Genetic Dissection of Heart Development in the Fruit Fly Drosophila Melanogaster
… conserved. The Drosophila heart, known as the dorsal vessel, functions as a pulsatile tube-like organ containing an inner layer of contractile cardial cells that adhere tightly to an adjacent layer of pericardial cells. A genetic screen for genes that control Drosophila heart development …

Determining the differential roles of the dock family of GEFs in drosophila development
… muscle, central nervous system (CNS), or the dorsal vessel (dv). Moreover, we confirm the in vivo role of Mbc upstream of Rac and provide evidence that Spg functions in concert with Rap1 to regulate aspects of adhesion. Together these data show that Mbc and Spg can have differential downstream …

The mechanical linkage of abdominal movements and the respiratory system in beetles
… system, with flow driven largely by the small dorsal vessel. Within the open coelom, hemolymph pressure should be mostly uniform, suggesting that abdominal pumping does not produce hemolymph flows within the main body cavity. We tested this assumption by simultaneously measuring hemolymph …

Structural and Physical Characterization of Insect Flow Systems
This dissertation characterizes the geometry, kinematics, and physical properties of insect internal structures that make up the respiratory and circulatory systems. This characterization is necessary to better understand how these systems function to transport fluids at the microscale, and …
