PROBLEMS IN BIOLOGICAL IMAGING: OPPORTUNITIES FOR SIGNAL PROCESSING

Jelena Kovacevic, Professor of Biomedical Engineering and Electrical and Computer Engineering, Director of the Center for Bioimage Informatics, Carnegie Mellon University

Abstract: The question I would like to help answer is: What is the role and what can imaging do for systems biology? In recent years, the focus in biological sciences has shifted from understanding single parts of larger systems, sort of vertical approach, to understanding complex systems at the cellular and molecular levels, horizontal approach. Thus the revolution of “omics” projects, genomics and now proteomics. Understanding complexity of biological systems is a task that requires acquisition, analysis and sharing of huge databases, and in particular, high-dimensional databases. Processing such huge amount of bioimages visually by biologists is inefficient, time-consuming and error-prone. Therefore, we would like to move towards automated, efficient and robust processing of such bioimage data sets. Moreover, some information hidden in the images may not be readily visually available. Thus, we do not only help humans by using sophisticated algorithms for faster and more efficient processing but also because new knowledge is generated through use of such algorithms.

The ultimate dream is to have distributed yet integrated large bioimage databases which would allow researchers to upload their data, have it processed, share the data, download data as well as platform-optimized code, etc, and all this in a common format. To achieve this goal, we must draw upon a whole host of sophisticated tools from signal processing, machine learning and scientific computing.

I will address some of these issues in this presentation, especially those where signal processing expertise can play a significant role.

COMPETITION AND COLLABORATION IN WIRELESS NETWORKS

Vincent Poor, University Professor of Electrical Engineering, Dean of the School of Engineering and Applied Sciences, Princeton University

Abstract: A major contemporary issue in the design and deployment of wireless networks is the dramatic increase in demand for new capacity and higher performance. The development of these capabilities is limited severely by the scarcity of the two principal resources in wireless networks, namely energy and bandwidth. Much of the capacity growth of the past two decades has been enabled by major advances in the wireless physical layer. However, in recent years, attention has turned increasingly to the higher network layers to examine interactions among nodes that can lead to even greater efficiencies in the use of wireless resources. This talk examines two types of such interactions: competition among nodes in multiple-access communication networks, and collaboration among nodes in wireless sensor networks. In the first context, the network is viewed as an economic system, in which terminals behave as agents competing for radio resources to optimize the energy efficiency with which they transmit messages. A game theoretic formalism is used to analyze the effects of various design choices and quality-of-service constraints on energy efficiency. In the second context, collaborative techniques for optimizing the use of radio resources in sensor networks are considered. Here, the focus is primarily on distributed inference, in which distinctive features of wireless sensor networks can be exploited through collaboration among nodes to affect a tradeoff between inferential accuracy and energy consumption.

Speaker biography: H. Vincent Poor is the Michael Henry Strater University Professor of Electrical Engineering and Dean of the School of Engineering and Applied Science at Princeton University. His primary research interests are in the area of wireless networks and related fields. Among his publications in these areas is the recent book, MIMO Wireless Communications (Cambridge University Press, 2007), coauthored with Ezio Biglieri, et al. Dr. Poor is a member of the U.S. National Academy of Engineering, a Fellow of the American Academy of Arts & Sciences, and a former Guggenheim Fellow. He is also a Fellow of the IEEE, the Institute of Mathematical Statistics, the Optical Society of America, a nd other scientific and technical organizations.

LESSONS LEARNED FORM THE INTERNET PROJECT

Douglas Comer, Vice President of Research Collaboration, Cisco Systems; Distinguished Professor of Computer Science, Purdue University

Abstract: The Internet ranks among the greatest achievements of 20th century computer science. The basic technology was so well conceived that it has remained virtually unchanged despite completely new applications and dramatic growth in the number of connected computers and traffic. This eclectic talk presents a series of lessons drawn from the Internet experience that may help us better understand how to proceed with new research. It considers the design of protocols, general principles, technologies, the underlying architecture, the effect of economics on networking research, and ways that experimental research projects can be organized to ensure success.

Speaker biography: Douglas Comer is VP of Research Collaboration at Cisco Systems and a Distinguished Professor of Computer Science at Purdue University, where he is currently on leave. Professor Comer is an internationally recognized expert on computer networking and the TCP/IP protocols. He has been working with TCP/IP and the Internet since the late 1970s. Comer established his reputation as a principal investigator on several early Internet research projects. He served as chairman of the CSNET technical committee, chairman of the DARPA Distributed Systems Architecture Board, and was a member of the Internet Activities Board (the group of researchers who built the Internet).

At Cisco Systems, Comer represents Cisco to the research community and to research universities. He works to establish research collaboration between engineers in Cisco and researchers in academia. He created and led the Technical Assessment Program, and founded and participating in the Cisco Research Board, and starting the Research and Innovation Exchange.

Comer has taught courses on TCP/IP and networking technologies for a variety of audiences, including graduate and undergraduate students, in-depth courses for engineers, and less technical courses for non-engineers.

SOFTWARE ENGINEERING RESEARCH AND THE INFLUENCE OF GROUP THINK

David Notkin, Bradley Chair and Professor of Computer Science and Engineering, University of Washington

Abstract: Software engineering is broadly discussed as falling far short of expectations. Data and examples are used to justify how software itself is often poor, how the engineering of software leaves much to be desired, and how research in software engineering has not made enough progress to help overcome these weaknesses. These data and examples, however, are presented and interpreted in ways that are arguably imbalanced. This imbalance, usually taken at face value, may be distracting the field from making significant progress towards improving the effective engineering of software, a goal the entire community shares. Research dichotomies, which tend to pit one approach against another, often subtly hint that there is a best way to engineer software or a best way to perform research on software. This, too, may be distracting the field from important classes of progress.

He has served as a member of the Computing Research Association board of directors since 2005, and co-chair of the Academic Alliance of the National Center for Women in Information Technology until 2008. In 1993, he was the program chair for the 1st ACM SIGSOFT Symposium on the Foundations of Software Engineering, and in 1995 was program co-chair for 17th International Conference on Software Engineering.
