The University’s endowed assistant professorships recognize the achievements of promising junior faculty members. </p> <p>“I am honored to be named a Manning assistant professor. This endowed position will help support new research directions for me and my students,” said Hays.</p> <p>Hays’ research interests span computer graphics, computer vision, and computational photography. His research focuses on using "Internet-scale" data and crowd-sourcing to improve scene understanding and allow smarter image synthesis. Examples of recent research projects include: recognizing human sketched objects by learning from crowdsourced training data, restoring blurry photographs by modeling natural image statistics, and localizing photographs by predicting their overhead appearance and searching satellite imagery.</p> <p>Professor John Hughes stated, “James Hays has been doing really exciting work in both computational photography and at the boundary between computer graphics and computer vision, on areas as diverse as determine the age of color images, writing a program that can recognize human sketches (think "Pictionary"), and learning to determine image attributes like "indoors" or "manmade" or "socializing”. At the same time, James has developed courses in these areas that have energized students and led to multiple publications for them in top-rate venues. He's really the model of a Brown professor, balancing teaching, research, and service, and he's the ideal choice for the Manning Assistant Professorship.”</p> kpk@cs.brown.edu (kpk)Tue, 28 May 2013 10:11:14 -0400http://cs.brown.edu/news/2013/05/28/james-hays-named-manning-assistant-professor/Chad Jenkins Named National Geographic Emerging Explorer http://cs.brown.edu/news/2013/05/22/chad-jenkins-named-national-geographic-emerging-explorer/<div class="inset-image"><img alt="2004-0909.newfaculty.png" src="/media/filer_public_thumbnails/filer_public/2012/11/18/2004-0909newfaculty.png__149x200_q85_crop_upscale.jpg" width="149" height="200" /></div> <p><a href="http://www.nationalgeographic.com/explorers/bios/chad-jenkins/">Associate Professor Chad Jenkins has been named a 2013 National Geographic Emerging Explorer</a>.

Doug first began this project when he took Professor Istrail’s medical bioinformatics class in Fall 2012. He continued to work on it afterward and turned it into an honors thesis on the topic of maximum likelihood optimization. Beyond haplotype phasing, Doug was also interested in security and worked with Professor and Chair Roberto Tamassia on implementing and testing oblivious storage algorithms. He also worked on a self directed project to create a web portal providing easy access to lightweight encrypted storage.</p> <p>“Doug's independent research work culminating in his top department honor thesis, and his stellar performance in computer science and physics studies, are achievements that earned him this well-deserved recognition,” said Professor Istrail. “His thesis on maximum likelihood optimization, extending his final project in my graduate course Medical Bioinformatics defines an algebraic physics-inspired elasticity operator that explains what the quintessential, mysterious but practical EM algorithm is doing.”</p> kpk@cs.brown.edu (kpk)Thu, 16 May 2013 10:31:50 -0400http://cs.brown.edu/news/2013/05/16/yudi-fu-and-douglas-mcerlean-cra-outstanding-undergraduate-researchers-honorable-mentions/CS Faculty organized Second Human-Robot Interaction Symposium http://cs.brown.edu/news/2013/05/16/cs-faculty-organized-second-human-robot-interaction-symposium/<div class="inset-image"><img alt="robotics.jpeg" src="/media/filer_public_thumbnails/filer_public/2013/05/16/robotics.jpeg__250x250_q85_crop_upscale.jpg" width="250" height="250" /></div> <p>The Second Human-Robot Interaction Symposium, to further define and develop the HRI Initiative at Brown, was held at ICERM on May 6, 2013. The symposium was organized by Computer Science faculty Chad Jenkins and Michael Littman along with CLPS professor Bertram Malle, and was sponsored by the Department of Computer Science, the Office of the Provost, and the Office of the Vice President for Research.</p> <p>"Robotics is poised to be a game changing technology, which will change society over the next 40 years the way computing changed society in the last 40 years,” said Chad Jenkins. “Brown is in a unique position to guide robotics to improve both productivity and quality of life for people across society."</p> <p>The symposium’s goal was to introduce Brown faculty to one another’s work to help deepen as well as broaden the HRI Initiative. All participants were asked to write short paragraphs about how their current or future work might contribute to the HRI Initiative and introduce themselves to facilitate conversation. An intellectual marketplace was set up during lunch, a wall of white boards on which people brainstormed about how their research and ideas might form potential clusters under the initiative’s overarching themes.</p> <p>"It was amazing to me to see the breadth of research projects happening across the University and the exciting ways that they can be related to the central HRI vision," stated Michael Littman.</p> <p>Through interdisciplinary and collaborative effort, the HRI Initiative seeks to define: the societal needs robots can help fulfill; the technology and scientific knowledge to be gained in order to fulfill those needs; the human jobs needed to create and maintain the robots; the social, economic, and political impacts for humans interacting and working with robots; and training and preparation needed by students for this future.</p> <p>The symposium featured 18 presentations from faculty in the areas of Design and Materials, Robotic-aided Science and Exploration, Computation for Robotics, Social Cognition and Interaction, and Health and Medicine.</p> <p>"The symposium truly fulfilled its mission—to bring together a wide variety of scholars from all over campus whose work is relevant to HRI,” said Bertram Malle. “The more than 70 attendees covered 21 different units and departments at Brown.  In addition to an expected strong showing from CS, CLPS, and Engineering, we had representatives from Biomedical Engineering, Planetary Geosciences, Public Health, Orthopedics, Economics, Archeology, Music, Sociology, and the Watson Institute, and many more.  At Brown, great minds talk to one another."</p> kpk@cs.brown.edu (kpk)Thu, 16 May 2013 10:06:55 -0400http://cs.brown.edu/news/2013/05/16/cs-faculty-organized-second-human-robot-interaction-symposium/Jeff Huang Joins the Department as Assistant Professor http://cs.brown.edu/news/2013/05/14/jeff-huang-joins-department-assistant-professor/<p><div class="inset-image"><img alt="Jeff.Huang.jpeg" src="/media/filer_public_thumbnails/filer_public/2013/05/14/jeffhuang.jpeg__170x255_q85_crop_upscale.jpg" width="170" height="255" /></div> The Department is delighted to announce that Jeff Huang will be joining its faculty as assistant professor beginning August 1, 2013.</p> <p>Jeff’s research seeks to understand user interactions to drive new applications at the intersection of human-computer interaction and information retrieval.

