A $300,000 gift by Paul Maritz, Chief Executive Officer of Pivotal (an EMC-backed startup), is providing the critical resources needed to launch BU’s Cloud Computing Initiative (CCI), which is incubated at the Hariri Institute for Computing, and which is spearheaded by CS Research Professor and Institute Fellow, Orran Krieger.
Recently named as one of the 50 Most Powerful People in Enterprise Technology, Paul Maritz formed Pivotal in 2013. At its core, Pivotal builds big data infrastructures, which are able to handle next-generation workloads, and which can be adopted broadly through development and use of application-friendly platforms. Before being tapped by EMC Corporation to lead Pivotal, Maritz served as Chief Strategist of EMC, and as CEO of VMware Inc., where he remains a member of its board of directors. During his tenure at VMware, Maritz led the transformation of the company from a technology leader in virtualization to a category leader in cloud computing.
On July 10, 2013, The Council on Competitiveness, in conjunction with the U.S. House of Representatives Science and National Labs Caucus, held a briefing titled Extreme Computing: Why United States Industry, National Labs, and Academia Need Advanced Computing. More
BU has joined edX, the Harvard-and-MIT-led online learning platform that shares the University’s commitment to using technology’s benefits for students on campus as well as off. The partnership will give BU professors more flexibility in designing their courses and discerning which educational methods work best with students.
Membership obligates BU to offer five MOOCs (massive open online courses) via edX, says Jean Morrison, University provost. MOOCs typically enable people around the world to take a university class for free, sans credit. But BU and edX also espouse blended, or hybrid, courses: for-credit classes that mingle face-to-face instruction with online work, says Elizabeth Loizeaux, associate provost for undergraduate affairs and cochair of the University’s Council on Educational Technology and Learning Innovation (CETLI).
Dan O’Connell, edX spokesperson, says hybrid courses allow professors to shift time normally spent on lectures to one-on-one or small-group teaching, to field trips, or to additional lectures delving more deeply into topics. O’Connell says early results from a pilot project edX is running in California show decreased failure rates in a hybrid course, compared to the traditional classroom version.
“The hybrid model provides the best of both worlds,” says Loizeaux, a College of Arts & Sciences professor of English. “It promotes the face-to-face nature of…classroom interactions,” both students-to-teacher and between students. It simultaneously offers students “the flexibility to access content online at their own pace,” she says, while allowing faculty to use technology for “presenting information and assessing learning outcomes in ways that are not possible in a traditional classroom setting.”
BU President Robert A. Brown says he is delighted that the University is joining the edX consortium. “I am pleased to help pioneer the development of digital learning environments,” says Brown. “And I’m excited about the opportunity to use these enhanced learning tools for our residential students, and to invent new hybrid educational platforms as the next step in our ongoing significant commitment to online learning, especially for our students in graduate professional programs.”
EdX will also extend BU’s significant global reach, both by making BU professors and courses accessible to a global audience, and by increasing global connections for BU students. For example, study abroad might be enhanced by online minicourses before, during, and after the main course; online modules or courses could connect BU students with other students around the world; and online courses might even enable students whose schedules currently keep them at home to study abroad.
EdX’s ability to help professors evaluate how well students are learning course material was a big factor in BU’s choosing it over other platforms, Loizeaux says. The edX platform is designed to capture data on how students learn, she says, a capability that put it head and shoulders above other platforms BU considered, because it will aid professors in understanding which pedagogical approaches best advance student learning.
What kind of data? “We are talking about ‘big data’ from hundreds of thousands of learners,” O’Connell says. (According to edX, 700,000 students currently use its platform.) “EdX collects every click, and also, along with collaborating universities, conducts surveys throughout each course.”
The data dig deep into the digital weeds, he says. For example, says Azer Bestavros, CETLI cochair and a CAS professor of computer science, “Course evaluators can see how often a student rewinds to review parts of lectures—possibly indicating that clarifications are necessary—and also factors affecting students’ completion of courses. Such data goes beyond that available from courses offered by BU and taken by BU students.” Bestavros notes that for any hybrid courses the University develops on edX, “we will have full control regarding what we measure and how we analyze it, and…that data will not be shared with other institutions.” Only aggregated data from all edX members is shared, he says.
As a nonprofit in a field filled with for-profit competitors, edX “aligns with CETLI’s sense of values and what we believe to be BU’s best interest,” says Bestavros, who is also director of the Hariri Institute for Computing and Computational Science & Engineering.
The first hybrid courses on edX likely will be available “within the next couple of years,” Loizeaux says, while the MOOCs will be available in one year. EdX will complement, not replace, BU’s Blackboard e-learning system.
