  • Society Honors Computer Scientist and Mathematician Fan Chung Graham

    CSE Prof. Fan Chung Graham and 30 others worldwide have been named as the Class of 2015 Fellows of the Society for Industrial and Applied Mathematics (SIAM). She was cited for her contributions to “combinatorics, graph theory and their applications,” and those applications have included Internet computing, communication networks, software reliability and more.

    The Distinguished Professor has joint appointments in CSE and the Department of Mathematics, where she holds the Paul Erdös Chair in Combinatorics. In the early 1990s, Chung Graham served on the council of SIAM.

    She is not the only Graham to be honored by SIAM – not even in the Graham household. That’s because her husband and fellow CSE professor, Ronald Graham, was honored in 2009 to be included in the inaugural class of SIAM Fellows. Ron Graham is also Chief Scientist in the California Institute for Telecommunications and Information Technology (Calit2).

    In 2013, Chung Graham and her husband were recruited to the inaugural class of Fellows of the American Mathematical Society. Both are experts in theoretical computer science and combinatorics.  Among her other honors, Chung Graham received the Allendoerfer Award from the Mathematical Association of America in 1990, and she is one of three CSE professors awarded membership in the American Academy of Arts and Sciences. (The others? Larry Smarr and... Ron Graham).

    Chung Graham earned her Ph.D. in mathematics from the University of Pennsylvania in 1974. She went on to work at Bell Labs in its Mathematical Foundations of Computing department.

  • Cyber Privacy App Gets Boost from CSE Alumnus, Research Scientist Now Teaching at Carnegie Mellon

    CSE got a plug from one of its alumni and former research scientist in an article about how most apps don't care about privacy. CSE alumnus Yuvraj Agarwal (Ph.D. '09) left UC San Diego in 2013 to be an assistant professor of computer science at Carnegie Mellon University, where he founded that university's Systems Networking and Energy Efficiency Lab. But when interviewed by the Pittsburgh Post-Gazette for a piece on privacy and apps, Agarwal noted that his team at UCSD had developed an app called Protect My Privacy in 2012, at a time when Apple had not yet offered its AppOpps rival. "Protect My Privacy sends user notifications when an app attempts to access location data, contacts or other information with the phone,"  noted Agarwal (pictured at UCSD demonstrating the app). Protect My Privacy, however, goes beyond what AppOpps can do, by intercepting communication between the app and the phone before any information is lost.

    On the downside, Protect My Privacy can only work on iPhones that have been modified to allow customization, or that have been 'jailbroken.'  Even so, Agarwal confirmed that an iOS 8 version of Protect My Privacy was released in late March, and since its launch, the app has been downloaded more than 200,000 times. However, as people load more and more apps on their smartphones, they can generated potentially hundreds of alerts per day that may require the user to say yes or no to a request for information. Agarwal is quoted admitting that, "it can get overwhelming pretty quickly."

  • New Opportunities for CSE Students, Faculty in Qualcomm Institute Innovation Space

    The Qualcomm Institute is setting up a new space where companies can apply to lease offices or labs on the second floor of Atkinson Hall, across from the CSE building. The institute announced the first seven companies that have been approved to be the first tenants of the facility, with more in the queue. The space is not an incubator, but it's a natural home for faculty, staff or student startups, because it allows a founder to locate startup staff within easy walking distance from the faculty member's departmental office. The Qualcomm Institute Innovation Space (QIIS) was also designed to work closely with other campus units that make up the entrepreneurial ecosystem of UC San Diego, including venture capital funds (Triton Fund, UC Ventures), the Moxie Center for Student Entrepreneurship, The von Liebig Entrepreneurism Center, The Basement (the recently-launched incubator/accelerator program for student entrepreneurs), etc. 

