Theoretical Condensed Matter and Biological Physics
Just about every field of research is confronted with networks. Metabolic and genetic networks describe how proteins, substrates and genes interact in a cell; social networks quantify the interactions between people in the society; the Internet is a complex web of computers; ecological systems are best described as a web of species. In all these fields the detailed knowledge of the components is insufficient to describe the whole system. Since 1960, when Paul ErdÃ¶s introduced the influential random graph theory, complex networks have been modeled as fundamentally random graphs. Our work has mounted a serious challenge to this view. By investigating the topology of the World Wide Web, Internet, cellular and social networks, we discovered that networks in nature follow a common blueprint, having scale-free characteristics. These results represent a significant paradigm shift: scale-free networks and the associated dynamic network modeling are a completely unexpected turn of events with a strong impact on every research area for which networks are relevant. We are currently exploring a wide range of network structures, asking questions pertaining to the error and attack tolerance of complex networks, their robustness, and trying to address the dynamics of networks in general. We are also pursuing a strong research program applying network theory to biological systems, aiming to uncover the inner chemical architecture of the cell.

Researchers use science to predict success
Like the rest of the academic community, physicists rely on various quantitative factors to determine whether a researcher will enjoy long-term success.

Science of Success — Why are people actually successful?
Albert-László Barabási fielded questions about how someone or something becomes successful – it’s not always because he or it is the best.
Researchers to explore the ‘Science of Success’
We once thought it took a genius to be successful, but this is simply not the case.
Researchers transcend boundaries for science
Throughout the 179th annual meeting of the American Association for the Advancement of Science, Northeastern faculty led presentations highlighting their work to address real-world challenges in areas ranging from health to technology to sustainability.
Complex systems made simple
Just as the name implies, complex systems are difficult to tease apart. An organism’s genome, a biochemical reaction, or even a social network all contain many interdependent components—and changing any one of them can have pervasive effects on all the others.
