Research directions

 

We are focused on the following interdisciplinary research directions:

 

Large-scale intelligent processing of signals

Based on concepts in multivariate statistical analysis and optimization, we develop pattern recognition techniques to process and analyze a large amount of information that lead to “intelligent” decision making. Ongoing applications include predictions in health and security problems, humanitarian demining, smart metering analysis, and 3D reconstruction in computer vision.

 

Design and analysis of interconnected dynamical systems

There are many complex processes whose behavior can be modeled and analyzed as the result of the interaction of simpler dynamical systems. We develop mathematical and computational tools that allow for a better understanding and control of such processes. Ongoing applications include trajectory design in cooperative autonomous vehicles, cybersecurity in distributed systems, and design of sparse control systems.

 

Modeling human social systems

In engineering, we have a toolbox with theoretical and practical elements that can help address social problems through the modeling and analysis of human social systems. Ongoing projects include the design of cooperation strategies in poor communities based on optimal control, modeling and analysis of behaviors in high-risk alcohol consumption, and modeling social dilemmas and mechanisms that promote social responsibility.