    In addition to three faculty startups (Sinopia Biosciences, STEAM Engine and VirBELA) and three early-stage companies that collaborate closely with researchers on campus (Comhear, Technosylva and RAM Photonics), QIIS is now home to the Foundation for Learning Equality (FLE), launched by a team of undergraduate and graduate students including recent cognitive science alumnus Jamie Alexandre (pictured center back row). “It’s estimated that one in three children worldwide lacks access to a quality basic education,” said Alexandre. “Sixty percent of the global population lacks the connectivity needed to access online education, so we have been developing an offline version of Khan Academy. Since being launched in December of 2012, the open-source platform, KA Lite, has now been installed in more than 140 countries and is used by thousands of schools, orphanages, community centers, refugee camps and prisons.” The offline server can be downloaded and run on a basic device such as a Raspberry Pi or even on aging Windows PCs, then other devices nearby can connect to that server to access the Khan Academy videos. A teacher with a single server can provide a classroom of 35 students with simultaneous access to KA Lite, and track their progress using teacher dashboard tools to enable them to most effectively intervene and help students who are struggling. By being located in Atkinson Hall, FLE gets proximity to the population of student programmers it needs in order to keep rolling out enhancements of KA Lite, and CSE students are already actively engaged. Current interns and student workers from CSE include undergraduates Teresa Do, Christine Pham (all class of '15), as well as Chris Li and Antriksh Yadav (both class of '16). Also working on KA Lite, CSE grad student Srishty Agrawal (MS '16), and cognitive science major David Canas, who is minoring in computer science.

  • Bioinformatics Experiment Holds Promise for Industrial Production of Algae Biofuels

    CSE Prof. Vineet Bafna was on the roster of experts who spoke at the Green Revolution 2.0 symposium March 12-13 in the Qualcomm Institute, organized by the California Center for Algal Biology and the Center for Food and Fuel for the 21st Century. The bioinformatics expert addressed the “Ecology of Open Algae Ponds for the Production of Biofuels,” noting that algae are great feedstocks for biofuels and other products, but the challenge is to get yield at low cost. (In principle, microalgae may produce between 10 and 100 times more oil per acre than traditional crops, but that has not been achieved in an industrial setting.) “There is a general understanding in ecology that diversity is good for productivity, and that precept might be useful for industrial production,” explains Bafna. “But we don’t know that these ecological ideas can work in an industrial setting.”

    To test his hypothesis, Bafna’s team did a year-long experiment in which they monitored the prokaryotic and eukaryotic composition of an algae pond (pictured), using genome sequencing to assess the taxonomic composition and diversity in the pond. In addition to genomic sampling, they used phenotyping to gauge various measures of pond health. “We managed to optimize productivity of biomass over the course of a year,” says Bafna. “Our results strongly suggest that diversity is important for pond productivity, and even in a managed setting, open ponds behave like natural ecosystems.” The team’s results, as Bafna explained to the FF21 annual conference, indicate that algal diversity promotes production, and that understanding the ecology of open algae ponds for the production of biofuels is critical to managing their output of biomass energy and other products. The study was funded by NSF and carried out in a partnership with FF21 director Stephen Mayfield and Biological Sciences professor Jonathan Shurin (both from UC San Diego). Bafna also thanked collaborators at Sapphire Energy, Life Technologies and SDSU.

  • Center for Visual Computing Gets Ready to Take a Bow

    The Computer Science and Engineering department is home to a new research center on computer vision and graphics, computational imaging and augmented reality, to be announced soon. According to a report in the San Diego Union-Tribune, Sony is the largest founding sponsor of the new UC San Diego Center for Visual Computing. Together with Qualcomm, Pixar and Adobe, the companies are investing in a center that “will study everything from virtual and augmented reality to object recognition.”

    While a formal announcement is pending the launch of the center’s new website, founding director Ravi Ramamoorthi (pictured) is quoted as saying, “It is exciting to get this level of industry support in such a short timeframe, which indicates the high level of industry involvement with visual computing technologies, and the potential for major societal impact.”

    In the same March 13 newspaper article, Ramamoorthi is optimistic that other companies will flock to the center. “We expect to see even more sponsors join the center in the next few months,” he said, “and expect to further grow the visual computing effort and research group within the Jacobs School of Engineering.”

    The Center for Visual Computing is the third so-called “agile” research center announced in the past six months within the Jacobs School, and the first to be based in the CSE department. In addition to Ramamoorthi, founding faculty include CSE professors Henrik Wann Jensen, David Kriegman, Zhuowen Tu (joint Cognitive Science and CSE) and Qualcomm Institute research scientist Jurgen Schulze (CSE adjunct).

