Dennis Kafura receives XCaliber Award

Dennis Kafura, professor in the Department of Computer Science, has received the university’s 2016 XCaliber Award for an individual making extraordinary contributions to technology enriched active learning.

Established in 1996 by the Office of the Provost, the XCaliber Award is presented annually by Technology-enhanced Learning and Online Strategies to recognize individual faculty members or teams of faculty and staff who integrate technology in teaching and learning. The award celebrates innovative, student-centered approaches.

Kafura was a member of the university task force that defined learning objectives in the Pathways General Education area of Quantitative and Computational Thinking. As a result of these new objectives, he created and now teaches CS 1014, an Introduction to Computational Thinking course.

The course provides students with a perspective on the core ideas of computation and the methodology central to the practice of computing. Kafura’s teaching methodology centers around hands-on approaches and student engagement.

Students are actively engaged in setting the parameters of their data sets, posing the questions, and developing the program to answer their questions. To encourage collaboration, students are assigned cohorts of five to six students in which class participation and activities are completed.

CS 1014 is offered as an introductory course open to all majors. After just two offerings of the course in Fall 2014 and Spring 2015, student feedback showed student engagement was successful.

Kafura received his bachelor’s degree from the University of San Francisco and his master’s and doctorate degrees from Purdue University.

Ed Fox receives XCaliber Award

Edward A. Fox, professor in the Department of Computer Science, has received the university’s 2016 XCaliber Award for making extraordinary contributions to technology enriched active learning.

Established in 1996 by the Office of the Provost, the XCaliber Award is present annually by Technology-enhanced Learning and Online Strategies to recognize individual faculty members or teams of faculty and staff who integrate technology in teaching and learning. The award celebrates innovative, student-centered approaches.

Fox received the award in recognition for his work in developing and enhancing two new computer science courses, CS 4984, Computational Linguistics and CS 5604, Informational Retrieval.

The Computational Linguistics course gives students the opportunity to engage in active learning about how to work with large collections of text. Students engage in problem based learning with the challenge of analyzing content collections automatically, extracting key information, and generating easily readable summaries of important events.

The Information Retrieval course requires graduate students to analyze, index, store, search, retrieve, process, and present information and documents using fully automatic systems.

Both courses are focused on student engagement and mastery of the material. The objectives of the courses provide students with skills that are in great demand.

Fox led the campus to join the Cloudera Academic Partnership in 2015, providing the university with educational resources and support provided by this leading company in the area.

He received his bachelor’s degree from M.I.T. and his master’s degree and Ph.D. degrees from Cornell University.

Dennis Kafura’s Computational Thinking course part of the new Pathways to General Education curriculum

The implementation plan for Virginia Tech’s new general education curriculum, Pathways to General Education, was approved after a vote Monday at University Council. The implementation plan maps out how the new curriculum, which was approved in April 2015 to replace the current Curriculum for Liberal Education, will be phased in at the university.

Pathways to General Education will go into effect for new students entering in fall 2018. In the meantime, with the passage of the implementation plan, faculty will soon be able to propose courses, minors, and alternative pathways for approval. An official call for proposals will go out through Virginia Tech News. Reviews will begin in fall 2016, with some courses beginning as pilots in 2017.

Over the past couple of years, faculty have begun piloting courses that will meet the new Pathways to General Education requirements. Dennis Kafura, CS@VT professor, piloted a computational thinking course, which will expose students from a variety of disciplines to this way of solving problems. “Personally, I had little experience teaching a general education course – let alone developing one – and my career-long teaching was strongly oriented toward a traditional lecture model,” Kafura said. “However, the ‘computational thinking’ course came to include active learning, peer learning, problem-based learning, and a dash of flipping the classroom.”

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.
