Abbas El Gamal is the Hitachi America Professor in the School of Engineering and the Fortinet Founders Chair of the Department of Electrical Engineering. He has been awarded the 2016 IEEE Richard W. Hamming Medal. The award's citation reads, "for contributions to network multi-user information theory and for wide ranging impact on programmable circuit architectures."

IEEE Medals are the highest awards that the IEEE presents on behalf of the IEEE Board of Directors. The IEEE Richard W. Hamming Medal recognizes exceptional contributions to information sciences, systems, and technology. Established in 1986, the medal is named in honor of Dr. Richard W. Hamming, who had a central role in the development of computer and computing science, and whose many significant contributions in the area of information science include his error-correcting codes.

Professor El Gamal is a Life Fellow of IEEE and member of the NAE. He received the Claude E. Shannon Award in 2012.

Abbas El Gamal’s lasting contributions to information theory, wireless networks, field programmable gate arrays (FPGAs), and digital imaging have immensely impacted a wide variety of information technology applications critical in today’s society. His early work formed the basis for several new areas in multi-user information theory, paving the way to capacity results integral to today’s communications networks. He determined the capacity of the product of Gaussian broadcast channels and of deterministic interference channels leading to recent advances in multi-antenna and interference-limited wireless networks. Together with Thomas Cover, he established the first upper and lower bounds on the capacity of the three-node relay network. This work introduced the cut-set upper bound for networks, which is widely used in information theory today, as well as the compress-forward and decode-forward schemes, which continue to be the dominant relaying techniques. His recent work has involved the creation of coding schemes for sending multiple sources over noisy networks, and significant contributions to wireless networks through characterizing their optimal delay-throughput tradeoff and devising schemes for energy-efficient packet transmission scheduling. His book Network Information Theory (Cambridge Press, 2011) with Young-Han Kim provides the first unified and comprehensive coverage of the field. El Gamal’s contributions to hardware design include the development of integrated circuit fabrics and tools that significantly reduce design time and cost of systems used in computing, communication, and signal-processing applications. In 1986, he co-founded Actel, where he co-invented the routing architecture used in all commercial FPGAs today. He subsequently pioneered the use of FPGAs in teaching digital system design, which has become standard in all electrical engineering programs. (From IEEE Richard W. Hamming Medal Recipients)

Professor Arbabian and research professo Khuri-Yakub's research was spurred by a challenge posed by the Defense Advanced Research Projects Agency (DARPA), best known for sponsoring the studies that led to the Internet. DARPA sought to develop a system to detect plastic explosives buried underground – improvised explosive devices (IEDs) – that are currently invisible to metal detectors. The task included one important caveat: The detection device could not touch the surface in question, so as not to trigger an explosion.

Professor Arbabian and research professor Khuri-Yakub detail their latest step toward developing such a device through experiments, which are detailed in Applied Physics Letters and presented at the International Ultrasonics Symposium in Taipei, Taiwan.

The work grows out of research designed to detect buried plastic explosives, but the researchers said the technology could also provide a new way to detect early stage cancers.

"We've been working on this for a little over two years," Khuri-Yakub said. "We're still at an early stage but we're confident that in five to ten to fifteen years, this will become practical and widely available."


The research team includes graduate students Hao Nan, Kevin Boyle, Nikhil Apte, Miaad Aliroteh, Anshuman Bhuyan and senior research associate Amin Nikoozadeh.

Recent articles published by EE Professors Eric Pop and H.S. Philip Wong describe advances in memory and data storage using graphene. The three experiments demonstrate post-silicon materials and technologies that store more data per square inch and use a fraction of the energy of today's memory chips.

The unifying thread in all three experiments is graphene, an extraordinary material isolated a decade ago but which had, until now, relatively few practical applications in electronics.

"Graphene is the star of this research," said Eric Pop, associate professor of electrical engineering and a contributor to two of the three memory projects. "With these new storage technologies, it would be conceivable to design a smartphone that could store 10 times as much data, using less battery power, than the memory we use today."

Professor H.-S. Philip Wong and Pop led an international group of collaborators who describe the graphene-centric memory technologies in separate articles in Nature Communications, Nano Letters, and Applied Physics Letters.

"Data storage has become a significant, large-scale consumer of electricity, and new solid-state memory technologies such as these could also transform cloud computing," Wong said.

Pop and Wong agree that these studies show that graphene is far from a laboratory curiosity. The material's unique electrical, thermal and atomically thin properties can be utilized to create more energy-efficient data storage. Such properties do not exist in the silicon world, yet could potentially transform the way we store and access our digital data in the future.

