President Rosenbaum Highlights Postdocs as "Unsung Heroes"

09-24-18

In a letter to the Caltech community during National Postdoc Appreciation Week, the Caltech President emphasizes the role this key group plays at the Institute. He stated, “Caltech's mission of world-leading research and education depends crucially on our postdoctoral scholars. Although their time at Caltech may be short, they quickly become vital parts of the Institute's intellectual fabric.” [President’s Letter] [EAS Postdoc Resource Page]

Graduate Student Wins AAAS Mass Media Fellowship

04-30-18

Giuliana Viglione, a graduate student in Professor Andrew Thompson’s group and a member of the first E111 class has been selected to join the 2018 American Association for the Advancement of Science (AAAS) Mass Media Science & Engineering Fellows Program. The fellows are placed at media organizations nationwide and trained to sharpening their abilities to communicate complex scientific issues to the public. In her research, Giuliana uses robots to investigate small-scale motions in the ocean and what their effect on climate may be.  She will be spending the summer working at King5, an NBC affiliate in Seattle, where she will use her expertise to report on the effects of climate change in the Pacific Northwest.

Scientists Discover Unexpected Side Effect to Cleaning Up Urban Air

12-19-17

For decades, efforts to reduce air pollution have led to cleaner air in U.S cities like Los Angeles, with subsequent improvements in public health. Those efforts have targeted both nitric oxides and hydrocarbons. Hydrocarbons are emitted from many sources including gasoline-powered cars, trucks, solvents, cleaners used both at home and in industrial settings, and even trees.  Professor Paul O. Wennberg and colleagues have found that there is another chemical pathway for forming organic hydroperoxides—one that occurs at nitric oxide levels substantially higher than can be found in the atmosphere over unpopulated regions. "This is chemistry that does not exist in any of the models of how nitric oxide and hydrocarbons interact," says Professor Wennberg. [Caltech story]

Capturing Clouds

07-12-17

Professor Tapio Schneider has helped bring artist Karen LaMonte's cloudy vision to life. "I thought it was a great idea," says Schneider, whose work focuses on reducing uncertainties in climate change projections—in part through modeling cloud formation to better understand clouds' impact on the environment. Collaborating with LaMonte, he reasoned, could help raise awareness of these issues. "Clouds are hugely important for the climate," says Schneider. "How much warmer it will get depends on what happens to cumulus clouds like those Karen was interested in. " [SoCaltech story]

123rd Commencement Ceremony

06-19-17

Caltech’s 123rd commencement ceremony was held on Friday June 16, 2017. The commencement speaker was Mae Jemison, an engineer, physician, and NASA astronaut. Looking up, she said, allows us to remember that there is more that connects us than divides us. "Connection to the greater universe is something I hope for you throughout your lives. Never forget to look up and keep the bigger picture in mind. Look up at the sky, the moon, the stars when you need to recharge. Let the gravity of Earth give you a warm hug when you're feeling low. Look up to remember what inspires you. Keep the sparkle in your eyes, keep it long past graduation." [Caltech story]

Professor Wennberg Elected to the National Academy of Sciences

05-02-17

Paul O. Wennberg, R. Stanton Avery Professor of Atmospheric Chemistry and Environmental Science and Engineering, as been elected to the National Academy of Sciences in recognition of his distinguished and continuing achievements in original research. His work applies traditional physical chemistry techniques to study the mechanisms of chemical transformation in the earth's atmosphere and in the carbon cycle. This research has helped create the Total Carbon Column Observing Network, which measures the distribution of greenhouse gases across the globe. [Caltech release]

Tools and Techniques to Track and Study Methane

01-19-17

Methane is less prevalent in the atmosphere than fellow greenhouse gas carbon dioxide (CO2), but it presents more difficult challenges for researchers attempting to study it. Professor Wennberg, is working with colleagues from across Caltech to study methane and its effects on the globe and to pioneer tools and techniques needed to identify, track, and characterize the gas and its sources. One such colleague is Professor Vahala who has paved the way for the miniaturization of high-resolution spectrometers. His new soliton-based system is the basis for a new collaboration with Professor Frankenberg to apply dual-comb spectrometer to methane tracking and analysis. [Caltech story]
