Researcher to track spread of disease, malware and power outages

and improve robustness in the areas of health care, computer networking and power grid controls, in order to address key concerns for health care workers, computer industry personnel and various policy planners. He also will develop realistic models and scalable, efficient simulation tools for understanding diffusion processes within complex network systems vital to the Department of Energy.

The main challenges of the project include the huge variability in the scales and unstructured properties of the kinds of networks that arise and limited real data and models, Vullikanti said. "We will use both theoretical and large scale simulation based methods to address the challenges of complex networks," he added.

The Career Principal Investigator grant is given to faculty in the early stages of their academic profession in the fields of applied mathematics, computer science, computational science and high-performance networks, bolstering the nation's scientific workforce by providing support to exceptional researchers during the crucial early career years, when many scientists do their most formative work.

This grant comes after Vullikanati won a National Science Foundation CAREER award (http://www.cs.vt.edu/node/4691) a year ago for his work on Cognitive Radio Networks (CRNs). Funded at $450,000 for a five-year period, the research focuses on theoretical foundations of CRNs, which increase the spectrum utilization by opportunistically allowing unlicensed users to transmit on licensed bands without intruding on the users who are licensed. The proposed study included research on cross-layer optimization problems in such networks using a more realistic model of interference.
