Michael Robert Hoffmann, James Irvine Professor of Environmental Science, and his team of graduate students Asghar Aryanfar, Clement Cid, Kangwoo Cho, Daejung Kwon, and Hao Zhang, along with post doctoral scholar Yan Qu have won the Reinventing the Toilet Challenge issued by the Bill and Melinda Gates Foundation. Their winning proposal was to build a toilet that uses the sun to power an electrochemical reactor. The reactor breaks down water and human waste into fertilizer and hydrogen, which can be stored in hydrogen fuel cells as energy. The treated water can then be reused to flush the toilet or for irrigation. [Caltech Feature] [CNN Ideas]
Ares J. Rosakis, Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering, and Michael R. Hoffmann, James Irvine Professor of Environmental Science have been elected to the National Academy of Engineering (NAE). Professor Rosakis was elected for discovery of intersonic rupture, contributions to understanding dynamic failure, and methods to determine stresses in thin-film structures. Professor Hoffmann was elected for oxidative treatment technologies for the removal of organic and inorganic contaminants from water.
All of the 24 ranked graduate programs at Caltech have placed exceptionally high in the National Research Council (NRC) study of more than 5000 graduate research programs, validating the Caltech approach to graduate education. With respect to the EAS Division: Aeronautics, Bioengineering, Civil Engineering, Electrical Engineering, Environmental Science and Engineering, and Materials Science were ranked in the top five nationally irrespective of size.

The Terrestrial Hazard Observation and Reporting Center (THOR) has been launched in an effort to find ways to minimize the damage caused by natural hazards. THOR will span two academic divisions at Caltech, Engineering and Applied Science (EAS) and Geological and Planetary Sciences. "The interdisciplinary and interactive nature of engineering at Caltech allows us to translate scientific knowledge and discovery into applications with direct societal impact," says Ares Rosakis, Theodore von Karman Professor of Aeronautics and Professor of Mechanical Engineering; EAS Chair. "One of the areas of pioneering research and innovation made possible by THOR is seismo-engineering. The boundaries of seismo-engineering are fuzzy ones and lie exactly in the interface between seismology and earthquake engineering. We are delighted to have the opportunity to explore these boundaries." [Caltech Press Release]
