Research Interests
Running is one of the most common modes of recreational exercise in the United States. Unfortunately, rates of running related injuries remain high despite technological advances in footwear, knowledge of appropriate training methods, and vast amounts of research pertaining to injury mechanisms. Numerous gait characteristics have been identified as potential risk factors for the development of overuse running injury; however, there is a lack of consistency between studies regarding the kinematic and kinetic patterns and events that may or may not cause running injuries. As a result, it seems that we are no closer to understanding the mechanisms of running injuries or how they can be prevented.

My research takes an interdisciplinary approach and uses advanced analysis methods to investigate the mechanisms of running related overuse injuries and the determinants of running economy. I combine biomechanical data with experimental oxygen consumption and substrate utilization data, both experimentally and via musculoskeletal and muscle energetics models, to comprehensively examine the interaction and importance of gait energetics on injury mechanisms. I also use advanced analysis methods, such as multiscale entropy, wavelet transform, and a modified vector coding technique, to investigate coordinated movement patterns and the motor system's response to interactions with the environment. Investigating coordinated movements and non-time domain variables may be the key to understanding the causes of chronic running injuries and how these injuries can be prevented.