    According to Ramamoorthi, the center has settled on three overarching research themes: mobile visual computing and digital imaging; interactive digital (augmented) reality; and understanding people and their surroundings. For the latter, researchers aim to automate computer understanding of the visual world, from small-scale underwater organisms to large metropolitan environments.

    According to Ramamoorthi, the center aims to make a formal announcement before the school’s 2015 Research Expo on April 16. That’s when he is slated to represent the center among the faculty speakers, all of whom are based in the agile centers. His topic: the grand challenges in visual computing.

  • CSE Faculty, Students Among Winners for Frontiers of Innovation Scholars Program

    Five CSE graduate students have received inaugural Frontiers of Innovation Scholars Program (FISP) grants from the university. They include Jagannathan Venkatesh, a Ph.D. student working with CSE Prof. Tajana Rosing, and an as-yet-unnamed CSE graduate student who will work with Qualcomm Institute research scientist (and CSE instructor) Jurgen Schulze. For most of the grad students, the awards come with $25,000 scholarships. [Pictured l-r: Ph.D. students Venkatesh, Gautier, Shearer, and M.S. student Thangarajan, bottom right].
    Ph.D. student Quentin Gautier will work with CSE Prof. Ryan Kastner on 3D modeling for underwater archaeology, specifically to develop an underwater imaging platform for creating 3D models of underwater artifacts. Separately, Kastner will work with Qualcomm Institute manager Curt Schurgers as co-mentors for CSE Ph.D. student Alexandria Shearer, who will do her research on aerial LIDAR scanning. Shearer’s research is applied specifically to aerial laser scanning of Mayan archaeological sites (which are often complicated because ruins are inaccessible and tend to be located in areas with dense jungle canopies). “Both of these projects were kickstarted with previous awards from the Qualcomm Institute through its Calit2 Strategic Research Opportunities grant program,” noted Kastner.
    CSE research scientist Nadir Weibel was awarded $25,000, which will allow him to employ CSE Master’s student Narendran Thangarajan to work for the Winter and Spring quarters, after which he will graduate. The funding will allow Thangarajan to work on a project to detect the social networks of San Diegans considered at-risk of contracting HIV. “Through this interdisciplinary project, I am learning how to participate in research where human subjects are involved, as well as medical practices related to HIV,” said Thangarajan. “The Frontiers of Innovation funding will allow me to spend more time on research, which in turn will help our research project to advance and reach our envisioned goal.”
    According to CSE’s Weibel, the researchers will use "publicly available Twitter data to uncover the structure and content of the online social networks of HIV at-risk individuals." Once the Twitter network is characterized, it will be compared to the real-world network of patients already known to the UC San Diego School of Medicine's AntiViral Research Center (AVRC) and Dr. Susan Little, whose Primary Infection Research Consortium (PIRC) collects multidimensional epidemiological, clinical, treatment, social and behavioral data from HIV-infected and HIV at-risk individuals (hence the interdisciplinary nature of the research). "Our goal is to use the information from the online social network to initiate and inform targeted, real-world HIV prevention interventions," said Thangarajan. "This could involve stepped-up efforts in specific parts of the city, or specific segments of the population." 
    An additional group of graduate recipients from other departments will work under the co-mentorship of CSE faculty members including Kastner as well as Lawrence Saul, Gary Cottrell, and Vineet Bafna. 
    But that's not all. Among 100 students campus-wide to receive the smaller $3,000 scholarships for undergraduates, at least three are going to CSE students, and possibly double that number (because some of the grants were given to faculty for them to assign at their discretion). The named undergrads from CSE include senior Antonella Wilby (majoring in computer science) and Jorge Pacheco (computer engineering junior), who are part of a four-person team under professor Kastner in his capacity as co-director of the Engineers for Exploration program. Also getting funding: CSE undergrad Jennifer Lu, who will work with ECE Prof. Gert Lanckriet on a "multimodal machine learning framework for activity and mood recognition using mobile and stationary sensors."

  • Computer Engineering #13 in Graduate School Ranking

    U.S. News & World Report is out with its graduate school rankings for 2016. Although the Jacobs School of Engineering overall ranked #17 out of 195 engineering schools, there was better news in the part of the survey focused on computer engineering (which is split between CSE and Electrical and Computer Engineering). The UC San Diego computer engineering program tied for #13 with UCLA and the University of Southern California.

