Research Interests & Responsibilities

I have been a member of the Joyner Lab since July 2000. Previously, I worked at Beth Israel Medical Center in Boston, MA. My primary responsibilities include maintaining mouse lines and assisting post-docs with a variety of techniques. In addition, I help maintain laboratory equipment.