EE Professor Shanhui Fan, research associate Aaswath P. Raman, and doctoral candidate Linxiao Zhu describe their research in the current issue of Proceedings of the National Academy of Sciences.

The group's discovery, tested on a Stanford rooftop, addresses a problem that has long bedeviled the solar industry: The hotter solar cells get, the less efficient they become at converting the photons in light into useful electricity.

Their solution is based on a thin, patterned silica material laid on top of a traditional solar cell. The material is transparent to the visible sunlight that powers solar cells, but captures and emits thermal radiation, or heat, from infrared rays.

"Solar arrays must face the sun to function, even though that heat is detrimental to efficiency," Fan said. "Our thermal overlay allows sunlight to pass through, preserving or even enhancing sunlight absorption, but it also cools the cell by radiating the heat out and improving the cell efficiency."

In 2014, the same trio of inventors developed an ultrathin material that radiated infrared heat directly back toward space without warming the atmosphere. They presented that work in Nature, describing it as "radiative cooling" because it shunted thermal energy directly into the deep, cold void of space.

In their new paper, the researchers applied their previous work to improve solar array performance when the sun is beating down.

The Stanford team tested their technology on a custom-made solar absorber – a device that mimics the properties of a solar cell without producing electricity – covered with a micron-scale pattern designed to maximize the capability to dump heat, in the form of infrared light, into space. Their experiments showed that the overlay allowed visible light to pass through to the solar cells, but that it also cooled the underlying absorber by as much as 23 degrees Fahrenheit.

The Information Processing Society of Japan (IPSJ) presented their Funai Achievement Award to Professor Bill Dally, recognizing his accomplishments in computer architecture, particularly in the areas of parallel computing and Very Large Scale Integration processing. The IPSJ noted that Dally has made major contributions in education at the Massachusetts Institute of Technology, Stanford University, and in industry as NVIDIA's chief scientist.

Dally is the first non-Japanese scientist to receive the award since the first two awards were given out in 2002 to Alan Kay (a pioneer in personal computing) and in 2003 to Marvin Minsky (a pioneer in artificial intelligence).

"I'm honored to be selected for one of the world's major prizes in computer science. It's particularly rewarding to be in the company of computer science luminaries like Alan Kay and Marvin Minsky," said Dally, who received the award at an IPSJ event in Matsuyama, Japan. "I'm grateful to the IPSJ for acknowledging the importance of my research in parallel computing."

Professor Shuichi Sakai, dean of the Computer Science Department at the University of Tokyo, said, "Bill Dally has always been a revolutionary rather than a revisionist in computer science."

Dally's achievements across more than 30 years of work and research include developing the system and network architecture, signaling, routing and synchronization technology found in most large parallel computers today. He also introduced the Imagine processor, which employs stream processing architecture, providing high performance computing with power, speed and efficiency.

Prior to joining NVIDIA in 2009, Dally served as chairman of Stanford's Computer Science department from 2005-2009, where he taught beginning in 1997. Previously, he led the group at MIT that built the J-Machine and M-Machine, parallel machines that pioneered the separation of mechanism from programming models.

The first fully internal method of delivering optogenetics has been established. Miniature implanted devices are being wirelessly powered by a special power source that transmits frequencies that resonate in certain lab mice.

The device dramatically expands the scope of research that can be carried out through optogenetics to include experiments involving mice in enclosed spaces or interacting freely with other animals. The work is published in the Aug. 17 edition of Nature Methods.

Professor Ada Poon states, "This is a new way of delivering wireless power for optogenetics. It's much smaller and the mouse can move around during an experiment." See video.

The device can be assembled and reconfigured for different uses in a lab, and the design of the power source is publicly available. "I think other labs will be able to adapt this for their work," Poon said.

This novel way of delivering power is what allowed the team to create such a small device. And in this case, size is critical. The device is the first attempt at wireless optogenetics that is small enough to be implanted under the skin and may even be able to trigger a signal in muscles or some organs, which were previously not accessible to optogenetics.

The team says the device and the novel powering mechanism open the door to a range of new experiments to better understand and treat mental health disorders, movement disorders and diseases of the internal organs. They have a Stanford Bio-X grant to explore and possibly develop new treatments for chronic pain.

Professor Poon's lab recently sponsored a summer program for local female high school students, providing them a chance to explore several introductory concepts of EE. View article.
