Professor Victoria Orphan Named Member of AAAS


Victoria J. Orphan, James Irvine Professor of Environmental Science and Geobiology and the director of the Center for Environmental Microbial Interactions (CEMI), has been honored as a new member of the American Academy of Arts and Sciences (AAAS). Orphan focuses on communities of microbial life involved in the cycling of elements such as sulfur, carbon, and nitrogen. She has spent decades studying the partnership of a species of bacteria and a species of archaea that live within deep-sea methane seeps in what is called a consortia, a kind of symbiotic aggregate of multiple species.

International Alliance of Universities Addressing Climate Change


Caltech has joined dozens of universities around the globe in launching the International Universities Climate Alliance (IUCA). The alliance is a network of fourty universities in eighteen countries, each with different strengths in analyzing and addressing climate change. "The IUCA hopes to be a resource to governments and other stakeholders that provides an independent and respected international voice on matters related to climate science, impacts, mitigation, and adaptation," says Andrew Thompson, Professor of Environmental Science and Engineering.

A Third of California Methane Traced to a Few Super-Emitters


Professor Christian Frankenberg, Professor of Environmental Science and Engineering, Jet Propulsion Laboratory Research Scientist, is helping California create a detailed, statewide inventory of methane point sources. The new data can be used to target actions to reduce emissions of this potent greenhouse gas. "This work shows unequivocally that methane point sources not only exist in the oil and gas industry but also in landfills and agriculture. Finding these large point sources is the trickiest part; mitigation can ensue quickly after that, representing a win-win for both the environment as well as industry," says Frankenberg.

Jing Li Receives AAAR Sheldon Friedlander Award


Jing Li, a postdoctoral scholar working with Professor Michael R. Hoffmann, is the recipient of the 2019 Sheldon K. Friedlander Award from the American Association of Aerosol Research (AAAR). The award recognizes an outstanding dissertation by an individual who has earned a doctoral degree in any discipline related to the physical, biomedical or engineering sciences in the field of aerosol science and technology. In her doctoral thesis, Jing focused on studying the global PM-borne biologicals and their toxicity, more broadly in bioaerosol field. Her dissertation work raises the awareness of airborne transmission of antibiotic resistance genes (ARGs), as well as global differences of local source-specific PM toxicity. [Past recipients]

Luis Phillipe Tosi Receives 2019 Richard B. Chapman Memorial Award


Luis Phillipe Tosi, a graduate student working with Professor Tim Colonius, is a recipient of the 2019 Richard B. Chapman Memorial Award. His doctorate research focuses on experiments, numerical simulations, and modeling to understand fluid-structure instabilities that make flow energy harvesting devices possible. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.

New Climate Model to Be Built from the Ground Up


"Projections with current climate models—for example, of how features such as rainfall extremes will change—still have large uncertainties, and the uncertainties are poorly quantified," says Professor Tapio Schneider, principal investigator of the Climate Modeling Alliance (CliMA). "For cities planning their stormwater management infrastructure to withstand the next 100 years' worth of floods, this is a serious issue; concrete answers about the likely range of climate outcomes are key for planning." The new climate model will be built by a consortium of researchers led by Caltech, in partnership with MIT; the Naval Postgraduate School (NPS); and JPL, which Caltech manages for NASA. It will use data-assimilation and machine-learning tools to improve itself in real time, harnessing both Earth observations and the nested high-resolution simulations. "The success of computational weather forecasting demonstrates the power of using data to improve the accuracy of computer models; we aim to bring the same successes to climate prediction," says Professor Andrew Stuart.

President Rosenbaum Highlights Postdocs as "Unsung Heroes"


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


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.
