I am a biomechanist and evolutionary biologist at Harvard University, where I'm currently a PhD candidate in the Department of Human Evolutionary Biology. I'm broadly interested in the evolution of the human body and evolutionary perspectives on health. My current research focuses on the origins and function of human lumbar lordosis (curvature of the lower back), asking two main questions:
1. What biomechanical factors predict variations in hominin lumbar lordosis?
2. What are the biomechanical consequences of lordosis variations?
To answer these questions, I examine how the lower back acts as a viscoelastic system, showing both spring and damping characteristics in response to loading when we walk, run, and carry loads. Using morphometrics, modeling, and experimental methods, my research seeks to predict and test the effects of variations in lumbar curvature on loading behavior in vivo with the ultimate goal of understanding the epidemiology and natural history of spinal pathologies.
