"Our group is interested in the chemical transformations that are relevant to feeding and fueling the planet. There are two efforts on this campus in artificial photosynthesis, and I participate in both."
In developing nations, rural areas, and even one's own home, limited access to expensive equipment and trained medical professionals can impede the diagnosis and treatment of disease. Many qualitative tests that provide a simple "yes" or "no" answer (like an at-home pregnancy test) have been optimized for use in these resource-limited settings. But few quantitative tests—those able to measure the precise concentration of biomolecules, not just their presence or absence—can be done outside of a laboratory or clinical setting.
Today Caltech announced the appointment of Thomas F. Rosenbaum as the Institute's ninth president. Dr. Rosenbaum is currently the John T. Wilson Distinguished Service Professor of Physics and provost at the University of Chicago.
The industrial technique used to make nitrogen fertilizers mirrors the natural process of nitrogen fixation but requires high heat and pressure. Researchers at Caltech have synthesized a catalyst that allows for nitrogen fixation under much milder conditions.
Now in its sixth year of exploring the intersection between biology and engineering, the Donna and Benjamin M. Rosen Bioengineering Center has chosen Caltech professor Frances Arnold as its new director. Arnold, the Dick and Barbara Dickinson Professor of Chemical Engineering, Bioengineering and Biochemistry began her tenure as director on June 1.
