Fourth-year graduate student Shannon Martin was recently awarded an NIH F31, an Individual Predoctoral Fellowship from the National Heart, Lung, and Blood Institute (NHLBI). Shannon is a degree candidate in the lab of Jessica Plavicki, and uses the zebrafish model to study how exposure to common environmental toxicants perturbs the development and cell-cell interactions in both cardiac and neurodevelopment. The title of her proposal is "Determining the role of macrophages in the developing cardiac conduction system". The NHLBI supports training programs to prepare individuals to become productive researchers in the causes, diagnosis, treatment, and prevention of diseases of the heart, blood vessels, lungs, and blood; and in the uses of blood and blood resources. Congratulations Shannon!