With more than 200 universities worldwide hoping for admission to edX—and with several elite institutions already in—“we are extraordinarily excited to be joining edX,” Morrison says. “It gives us the opportunity to collaborate with the consortium members on using their experience to better understand online learning.…We can learn from each other and develop best practices around higher education.”
Along with BU, edX welcomes several other institutions, including Cornell University, Davidson College, Berklee College of Music, Université catholique de Louvain (Belgium), Munich’s Technical University, the University of Washington, China’s Tsinghua University, Peking University, Japan’s Kyoto University, the University of Hong Kong, Hong Kong University of Science & Technology, Seoul National University, Karolinska Institutet (Sweden), and the University of Queensland (Australia).
They join the founders plus the University of California, Berkeley, Rice University, the University of Texas, Wellesley College, Georgetown University, École Polytechnique Fédérale de Lausanne (Switzerland), Australian National University, Delft University of Technology (the Netherlands), and Canada’s McGill University and the University of Toronto.
“EdX is thrilled to welcome Boston University,” O’Connell says. Calling the University “a world-class institution with top faculty and courses,” he says the partnership will benefit both: edX will help BU “incorporate sophisticated online course work into its on-campus curriculum,” while BU “will help us extend our range” of courses reflecting “the diversity of the people on our platform.”
President Robert A. Brown created CETLI to examine developments in online education and recommend a plan for extending BU’s current technology use to enhance instruction for tuition-paying residential students. It also is to recommend ways to reach new audiences off campus who wanted to sample the University’s offerings. As part of its work, CETLI sponsored a symposium and forums this spring to discuss the issues it was considering. Through the CETLI Seed Grant program, it will also make grants to faculty to develop innovative approaches over the next year.
The EdTech Ideas Fest, organized by the Council on Educational Technology and Learning Innovation (CETLI), was held at the Hariri Institute on April 22, 2013. The Fest featured presentations by 30 faculty members on envisioned novel uses of educational technology.
Approval to proceed with the plan for the new building to house the Institute (at 645 Commonwealth Avenue, site of the former Burger King) comes after 18 months of review. One of the first orders of business will be commissioning architects’ designs for the building which will also house the College of Arts & Sciences departments of computer science and of mathematics and statistics.
An undergraduate team from BU took first place in the International Genetically Engineered Machine (iGEM) Americas East competition, leading to a presentation at the World Championship last month across the river in Cambridge, MA. The iGEM Foundation focuses on advancing the field of synthetic biology. Team members Monique De Freitas (MET ’13) and Shawn Jin (SAR ’15) worked over the summer and into the fall on methods to track data about genetic circuits.
The Massachusetts Green High Performance Computing Center (MGHPCC) opened in Holyoke on November 16, with a ribbon-cutting ceremony and tour attended by Governor Deval Patrick, Lieutenant Governor Tim Murray, local politicians, and representatives of the five universities in the consortium, including BU. The facility has 10 megawatts of power available for computing, and will include systems from Boston University, Harvard, MIT, Northeastern, and the University of Massachusetts. In addition, some of the space is set aside for other research institutions and companies to help spur economic development enabled by computational power, including “big data” analytics.
More information about using the BU systems at the MGHPCC can be found on the IS&T blog.

About the Fellows
Professor Jason Bohland, Assistant Professor in the Departments of Health Sciences and Speech, Language, and Hearing Sciences in the College of Health & Rehabilitation Sciences, joined the BU faculty in 2009. His research focuses on understanding the circuits in the brain, using a variety of methods to gather large-scale data about signaling among neurons in both mouse and human brains. He also serves as the Director of the Quantitative Neuroscience Laboratory. Prof. Bohland received his Ph.D. at Boston University specializing in cognitive and neural systems.
Prof. Kathleen Morgan, chair of the Department of Health Sciences, notes, “Jason’s creative and innovative research approach that integrates large data sets describing the brain’s underlying architecture (such as brainwide gene expression profiles and connectivity atlases) with functional data (such as fMRI measured in humans) has an exceedingly high probability of leading to major breakthroughs in our understanding of the brain. The outcome of integrating these quantitative data with behaviorally relevant brain maps will not only provide new insights into the brain’s basic architecture but also inform possible approaches to treat a wide range of disorders.”
Professor Luis Carvalho joined BU’s Department of Mathematics and Statistics after receiving his Ph.D. from Brown University in 2008. He began his education in Civil Engineering, with a focus on transportation engineering. As he learned more about operations research, he became more interested in the theory, leading to his work in statistical applications. His work has found applications in diverse areas, including unsupervised land cover classification from satellite images, assessing interaction among genes in genome-wide association studies, and identifying communities in social networks. Prof. Carvalho specializes in Bayesian statistics, computational biology, and statistical inference.
