DEPARTMENT OF ENERGY Computational Science Graduate Fellowship Welcome to THE 2016 incominG DOE CSGF class In fall 2016, 27 doctoral students – the biggest group yet – enter the Department of Energy Computational Science Graduate Fellowship (DOE CSGF). These fellows were chosen in a rigorous screening process from more than 350 applicants. Each will receive yearly stipends, full tuition and fees and other benefits for up to four years, freeing them to pursue research and training in applied mathematics, computer science and an application area of their choice.
