• Our eyes are composed of living tissues, which are constantly remodeling in response to mechanical, chemical, and visual stimuli. In particular, the loadbearing collagenous structures of the eye can undergo substantial growth and remodeling during physiological and pathophysiological conditions. I seek to elucidate the biomechanical mechanisms that underlie growth and remodeling in ocular diseases. My laboratory focuses on establishing experimental methods and predictive computational simulation tools for elucidating growth and remodeling mechanisms in glaucoma, keratoconus and myopia. My laboratory‚Äôs goal is to provide predictive computational simulation tools that support the development of new diagnostics and therapeutics in ocular diseases and conditions.
