Modular Space Telescope Could Be Assembled By Robot 09-28-16

Professor Sergio Pellegrino and colleagues including Professor Joel Burdick, are proposing a space observatory with a 100 meters diameter primary mirror. Their design calls for the use of more than 300 deployable truss modules that could be unfolded to form a scaffolding upon which a commensurate number of small mirror plates could be placed to create a large segmented mirror. In this concept, a spider-like, six-armed "hexbot" would assemble the trusswork and then crawl across the structure to build the mirror atop it. [Caltech story]

James J. Morgan Symposium 09-23-16

On Friday September 23rd, 2016 the Environmental Science and Engineering Department hosted a day-long tribute to James J. Morgan, Marvin L. Goldberger Professor of Environmental Engineering Science, Emeritus. The symposium featured a series of presentations by his former students and leaders in the field of aquatic chemistry. Professor Morgan’s teaching and research centered on aquatic chemistry; major themes comprised rates of abiotic manganese oxidation on particle surfaces and flocculation of natural water particles, and chemical speciation proved the key. He came to Caltech as Associate Professor of Environmental Health Engineering in 1965 and became the Goldberger Professor of Environmental Engineering Science in 1987. He has served Caltech in a variety of capacities including Academic Officer for Environmental Engineering Science, Dean of Students, Executive Officer for Environmental Engineering Science, Acting Dean of Graduate Studies, and Vice President for Student Affairs.

Professors Newman and Orphan Named MacArthur Fellows 09-21-16

Environmental Science and Engineering Professors Dianne Newman and Victoria Orphan have been selected as 2016 MacArthur Fellows. Professor Newman's research focuses on microbial stress responses, with an emphasis on mechanisms of energy generation and survival when oxygen is scarce. Professor Orphan studies the molecular microbial ecology of anaerobic communities with a particular focus on microorganisms that live in deep-ocean sediment beds and consume large quantities of methane released from seeps in the ocean floor.
