Welcome to another issue of Research, our annual synopsis of the status of research in
the NC State Computer Science Department. Research is crucial to the success of our
department, and we are pleased to report that research productivity continues to grow, with
annual expenditures reaching a record of more than $14M. And, we currently have more
than $53M in active research grants. This ranks us in the top ten departments for sponsored
research funding among computer science departments in colleges of engineering in the
United States. Some research highlights are below (A list of select representative research
projects appears on page three of this newsletter.):
- NC State is partnering with the National Security Agency (NSA) to create the
Laboratory for Analytic Sciences (LAS). The $60 million lab will bring together
some of the brightest minds from government, academia and industry to address
the most challenging big-data problems; Additionally, the NSA funding for the
Science of Security Lablet (SoSL) has been extended three years;
- NC State is one of three Triangle universities that have received cybersecurity
research awards totaling $3 million from the National Science Foundation (NSF).
NC State will be working with Duke University and UNC-Chapel Hill to develop
new solutions to bolster the security of our digital infrastructure;
- Dr. James Lester and other researchers in the Computer Science Department are
developing interactive software aimed at helping teens reduce alcohol use and the
risks associated with drinking alcohol;
- Dr. Nagiza Samatova is one of nine faculty members in six departments spanning
three colleges that are involved in a five-year, $25 million grant by the National
Nuclear Security Administration’s (NNSA) Office of Defense Nuclear Non-
proliferation Research and Development. The goal of the project is to develop
the next generation of leaders with practical experience in technical fields related
to nuclear nonproliferation;
- Dr. William Enck and other researchers have developed a modification to the core
Android operating system that allows developers and users to take advantage of
new security tools. (Continued on page 2)
Imagine a team of humans, dogs, robots and drones swooping onto the scene in the aftermath of a disaster and working together to find and rescue anyone trapped in collapsed buildings. That’s the goal of a team of researchers from around the US working on what they call the Smart Emer- gency Response System (SERS).
NC State researchers, Drs. David Roberts (pictured here with Diesel) and Alper Bozkurt, have developed a high-tech dog harness equipped with sensors and other devices that will make dogs more effective at collecting information and incorporate the dogs into the larger network of coordinated disaster response.
The harness includes new sensors developed by Bozkurt and Roberts that monitor a dog’s behavior and physiology, such as heart rate. These sensors will allow both dog handlers and the emergency response command center to remotely track a dog’s well-being and to determine if the animal has picked up a scent or found a specific object or area of interest.
Communication technologies on the harness will allow handlers to relay commands to a dog remotely. Bozkurt and Roberts have incorpo- rated audio communication, via speakers, into the vest. However, they think the more reliable remote communication will come via “tactile inputs” – they’re training dogs to respond to gentle “nudges” that come from within the electronic harness itself. “I want to be clear that these are not aversive punishments, but slight, tactile nudges from motors in the vest – like a vibrating cell phone. We’re using exclusively reward-based training techniques,” Roberts says.
Bozkurt, Roberts and the rest of the SERS team participated in the Smart America Challenge event in Washington, D.C., this summer.
