Dabiri Receives Waterman Award from the National Science Foundation

08-05-20

The National Science Foundation (NSF) honors John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, with the 2020 Alan T. Waterman Award. The Alan T. Waterman Award is given to an outstanding young U.S. scientist or engineer along with a medal and other recognition. "This year's scientific pioneers are innovators who are creatively addressing some of the most challenging scientific questions," said NSF Director Sethuraman Panchanathan. "John Dabiri has looked to the fluid mechanics of sea life for inspiration to build better wind farms that appear to boost efficiency with a much smaller footprint." [NSF story] [Caltech story

Bionic Jellyfish Swim Faster and More Efficiently

01-30-20

John Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, has developed a tiny prosthetic that enables jellyfish to swim faster and more efficiently than they normally do, without stressing the animals. Dabiri is envisioning a future in which jellyfish equipped with sensors could be directed to explore and record information about the ocean. "Only five to 10 percent of the volume of the ocean has been explored, so we want to take advantage of the fact that jellyfish are everywhere already to make a leap from ship-based measurements, which are limited in number due to their high cost," Dabiri says. "If we can find a way to direct these jellyfish and also equip them with sensors to track things like ocean temperature, salinity, oxygen levels, and so on, we could create a truly global ocean network where each of the jellyfish robots costs a few dollars to instrument and feeds themselves energy from prey already in the ocean."

Caltech's Unique Wind Projects Move Forward

06-10-13

John O. Dabiri, Professor of Aeronautics and Bioengineering, has big plans for a high school in San Pedro, military bases in California, and a small village on Bristol Bay, Alaska. "We have been able to demonstrate that using wind turbines that are 30 feet tall, as opposed to 300 feet tall, could generate sufficient power for wind-farm applications," Dabiri says. "One of the areas where these smaller turbines can have an immediate impact is in the military." The Office of Naval Research is funding a three-year project by Dabiri's group to test the smaller vertical-axis wind turbines (VAWTs) and to further develop software tools to determine their optimal placement. "We believe that these smaller turbines provide the opportunity to generate renewable power while being complementary to the ongoing activities at the base," Dabiri explains. [Learn More]

A Tissue-engineered Jellyfish with Biomimetic Propulsion

07-23-12

Graduate student Janna C. Nawroth, working with Professor John Dabiri and colleagues at Harvard, has turned solid element—silicon—and muscle cells into a freely swimming jellyfish.

"It is fascinating to witness the evolution of the Dabiri group's research from their initial ground-breaking work in understanding the fluid dynamics of jellyfish propulsion to the building of these complex engineered systems using biological materials," says Chair Ares Rosakis.
