Karl Lewis, Ph.D.

Karl Lewis

Assistant Professor (summer 2020)
Meinig School of Biomedical Engineering

Biography

Dr. Lewis is presently a post-doctoral fellow at the Indiana University School of Medicine where he studies the role of brain interactions with bone in mechanotransduction. He will begin as an assistant professor at the Cornell Meinig School of Biomedical Engineering in the summer of 2020.

Dr. Lewis’s interests center on understanding the interplay of mechanical cues and biological changes in musculoskeletal tissues. Specifically, his work is centered on understanding how the acute sensing mechanisms in musculoskeletal cells relate to tissue level changes in healthy and disease states.
