A visualization of the human brain using VisTrails. In recent decades, researchers have used computers to build complex visualizations based on large data sets to gain a better perspective on their research. A computer-generated visualization can help a surgeon better understand what is happening inside a patient's heart before ever picking up a scalpel.

If you're feeling a little overwhelmed by all the information you have to keep track of, you're not alone. Between the proliferation of 'smart' devices — ranging from phones to power grids — and the ever-growing Internet, the world is drowning in data. But not to despair, computer scientists like Juliana Freire are trying to help us gather and make sense of this modern monsoon of data. A computer scientist at the University of Utah, Freire's work centers on finding data that might otherwise be missed, as well as integrating and managing that data into knowledge that people can actually use. She and her collaborators have created the DeepPeep project, an attempt at integrating typical web-based data with other databases that are publicly available, but not easily found through standard methods like online searching. Freire has also created a tool called VisTrails that allows users to take several computers and 24 large, flat-screen video monitors and produce a single high-resolution visualization, such as the brain's vascular system or the dynamics of an erupting volcano. For more about the work, see the recent NSF Discovery feature story. For more on Freire, see her answers to the ScienceLives 10 Questions below.
