Two Young ECE Researchers Awarded Presidential Career Awards

Two Duke University engineers have received the highest honor given to scientists by the U.S. government. Adrienne Stiff-Roberts and Chris Dwyer, both assistant professors of electrical and computer engineering at Duke’s Pratt School of Engineering, each received a Presidential Early Career Award [...]

Writing in Air Is Not Pie in the Sky

It's a familiar scene in airports and train stations. Hands full with luggage, briefcase, laptop or coat and there’s something you need to remember, like the level and row numbers where you parked your car in the deck. What do you do? Instead of relying on your memory, or finding a place to put all [...]

Young Electrical Engineer Honored for Research

When Adrienne Stiff-Roberts decided during her high school career that she wanted to be a scientist, and then an engineer, she didn’t know that she’d end up manipulating the exotic properties of quantum mechanics to perfect devices ranging from infrared cameras to solar cells. It’s not surprising [...]

Next Generation Cloaking Device Demonstrated

A device that can bestow invisibility to an object by “cloaking” it from visual light is closer to reality. After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team of Duke University engineers have produced a new type of cloaking device, [...]

Tiny Lasers, Big Advances

While an undergraduate in the early 1980s at Creighton University in Omaha, Neb., Nan Jokerst thought lasers were so cool she should build one herself. Using plans from a Scientific American article, she did just that in the basement of the physics building. "It worked, amazingly enough," she says [...]

Harnessing Lightning and Hiding from Sound

Steve Cummer jokingly calls himself something of a Luddite because of his stubborn refusal to give up pencil and paper as his main medium for working through ideas. But in reality, that quirk is hardly enough to justify such a title, particularly when you consider that some of those ideas he [...]

Creating the Future of Mobile Computing

Like most users, Romit Roy Choudhury enjoys the freedom, information, and options his iPhone and other devices provide, but for him these instruments serve a more important role as research tools that help him envision future innovations in mobile computing. Roy Choudhury's academic life is [...]

Senior Wins Marshall Scholarship

Dan Roberts, a Pratt School of Engineering student involved in research that created such unconventional electromagnetic devices as an "invisibility cloak" will receive one of 40 Marshall Scholarships offered for the 2009-10 academic year. Roberts, a senior from Melville, N.Y., is the 19th Marshall [...]

A New Paradigm in Electrical Sensing

When a snake is cut in half, it dies. This illustrates how electrical devices can respond to damage. Since they are at their core closed circuits, devices will fail whenever the circuit is interrupted. However, if these devices could be more like earthworms, intriguing new possibilities arise. [...]

Searching for Genes, Photo Files, and Landmines — In Haystacks

Lawrence Carin's graduate training was in electromagnetics and wave analysis-- a fitting choice for someone who remembers trying to assemble and plug in electronic contraptions as a five year old and who grew up tinkering with radios and motors. Overall, his life was fairly standard preparation for [...]
