  • CSE Alumnus and New Faculty Member Picks Up Award in Scotland

    One of CSE's newest teaching professors, Leo Porter, has just received a best-paper award that recognizes his work as a researcher in the field of peer instruction. The Chair's Award at the annual ICER meeting recognizes the paper that best illustrates "the highest standards of empirical computing education research." At ICER 2014 in Glasgow, Scotland, the award honored Porter's paper on "predicting student success using fine grain clicker data."

    Porter (bottom, and far right) was on hand to receive the award from conference chair Quintin Cutts, on behalf of himself and his two co-authors from Canada (Daniel Zingaro from the University of Toronto Misssissauga) and Australia (Raymond Lister from the University of Technology, Sydney).

    Porter and his colleagues used data derived from the use of clickers in the classroom, and they reported that clicker data can help predict which students are likely to succeed, or fail, on the final exam in an introductory computer science class. "Our results identify performance during the first three weeks of the term as a significant predictor of their success," notes Porter, who joined the CSE faculty at UC San Diego as of July 1, from Skidmore College. "It also allows us to identify which individual questions were most meaningful." Specifically, the paper found that the predictive nature of the questions in the study applied to code-writing questions, multiple-choice questions, and the final exam as a whole.

    According to Porter, the award-winning paper marks a shift from papers about peer instruction as a successful pedagogy, to examining what researchers can do with the data which is naturally generated when a course is taught using peer instruction. He also thinks that the paper stood out in suggesting a new approach to identifying key student misconceptions and course concepts that have traditionally been built on qualitative interviews with students. "Our work suggests a data-driven approach using data which occurs during student in-class learning," explains Porter. "We can even identify individual questions and their associated concepts which, if answered incorrectly, make students likely to do poorly on the final."

  • Caught Between Theory, Practice and Peer Review

    The CRYPTO 2014 conference attracted nearly 400 experts to UC Santa Barbara recently, where one of the highlights was the Aug. 18 International Association for Cryptologic Research (IACR) Distinguished Lecture by CSE Prof. Mihir Bellare from UC San Diego.

    While he presented for an audience with specific interests in cryptology and cryptography, Bellare covered what he called (with characteristic understatement) "topics of quite broad interest" -- namely, being "caught between theory, practice, and peer review," the title of his talk (first slide pictured at right). The broad sweep of his remarks reflected Bellare's early interests in literature and history. Having come relatively late to science, Bellare told his audience, "In the company of theoreticians I feel liked a practitioner, while in the company of practitioners, I feel like a theoretician. It's not just me: our research community is caught between theory and practice."

    In the second part of his talk, Bellare focused on peer review, asking "how well does the process work?" and answering his own question bluntly: "Not very well." He went on to explore how "our culture incentivizes and perpetuates rejection." "Peer review is a broken, dark ages system," he added, "because it is fundamentally at odds with human nature and history." Bellare exhorted his colleagues to treat the peer review system as a research problem. "Think, write, talk, experiment," he said. "Our community is creative and imaginative. We have never shied away from hard problems. We have solved many. This is another." Bellare favors trying out new reviewing systems, and creating experimental publication venues. He also thinks academe could look elsewhere for ideas: discarding highest and lowest scores is used by the Olympics, so why not in the peer review process?

  • CSE Researchers Report Security Flaws in Backscatter X-ray Scanners

    A team of researchers from UC San Diego's Computer Science and Engineering department and co-authors from the University of Michigan, and Johns Hopkins University have discovered several security vulnerabilities in full-body backscatter X-ray scanners deployed to U.S. airports between 2009 and 2013.

    In laboratory tests, the team was able to successfully conceal firearms and plastic explosive simulants from the Rapiscan Secure 1000 scanner.  The team was also able to modify the scanner operating software so it presents an “all-clear” image to the operator even when contraband was detected.  “Frankly, we were shocked by what we found,” said J. Alex Halderman, a professor of computer science at the University of Michigan. “A clever attacker can smuggle contraband past the machines using surprisingly low-tech techniques.”

    The researchers attribute these shortcomings to the process by which the machines were designed and evaluated before their introduction at airports.  “The system’s designers seem to have assumed that attackers would not have access to a Secure 1000 to test and refine their attacks,” said Hovav Shacham (above right, with CSE Ph.D. student Keaton Mowery), a professor of computer science at UC San Diego.  However, the researchers were able to purchase a government-surplus machine found on eBay and subject it to laboratory testing.

    Many physical security systems that protect critical infrastructure are evaluated in secret, without input from the public or independent experts, the researchers said.  In the case of the Secure 1000, that secrecy did not produce a system that can resist attackers who study and adapt to new security measures.  “Secret testing should be replaced or augmented by rigorous, public, independent testing of the sort common in computer security,” said Shacham (at left, in front of the backscatter x-ray scanner as during a security check).

    Secure 1000 scanners were removed from airports in 2013 due to privacy concerns, and are now being repurposed to jails, courthouses, and other government facilities.  The researchers have suggested changes to screening procedures that can reduce, but not eliminate, the scanners’ blind spots.  However, “any screening process that uses these machines has to take into account their limitations,” said Shacham.

    The researchers shared their findings with the Department of Homeland Security and Rapiscan, the scanner’s manufacturer, in May.  The team will present their findings publicly at the USENIX Security conference, Thursday Aug. 21, in San Diego.  (Photos by Erik Jepsen/UC San Diego Publications)

  • Computer Science at UC San Diego Ranked #11 in World

    UC San Diego is doing great in the Academic Ranking of World Universities (ARWU) compiled annually by Shanghai Jia Tong University, and CSE is doing even better, based on the results for computer science programs.

    The 2014 rankings are out, pegging UC San Diego as the #14 university in the world. At the same time, the ARWU released its field-by-field rankings, and in the computer science category, CSE tied with USC for the #11 spot. That put computer science at UCSD just ahead of #13-ranked Caltech and the University of Illinois at Urbana-Champaign at #14. Both the campus and computer science rankings were unchanged from the 2013 level.

    CSE’s reputation, however, is substantially up from just a few years ago, based on the same ranking system. In 2011 computer science at UCSD was #16 in the world, then rose to #14, before jumping to #11 in 2013 and plateauing this year.

    UC San Diego appears to have benefited from the relative strength of its track record in computer science papers, citations and quality of publications, which together account for 75 percent of data on which the ARWU subject rankings are based. The relative weights in each category: 25 percent of the university’s score comes from highly-cited (HiCi) researchers in computer science; 25 percent on the number of papers in all computer science-related publications and conferences; and since 2009, ARWU also looks at the percentage of those papers published in the top fifth of computer science journals (a measure of the quality of papers). The final 25 percent of each university’s score is based on whether the program boasts any alumni or current faculty who have received the highest award in computer science, the Turing Award (none at UCSD).

    The ARWU rankings grew out of China’s need to benchmark how well Chinese universities perform against the best universities in other countries. Since the primary focus was on research, experts consider the ranking system the most useful in assessing “raw research power” (in the words of one UK expert). The ARWU has ranked the Top 500 universities since 2003.
