"Information Security War Room" at USENIX Security

Sergey Bratus and Felix 'FX' Lindner delivered a joint invited talk at this year's USENIX Security Conference. This premier conference brings together attendees from academia, industry, and government.

The talk entitled "Information Security War Room" examined the state of IT security, the implications of the ongoing computer insecurity epidemic for national security and "cyberwarfare", the current misguided attempts of various governments to regulate research into computer attacks, and the strategic options the computer security community has left to revert the current trend of ubiquitous insecurity, and to make practical progress towards computers we could finally trust.

The talk received considerable attention; slides posted online got over 30,000 download requests to date.

CS students phone in their feelings

Much of the stress and strain of student life remains hidden. The StudentLife study led by Professor Andrew Campbell built a smartphone sensing app that 48 computer science students used over 10 weeks of the spring term 2013. It revealed a number of interesting findings.  Researchers found that objective sensing data from the students' phones significantly correlated with academic performance and mental-health, such as, grades, GPA, stress, loneliness, depression and flourishing.

The study captured behavioral trends across the Dartmouth term. For example, students returned from spring break feeling good about themselves, relaxed (i.e., low stress levels), sleeping well and going to the gym regularly. That all changed once the Dartmouth term picked up speed toward midterm and finals, as shown in the plot.

Lorenzo Torresani wins the Google Faculty Research Award

Our own Lorenzo Torresani has won the Google Faculty Research Award. Dr. Torresani aims to use deep learning (i.e., learning of deep networks) to discover compact representations of video that work well for classifying human pose dynamics.

Dr. Torresani proposed to learn semantic primitives to represent human actions in video. The primitives are learned by training deep convolutional neural networks to classify different human pose dynamics. Such learned representation promises to significantly improve the accuracy of video understanding applications, including action recognition, semantic segmentation of video, as well as search and retrieval.

The technical novelty of the approach is twofold:

Three new faculty joining CS

Three new faculty members are joining the Computer Science department--Emily Whiting, Wojciech Jarosz, and Qiang Liu. Emily Whiting will be on campus starting this coming Fall 2014, and Wojciech Jarosz and Qiang Liu will join us in the Fall of 2015.

Emily Whiting completed her postdoctoral training at ETH Zurich, prior to which she received both M.Sc. and Ph.D. degrees from MIT. Her research interests include architectural geometry, masonry structures, procedural modeling, computer-aided design, and 3D fabrication.

Wojciech Jarosz comes to us via Disney Research, Zürich, where he has been a Senior Research Scientist. His work has aimed to understand "why things look the way they do," how interaction between light and objects can be simulated efficiently, and how physical objects can be created with control over their appearance.

Prof. Bratus Tackles Ubiquitous Internet Insecurity

Dartmouth’s Sergey Bratus is on a mission to protect the Internet from cyber attacks and other criminal enterprises. It’s a big job.

Among his concerns about what he calls the “ubiquitous Internet insecurity” are credit card and identity theft and other misuses of the information highway. “We also hear reports of Internet infringement by repressive regimes targeting computers and smartphones of dissidents and protesters across the world,” says Bratus, a research assistant professor in the Department of Computer Science.

Drs. Zhou and Campbell win Google Faculty Research Award

Prof. Xia Zhou and Prof. Andrew Campbell won Google Faculty Research Award (http://research.google.com/university/relations/research_awards.html) for their work on boosting Wi-Fi energy efficiency for smart devices. Their proposed work centers on a simple yet highly effective architectural change to today’s smart devices, which holds the potential to achieve significant energy saving while maximizing Wi-Fi connectivity.

“The Grassy Knoll Revisited” Probes Chaos of JFK’s Death

Dennis Grady can still remember his teachers freaking out and recall coming home to his distraught parents on the day President John F. Kennedy was assassinated in Dallas.

“It occurred to me the people who are students now were about that age when 9/11 happened,” says Grady, exhibits designer with Dartmouth Library Education & Outreach. “Everything you assumed about the way the world worked was turned upside down.”

Grady samples this raw, destabilizing uncertainty in “The Grassy Knoll Revisited: On the Anniversary of the Assassination of JFK,” an exhibition drawn from the holdings of Baker-Berry Library and Rauner Special Collections Library.

“On November 22, 1963, at 12:30 p.m. Central Standard Time, President John F. Kennedy was assassinated in Dallas, Texas, by Lee Harvey Oswald/anti-Castro Cubans/the Mafia/the CIA/the FBI/the Secret Service/the KGB/LBJ,” writes Grady in his introduction to the exhibition.

Harnessing Smartphones to Prevent Psychosis

There is no known cure for schizophrenia, but Dartmouth’s Dror Ben-Zeev and his team are working on ways to help those who suffer from it. The disease is chronic, often fluctuating between psychotic episodes and periods of remission.

“We are developing a mobile system that can detect early warning signs of impending episodes, and trigger time-sensitive interventions that may help prevent relapses into psychosis,” says Ben-Zeev, a clinical psychologist, an assistant professor of psychiatry at the Geisel School of Medicine and a researcher at the Dartmouth Psychiatric Research Center.

Schizophrenia is a serious mental disorder that many have come to know about through actor Russell Crowe’s portrayal of Nobel Laureate John Nash in the movie A Beautiful Mind. People with schizophrenia may hear voices, see things that aren’t there, fear they are in danger, and suffer other debilitating symptoms. It is typically treated with medication supported by psychotherapy, but Ben-Zeev says this may be insufficient for several reasons.

Dartmouth IT Security Institute Gets New Leadership

Office of Public Affairs

Professor of Computer Science Sean Smith is assuming the leadership of Dartmouth’s Institute for Security, Technology, and Society (ISTS). The institute is dedicated to pursuing research and education to advance information security and privacy throughout society.

The torch has been passed to him by Denise Anthony, associate professor of sociology and director of ISTS since 2008. “I can move on from my position as director knowing that it is in Sean’s capable hands,” says Anthony. “Sean is a leading thinker in computer security and privacy research, and he is also an excellent teacher and collaborator who embodies the mission of ISTS.”

Anthony is embarking on a nine-month sabbatical and will continue to be involved in collaborative research projects through ISTS focused on privacy and healthcare IT as well as efforts to promote STEM education and career opportunities for women and minorities.
