Philip Klein Named ACM Fellow


The Association for Computing Machinery (ACM) recently elevated Philip Klein to Fellow for his work in graph and network algorithms.

Philip, who joined the department in 1989, focuses on algorithms, especially for optimization and for graphs. He is the recipient of the 2007 Philip J. Bray Award for Excellence in Teaching in the Sciences. He created six courses for the department: The Matrix in Computer Science, Computer Science: An Integrated Introduction I and II (with Leslie P. Kaelbling), Design and Analysis of Algorithms, Topics in Advanced Algorithms, Solving Hard Problems in Combinatorial Optimization: Theory and Systems (with Pascal Van Hentenryck ...

PhD Student Carleton Coffrin Finalist in INFORMS Student Competition


This image depicts the deployment of Carleton's work in Los Alamos National Laboratory's Logi-Sims tool. The image presents the effects of hurricane landfall on Florida's south-east shore. The shaded-concentric lines indicate the hurricane's wind speed,

Carleton Coffrin, a Ph.D. student working with Pascal Van Hentenryck, was chosen as one of six finalists in the INFORMS 2010 Doing Good with Good OR Student Paper Competition for his work on “Strategic Planning for Disaster Recovery with Stochastic Last Mile Distribution”, which was presented this year as a paper in the Conference on Integration of Artificial Intelligence and ...

Philip Klein, Claire Mathieu and Ph.D. Alum Glencora Borradaile Receive NSF Grant to Develop New Algorithms for Solving Optimization Problems on Planar Networks


The National Science Foundation (NSF) has awarded a research grant, in the expected amount of $800,000, to Philip Klein, Claire Mathieu and Ph.D. alum Glencora Borradaile (now Assistant Professor in the School of Electrical Engineering and Computer Science at Oregon State University), to develop new algorithms for solving fundamental optimization problems on planar networks. Many optimization problems in networks are considered computationally difficult; some are even difficult to solve approximately. However, problems often become easier when the input network is restricted to be planar, i.e., when it can be drawn on the plane so that no edges ...

BU, Brown and UC Irvine receive $3 million NSF grant

Computer scientists from Boston University, Brown University and the University of California, Irvine, will collaborate on a grant from the National Science Foundation (NSF) in the anticipated amount of $3 million to investigate "trustworthy interaction in the cloud." The cloud refers to Internet-based outsourced computation (popularly know as cloud computing), whereby shared resources, software, and information are provided to computers and other devices on demand.

As one of the most promising emerging concepts in information technology, outsourced computation is transforming how IT is consumed and managed, yielding improved cost efficiencies and delivering flexible, on-demand scalability. However, despite the ...

Ben Raphael and Eli Upfal Receive NSF Grant to Develop Techniques for Analysis of DNA Sequence Variants

The National Science Foundation (NSF) awarded a research grant, in the expected amount of $500,000, to Ben Raphael and Eli Upfal to develop robust algorithmic and statistical techniques for the analysis of DNA sequence variants in the context of known and novel gene-gene interactions. These techniques will allow biomedical researchers to identify DNA variants associated with risk for various diseases, including cancer. Algorithms developed in this project will be implemented and released as open-source software for use by the biological and medical community. The project will also support the training of graduate students and undergraduate researchers.

Sorin Istrail Awarded Title of Professor Honoris Causa from Alexandru Ioan Cuza University


As part of the celebration of its 150th anniversary, Alexandru Ioan Cuza University in Iasi, Romania, presented an honorary professorship (Professor Honoris Causa) to alumnus Sorin Istrail. “I am very humbled and honored to receive this recognition,” he said.

Sorin’s alma mater, where he earned a B.S. in computer science in 1975, also was celebrating the centennial of its Alexandru Myller Mathematical Seminar. Sorin helped commemorate the anniversary by participating in the seminar as an invited lecturer, delivering a technical talk titled “Concepts of Mathematical Rigor for Algorithms in De-randomization, Statistical Physics, and Molecular Biology.”

The lecture’s ...
