Welcome to our website.
Please feel free to explore our website and learn more about what we do. The Laboratory for Complex Systems and Nonlinear Dynamics in Fluids and Granular Materials is directed and advised by Julio M. Ottino.
We are active participants in interdisciplinary research. For example, our group is strongly involved with the Northwestern Institute on Complex Systems (NICO).
For recent publications, select Publications in the menu above. Also see the new Classic Papers section under Publications.
In the News
- Julio M. Ottino reviews two biographies of Henri Poincaré in the October 2013 issue of Physics Today.
- Julio Ottino spoke to IBM about the importance of whole-brain thinking™ at THINK: A Forum on the Future of Leadership. See the video.

- In September 2008, J.M. Ottino co-organized an NSF workshop with John Guckenheimer from mathematics at Cornell University titled "Foundations for Complex Systems Research in the Physical Sciences and Engineering." The workshop was charged with identifying barriers and gaps that impede complex systems research. The report can be accessed here.
- Former Ottino student appointed Director of IIT Bombay: Prof. Devang Khakhar, a student of Julio M. Ottino at the University of Massachusetts Amherst, has been appointed as the new director of IIT Bombay as of January 1, 2009. He joined the Department of Chemical Engineering at IIT Bombay in January 1987, and has been with the institute since then.
- Professor Julio M. Ottino has received one of the most prestigious awards in physics, the 2008 Fluid Dynamics Prize of the American Physical Society (APS). The prize recognizes and encourages outstanding achievement in fluid dynamics research.