Wallace McDowell Award for his contributions to multiprocessor computation. </p><p>Herlihy, whose research focuses on practical and theoretical aspects of concurrent and distributed computing, was recognized for his “fundamental contributions to the theory and practice of multi-processor computation.” His early work on wait-free synchronization showed that different synchronization operations have different computational power, but that any operation that can solve consensus is universal. </p><p>The McDowell Award is given to individuals for outstanding recent theoretical, design, educational, practical, or other innovative contributions in the field of computing. The award may be given for a single contribution of great merit or a series of lesser contributions that have had or are expected to have an important influence on the computer field. It consists of a bronze medal and a $2,000 honorarium. </p><p>Working with Jeannette Wing, Herlihy invented the notion of linearizability, a popular correctness condition for concurrent data structures. He developed counting networks, a class of highly-concurrent, low-contention data structures for counting and related tasks, with James Aspnes and Nir Shavit. Also with Shavit, he developed new ways to reason about distributed algorithms, based on combinatorial and algebraic topology, yielding new lower bounds to previously unsolved problems. With Eliot Moss, Herlihy co-invented transactional memory, a multiprocessor synchronization architecture that has been incorporated into recent processors by Intel and IBM. </p><p>Herlihy has an AB in Mathematics from Harvard University, and a PhD in Computer Science from Massachusetts Institute of Technology. He served on the faculty of Carnegie Mellon University and on the staff of DEC Cambridge Research Lab and was the recipient of the 2003 Dijkstra Prize in Distributed Computing, the 2004 Goedel Prize in Theoretical Computer Science, and the 2012 Dijkstra Prize in Distributed Computing.

The symposium was organized by Chad, Michael, and <span class="plugin_link"><a href="http://www.brown.edu/Departments/CLPS/people/bertram-malle">Bertram Malle</a></span> (CLPS) and was sponsored by the Department of Computer Science, the Digital Society Initiative, the Research Initiatives Office, and the Technology Ventures Office. The theme of the event was Fundamental Problems and Societal Solutions. </p><p>The symposium’s goal was to build a broad network of Brown scholars whose work speaks to issues of Human-Robot Interaction (HRI) and to draw attention to Brown’s existing capabilities and resources to advance innovative, high-impact research, teaching, and technology in this emerging field. It showcased current activities in five thematic areas: Perception, Decision, Interaction, Action, and Impact.</p> <p>The field of HRI raises fundamental questions about cognition and action in humans and robots and their increasingly sophisticated interactions. HRI research is inherently multidisciplinary and calls for contributions from science, the arts, and industry. HRI is also nationally recognized for its transformative impact on society. Applications of HRI to healthcare and medicine, service industries, manufacturing, and scientific exploration have the potential to enhance human productivity and enrich our quality of life. <br> <br> The symposium featured 20 informal ten-minute faculty presentations spanning diverse fields in the basic sciences, arts, humanities, and applied technology, setting the stage for rich HRI collaborations at Brown. </p> <p>“I think the symposium was a big success,” said Michael Littman. “It showcased some of the diverse and fascinating work going on all around campus.”<br> <br> </p><img class="ajT" src="https://mail.google.com/mail/u/2/images/cleardot.gif"> abt@cs.brown.edu (abt)Fri, 21 Dec 2012 10:20:27 -0500http://cs.brown.edu/news/2012/12/21/cs-faculty-co-host-human-robot-interaction-symposium/