Prof. Tasso Kaper, chair of the Department of Mathematics and Statistics says, “Our department is proud that Prof. Luis Carvalho has been named as a Junior Fellow of the Hariri Institute for Computing in recognition of his pioneering research in computational statistics and computational biology. He has developed new Bayesian statistical methods for analyzing high-dimensional data arising in sequence analysis, RNA secondary structure prediction and classification, and phylogenetic analysis. In addition, he has begun to address the problem of extending genome-wide association analysis methods to detect gene-gene interactions, among new collaborations with colleagues in the Bioinformatics Program. Outside of biology, Luis has made contributions to statistical aspects of land-cover classification data with colleagues in Earth Sciences at Boston University and to transportation engineering.”
Professor Dino Christenson, Assistant Professor in the Department of Political Science, received his Ph.D. from Ohio State University in 2010, and came to the BU faculty later that year. He studies American political behavior with a focus on the context in which individuals and organizations seek out, receive and process political information. His recent work concerns campaign dynamics in the early stages of presidential primary elections and interest group networks. Prof. Christenson also serves as the Director of the Honors and BA/MA programs for his department and is the co-Organizer of the Research in American and Comparative Politics Workshop.
Prof. Graham Wilson, chair of the Department of Political Science, notes that “Dino is a dynamic engaging teacher and scholar who has already made a big impact on our department. He brings skills and perspectives to the department that we have long needed. We are so fortunate to have him.”
Professor Douglas Densmore was awarded his Ph.D. from the University of California, Berkeley in 2007. Originally interested in programming video games, Prof. Densmore discovered an interest in microprocessor design, leading to his expertise in computer-aided design (CAD) tools. A postdoctoral fellowship enabled him to start applying this expertise to the design of CAD tools for synthetic biology, opening up an exciting new area in life sciences. In addition to working in the Department of Electrical and Computer Engineering, Densmore also serves as Affiliated Investigator for the Synthetic Biology Engineering Research Center.
Regarding Densmore’s work, Prof. David Castañón, chair of the Department of Electrical and Computer Engineering, says, “Prof. Densmore’s research merges ideas from electronic design automation with synthetic biology. Specifically, he examines how to create design automation tools that allow for the high level specification, design, and assembly of new biological systems. His work will increase the complexity of feasible designs, reduce design time, and allow for truly engineered biological systems. His efforts have attracted significant funding from various agencies, as well as prestigious awards such as the Richard and and Minda Reidy Professorship and Gold Medals from the International Genetically Engineered Machine (iGEM) Competition. His interactions with the Hariri Institute will aid the development of computational sciences to enable the design of complex biological organisms with the rigor and precision that is associated with modern design of integrated electronics.”
Professor Sharon Goldberg joined BU’s Department of Computer Science in 2010. Her research focuses on the security and privacy of computer networks, by combining formal techniques from cryptography and game theory with empirical network data and large-scale simulations. She has served on working groups of the advisory council to the Federal Communications Commission (FCC) on the security and reliability of telecommunications systems. Prof. Goldberg received her Ph.D. from Princeton University in July of 2009. Before coming to BU, she worked as a postdoctoral researcher at Microsoft Research, New England.
Prof. Stan Sclaroff, chair of the Department of Computer Science, says, “Sharon is a rising star in the critical area of Internet security. Her interdisciplinary work leverages ideas from economic game theory to devise incentives that will make the Internet infrastructure more secure. Her work gets noticed by network operators, Internet standards bodies, and even the Federal Communications Commission, which has convened a working group in response to Sharon’s groundbreaking research findings. We are delighted that Sharon has been selected as a Hariri Institute Junior Faculty Fellow.”
Professor Nachiketa Sahoo joined the Information Systems Department in the School of Management in July of 2011. His research includes applying machine learning techniques to problems in social science. For example, how should recommendation systems (such as for books or movies) handle changing preferences among the customers? In another arena, how can publications, blog posts, and comments be used to identify individuals with particular areas of expertise? Before working at Boston University, Prof. Sahoo earned his Ph.D. from Carnegie Mellon University’s Heinz College.
Prof. Chris Dellarocas, chair of Information Systems, notes, “Nachi does cross disciplinary research on managing information overload. He has brought together ideas from social science and methods from statistical machine learning to design novel personalized information filtering techniques. I see a lot of potential for him as he expands his research into the phenomena of social/human information filtering over online social networks. His exposure to the Hariri Institute has already led to a collaboration with members of BU’s Computer Science department so I am thrilled to see him recognized as a Hariri Institute Junior Faculty Fellow.”