    There was nothing new to report on the computer science side. That's because the magazine does not do annual surveys of computer science programs, since at most schools computer science is not located inside of the engineering school. The last survey of computer science -- published in 2014 -- had UC San Diego tied for #15 among the top U.S. programs.

    Building on fundamental engineering strengths including wireless communications and biomedica engineering, the school is now developing new research centers in emerging, interdisciplinary research areas including wearable sensors, extreme events engineering, sustainable power and energy, and visual computing. The Best Graduate Schools rankings are based on two types of data: expert opinions about program excellence, and statistical indicators that measure the quality of a school's faculty, research and students.

  • CSE Alumna Receives NSF Funding for Internet Topology Project

    CSE Faculty-Affiliate and alumna Kimberly Claffy (MS ‘91, PhD ‘94) is a PI on a new $1.2 million NSF grant to measure and quantify the changing nature of the Internet’s topology and what it means for the Internet’s future in terms of design, operations, scientific study and public policy. “From both the scientific and policy perspectives, much of the Internet’s evolving ecosystem is largely uncharted territory,” said Claffy, director of the Center for Applied Internet Data Analysis (CAIDA) at the San Diego Supercomputer Center (SDSC). ““As the Internet expands to satisfy the demands and expectations of an ever-increasing percentage of the world's population, profound changes are occurring at myriad levels: from interconnection structure and traffic dynamics to creating new economic and political issues that need to be addressed.  These changes also pose broader challenges for technology investment and future network design, so a key goal of this project is to establish a baseline against which to evaluate future Internet architecture designs and implementations.” The project, joint with MIT’s Computer Science and Artificial Intelligence Laboratory,  is called e”NeTS: Large: Collaborative Research: Mapping Interconnection in the Internet: Colocation, Connectivity and Congestion.”

  • ‘Moving onto Deeper, More Interesting and More Challenging Problems’

    Industry, Academic Experts Flock to Annual Non-Volatile Memories Workshop

    Approximately 220 researchers from academic, industry and national labs were at UC San Diego in early March for the sixth annual Non-Volatile Memories Workshop. The annual event is co-organized by CSE’s Non-Volatile Systems Laboratory, Calit2’s Qualcomm Institute, and the Center for Magnetic Recording Research (CMRR). It took place in the Price Center March 1-3, culminating in a banquet at Mister A’s overlooking a dramatic downtown skyline. [Click here to view photos from the workshop and banquet]

    The workshop brought together scientists and engineers working on advanced, non-volatile storage devices and systems. “We expanded the program this year to reflect the strong set of submitted papers we received,” said CSE Prof. Steven Swanson (at right, with student), who co-founded the annual workshop and co-organized the 2015 event with ECE Prof. (and former CMRR director) Paul Siegel and Technion’s Eitan Yaakobi. “It’s been very exciting to see the community expand to tackle the wide range of challenges that non-volatile memories present. You can really see the evolution in the problems people are addressing.

    “As a community we have tackled many of the ‘low-hanging fruit’ and we are moving onto deeper, more interesting and more challenging problems,” he added.

    According to Swanson, high points of the 2015 NVM Workshop included industry participation in the form of keynote presentations by top people from Samsung, Intel and Seagate.

    Samsung senior vice-president Bob Brennan (at left), who leads the company’s Memory Solution Lab, addressed the conference on “How NAND-based Technology is Transforming the Data Center.”

    The March 2 afternoon speaker was Phil Brace, Executive VP of Electronic Solutions at Seagate Technology. His topic: “Storage – Moving Towards Tailored Solutions.”

    Then Intel’s Andy Rudoff opened the final day of the workshop, with the Principal Engineer musing on the subject, “In a World with Persistent Memory…”

    In addition to the industry keynotes and a half-day tutorial March 1 on the RAMCloud Storage System, the two parallel conference tracks packed more than 40 paper presentations by researchers from around the world – a substantial number of them working in industry, including at HP Labs, Sandisk, HGST San Jose Research Center, IBM Research in Zurich, Intel and Samsung.
