Thesis Research: 

Titin, a sarcomeric protein, is the largest protein in the body, and along with the extracellular matrix is responsible for diastolic properties in the heart.  Recent exciting evidence indicates that Titin plays a significant role in pathological hypertrophy signaling.  By utilizing multiple mouse models in which specific sequences have been deleted from the titin gene, I am investigating how stress and strain on the giant sarcomeric protein titin regulate hypertrophy signaling.
