We are a research group at Indiana University and the Instituto Gulbenkian de Ciencia working on complex networks & systems. We are particularly interested in the informational properties of natural and artificial systems which enable them to adapt and evolve. This means both understanding how information is fundamental for controlling the behavior and evolutionary capabilities of complex systems, as well as abstracting principles from natural systems to produce adaptive information technology. Our research projects are on complex networks & systems, computational and systems biology, and computational intelligence, and our publications are available online.

See our current roster and information on how to join our group. We are seriously interconnected with other research groups and networks: The Center for Complex Networks and Systems (CNets), the Indiana University Networks Institute, the Cognitive Science Program, the FLAD Computational Biology Collaboratorium, the Instituto Gulbenkian de Ciência, the Champalimaud Neuroscience Program, and Centre de Physique Théorique at the Aix-Marseille Université.

Meetings for Spring 2017

Congratulations to CASCI members Alexander Gates and Santosh Manicka for successfully defending their dissertations entitled "The anatomical and effective structure of complex systems" on April 3rd 2017 and "The Role of Canalization in the Spreading of Perturbations in Boolean Networks” on April 24th 2017, respectively. Alex was co-supervised by Randy beer and Luis Rocha and completed a dual-PhD degree in the Complex Systems track of the Informatics PhD Program as well as the Cognitive Science program at Indiana University; He has accepted a postdoctoral position at Northeastern University at the Center for Complex Network Research. Santosh was supervised by Luis Rocha and completed his PhD degree in the Complex Systems track of the Informatics PhD Program.
