Prof. Campbell Wins The ACM Sensys 2018 Test-of-Time Award

Andrew Campbell and his PhD students received the prestigious ACM SenSys 2018 Test-of-Time Award (10 year award) for their paper: “Sensing meets mobile social networks: the design, implementation and evaluation of the cenceme application”.

In 2008, when the App Store first opened Professor Campbell and his team released the CenceMe app, which implemented a machine learning algorithm directly on the iPhone for the first time to automatically detected the user’s behavior (e.g., sitting, walking, running, socializing). The app pushed this user context to Facebook and for the first time human behavior passively inferred from sensors embedded in smartphones was visible to friends in real-time.

The award citation states: “At the dawn of the smartphone era, this paper had the foresight to realize that smartphones are human companions and their sensors, collectively, can be used to derive novel social behavior insights. It also pioneered applying machine learning across local devices and servers”.

Today, activity recognition is integrated into the operating system of every Android and iPhone.

Graduate Students Create Computer-Chip Security Fix

Dartmouth computer science graduate students are applying their research techniques to fundamental security flaws recently found in nearly every computer chip manufactured in the last 20 years—flaws that they say could prove catastrophic if exploited by malicious hackers.

The researchers are coming to grips with a design flaw that ultimately falls into the province of the chip manufacturers—such industry giants as Intel and AMD. Until new designs are implemented, an interim solution devised at Dartmouth can fill the breach.

The research team includes two PhD students, Prashant Anantharaman and Ira Ray Jenkins, and Rebecca Shapiro, Guarini ’18, who received her PhD this past spring. Professor of Computer Science Sean Smith and Research Associate Professor Sergey Bratus advised the team.

Gabe Weaver Named Inaugural Dieckamp Fellow

Dr. Gabe Weaver received his PhD from Dartmouth in 2013. During his research career, Gabe has had stints at MIT’s Lincoln Laboratory and as a non-residential fellow at Harvard, where he designed an XML vocabulary to encode Ancient Greek Mathematical diagrams. He more recently worked as a research scientist in Illinois' Information Trust Institute.

For his dissertation at Dartmouth College, Gabe created eXtended Unix tools (XUTools) to process a broader class of languages in which security-policies are expressed in the language-theoretic sense. XUTools allows practitioners to extract, count, and compare files in terms of high-level language structures found in modern markup, programming, and configuration languages. Articles on XUTools have been featured in news outlets such as ComputerWorld, CIO Magazine, Communications of the ACM, and Slashdot.

Students win "Best Cyber Security Solution" award

Congratulations to PhD student Jason Reeves and undergrad Chris Frangieh, whose poster “TEDDI: Tamper Detection on Distributed Infrastructure” (based on Jason's thesis research) was voted one of two "Best Cyber Security Solutions" by Advanced Cyber Security Center Annual Conference attendees in November 2015.

Jason's work is part of the Department of Energy's Cyber Resilient Energy Delivery Consortium, of which Dartmouth is a member.

Explorations in Rapid Prototyping

COSC 89/189 Computational Fabrication was offered for the first time this Fall at Dartmouth, taught by Professor Emily Whiting. The course provided an in-depth study of 3D printing technology and cutting-edge research in computational methods for 3D design.

To culminate the term students presented independent design projects. The inventive array of products featured tileable gear art, smart gloves playing rock-paper-scissors, 3D mazes as light installation, a mobile app to create and simulate pop-ups, and much more. Students benefited from prototyping resources across campus including the Thayer School Machine Shop, Woodworking Shop and the Fabrication Lab in Sudikoff.

The DALI Lab and DEN Partner for The Pitch

The Pitch is a chance for members of the Dartmouth community to share their ideas, research, and innovations in hopes of receiving venture, design, development, and/or funding support. Each project has two minutes to share their project proposal with a panel of live judges from the Digital Arts Leadership and Innovation Lab (DALI), DEN, and a live audience. Winners of The Pitch will be chosen by both the judges and the audience.

The Pitch presents a unique opportunity for people to learn how their ideas and innovations can become a reality with the support of their community members and peers.

The Pitch will take place on Tuesday, November 4 from 5:00-6:30 PM in Loew Theater in the Black Family Visual Arts Center. Whether you're pitching your idea or interested in what others are presenting, we hope you'll join us to vote in the Pitch!

 

Graduate Teaching Award: Travis Peters

Travis Peters, a doctoral student in the Department of Computer Science, was selected as one of this year’s recipients of the Graduate Student Teaching Award.

Peters will be starting his second year as a PhD student this fall. While at Dartmouth, he has had the opportunity to work with Professor David Kotz on two different projects. This past winter, Peters began working on the development of a mobile health intervention application (or “app”) and wearable sensor for the Center for Technology and Behavioral Health (CTBH). The purpose of this invention is ultimately to aid people battling smoking addiction and cigarette cravings. The pilot study to test this app and sensor is slated to begin over the summer.

Navigating the Path Between Computer Science and Music

Dana Cook Grossman

In 1959, the British novelist and physicist Sir C.P. Snow gave a famous lecture ruing what he saw as a rift between society’s “two cultures”—the humanities and the sciences. Snow would surely be heartened, half a century later, by Dartmouth doctoral student Andy Sarroff. “I have one foot in the music department and one foot in the computer science department,” says Sarroff.

“I would describe myself as being in the field of music-information retrieval,” he continues. “It’s not such an old field—probably just about 15 years old. Its focus is taking music in whatever format it’s in and extracting meaningful information out of it. Usually, I’m working with digital audio—looking at the zeros and ones in digital audio and mapping the perception to the signal.”

Sarroff came to his interest in “zeros and ones” through his interest in notes and meter.

“Music was a gateway to computing for me. I’ve always played music,” he says.

He was a music major as an undergraduate at Wesleyan and then a recording engineer for eight years or so. He went on to earn a master’s degree in music technology at New York University.
