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.

Sisca

Solar Powered, Electrochemical, Wastewater Treatment System

12-18-15

Cody Finke, Environmental Science and Engineering graduate student, and Justin Jasper, Resnick Sustainability Institute Prize Postdoctoral Scholar, are the runner ups for the Dow Resnick Sustainability Innovation Student Challenge Award (SISCA) at Caltech. They have been working Professor Michael Hoffmann to enhance a modular, solar powered, electrochemical, on-site wastewater treatment system created by their group for toilets in the developing and developed world. With an operating cost of less than 5 US cents per day, this wastewater treatment technology meets benchmarks for affordability in the developing world. It also has the potential to protect human health and ecosystem well-being in communities most at risk to disease and resource-loss through environmental pollution. [Resnick Institute story]

Extending a Battery's Lifetime with Heat

10-03-15

The research of alumnus Asghar Aryanfar (’15 PhD, ME) along with Professors Goddard and Hoffmann has shown that heat can break down the damaging branch-like structures that grow inside batteries, which may possibly be used to extend battery lifetimes. [Learn more] [Read the paper]
