Ginger Clayton receives Staff Career Achievement Award

Virginia Clayton, retired business manager in the Department of Computer Science, has received the university’s 2015 Staff Career Achievement Award. Clayton retired from the university in August 2015 after 30 years of service.

Created in 2011 to recognize retiring staff members, the Staff Career Achievement Award is presented annually to as many as five individuals who have distinguished themselves through exemplary performance and service during their university careers. Nominees must have worked a minimum of 10 years at Virginia Tech. Each recipient is awarded $1,000 cash prize.

As business manager for the Department of Computer Science, Clayton used her fiscal expertise to help navigate budget cuts, pay back departmental loans, initiate and design the faculty grant incentives program, as well as to pass both external and internal audits successfully.
The grant incentives program rewards faculty members who received larger research grants, with incentive awards of increasing magnitude for larger grants. As a result, research funding saw an increase from $20 million to $43.4 million in six years. Clayton’s fiscal and facilities responsibilities directly related to her support in an increasingly high caliber of faculty and graduate student research.

Clayton was considered the “go to” person in the department, as well as in the College of Engineering, among other business managers on campus, and the Office of Special Projects. She was known for her ability to solve problems without hesitation.

Alongside her work within the Department of Computer Science, she also served on the Total Quality Management Team and Steering Committee for University Research for more than two years. Clayton was also a member of the Virginia Society of Research Administrators.

A Sharper Sense of Self: Probabilistic Reasoning of Program Behaviors for Anomaly Detection with Context Sensitivity

Danfeng (Daphne) Yao’s paper was recently accepted to present at the IEEE DSN conference. The 46th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN) will take place in Toulouse, France on June, 2016.

The work of Professor Yao, in collaboration with Kui Xu, Ke Tian and Barbara Ryder, presents a security monitoring system for ensuring the normal executions of complex programs and providing early detection of attacks. Their solution is based on hidden Markov model (HMM) and context-sensitive program analysis. This program-aware HMM model is new. It enables them to achieve unprecedented ultra-low false alarm rates in probabilistic program anomaly detection. Experiments show that their system has up to two orders of magnitude improvement of accuracy over state-of-the-art techniques on average. This project is supported by the Office of Naval Research.

Danfeng (Daphne) Yao is an associate professor and L-3 Faculty Fellow in the Department of Computer Science. The first author Kui Xu is a Ph.D. graduate from Dr. Yao’s group and is currently a security engineer at Amazon, Inc. Ke Tian is a third year Ph.D. student in Yao’s group. Ke Tian will intern at Qualcomm this summer researching on mobile malware detection. Barbara Ryder is the J. Byron Maupin Professor of Engineering and former CS department head.

T. M. Murali and Shiv Kale present new method to reconstruct signaling pathways

Understanding the nature of signaling pathways — networks of molecules in a cell that work together to control a cell’s response to its environment — is an increasingly important part of biomedical research and helpful, for example, in enhancing our understanding of how cancer cells live or die.

In a paper, Pathways on demand: automated reconstruction of human signaling networks, published in Systems Biology and Applications, a Nature partner journal, T. M. Murali, professor in the Department of Computer Science at Virginia Tech, in collaboration with Shiv Kale, a research scientist at the Biocomplexity Institute of Virginia Tech, present a new computational algorithm called PathLinker that automatically reconstructs signaling pathways from a background network of molecular interactions.

SIGCSE 2016

SIGCSE 2016, the flagship conference on computer science education, took place in Memphis TN in March, with a big collection of Virginia Tech students, faculty, and alumni taking on a variety of important roles. My grad student Mohammed Seyam and I presented a paper on teaching mobile software development with Pair Programming. Cliff Shaffer and his students and alums had multiple papers and exhibits. Greg Kulczycki served on a panel.  And, most notably, Steve Edwards was program co-chair this year!

Mohammed Seyam’s paper and talk focused on Teaching Mobile Development with Pair Programming. It explored his investigation of Pair Programming (PP) when teaching mobile software design in an upper level CS course. PP has been shown to be useful in some teaching situations, but Mohammed is the first to look at it in teaching mobile. He also had an entry in the graduate Student Research Competition that took a broader look at the balance between PP, hands-on activities, and traditional lectures when teaching mobile software design, for which he was named a finalist.

As always, SIGCSE featured interesting and engaging keynotes. John Sweller talked about the impacts of cognitive load theory on CS education. Barbara Boucher Owens and Jan Cuny received service awards from SIGCSE and gave keynotes that reflected their life experiences. It was particularly good to see Jan Cuny receive an award given her contributions to diversity in leading broadening participation in computing programs at the NSF. Karen Lee Ashcraft talked about breaking the glass slipper, and how organizations historically (and continually) have crafted jobs and workplaces that encourage stereotypes. This was a bolder and more developed version of a talk she gave at NCWIT 2015.

Notes from Department Head Cal Ribbens

There is a lot of conversation on campus this spring about “Destination Areas,” a term that refers to ambitious new areas of growth in research and education at Virginia Tech.  You can learn much more about this discussion at the “Beyond Boundaries” site, which summarizes the bold challenge our new President and Provost has given us—to define what an internationally-recognized, global land-grant institution like Virginia Tech should look like in 2047.  The specifics of the Destination Areas are still emerging.  However, it is clear that computer science can and will play a pivotal role in all of them.  For example, a central Destination Area is in “Data and Decision Sciences.”  Our research and teaching emphasis in big data analytics allows us to play a leadership role in the definition of this destination area.   Other destination areas have working titles such as “Intelligent Infrastructure and Human-Centered Communities” and “Integrated Security,” so it is not difficult to make the case that CS is part of the discussion!

While we look forward to helping make Virginia Tech an even more attractive destination for new students and faculty, we also think about another kind of destination at this time of year, namely the next destination for our graduates.   It is always deeply gratifying to see the excitement of our soon-to-be alumni as they make plans for their next destination.  We will award over 200 BS degrees this year, along with over 30 M.S. and about 20 Ph.D. degrees.  For some, the next destination will be graduate school, military service, or a faculty position.  For others it will mean joining a spectacularly wide array of companies or agencies, from small start-ups in Blacksburg or Austin or San Francisco, to large contractors in Richmond or Charlotte or Arlington, to multinational companies in New York City or Seattle or Mountain View.  For all of our alumni, new and old, we are glad you decided to make CS@VT your destination for a few years, and we hope that decision has prepared you well for all your subsequent destinations!
