Metzger Lab

Joseph MetzgerWe seek mechanistic insights into normal and diseased cardiac muscle function. Our overarching goal is to translate basic science discoveries into potential therapeutic strategies to combat inherited and acquired forms of heart disease. Lab projects embrace individuality, emphasize cooperation and collaboration, and encompass a standard of excellence to all that we do as individual researchers and as a laboratory. Our guiding principles are to treat others with respect and courtesy, to maintain the lab in a collegial, safe and professional environment, and to work each day to fullest of our capabilities.
