About

The Eames lab uses molecular genetics and advanced imaging techniques to understand how skeletal tissues develop and evolve.  A general focus of the lab is on skeletal cell differentiation.  What are the external signals that direct undifferentiated cells to turn into bone or cartilage cells?  How are these signals interpreted by cells to activate pathways of differentiation?  On the one hand, the Eames lab is interested in applying answers to these questions to such debilitating diseases as osteoarthritis.  On the other hand (and these hands know each other), the Eames lab is interested to know how these same answers vary among chordate clades.

Since studying HIV during my undergrad, I became fascinated with understanding molecular mechanisms of evolution. In fact, I was accepted into grad school with the presumption that I would be a molecular virologist. But then I discovered the power of using embryonic development to study evolution.

The skeletal system seemed fruitful to analyze. Ironically, my first job in science was getting stem cells to make bone in a dish, so after those intervening 5 years, I really came full circle. I figured that any genomic understanding of evolutionary changes to skeletal anatomy would require knowledge of the genes that drive cells to make skeletal tissues in the first place.

On the practical side, I love the idea that my science can help people to  live more active and healthy lives--my findings can be applied as therapies for bone fractures, osteoporosis, osteoarthritis, and many other serious contributors to inactivity in humans today. On the esoteric side, I love the idea that my work can serve as a textbook example of the genomics of trait evolution.Current Re
