Currently, my research interests are in Wireless Networks and Mobile Systems with emphasis on Security, Robustness and Survivability. Wireless and mobile networks are prone to certain threats that are either unique, or more pronounced for them. This is due to the constraints imposed by open air nature of the communication channel, bandwidth limitations and ever changing topology due to node mob...

If autonomous systems are to realize their potential, they must improve their abilities to operate in the real world. Sensorimotor systems are among the weakest and most critical components of such systems. Perceptual systems exist to enable their owners to cope with the dynamic environments in which they operate. The system is inundated by stimuli; the successful system selects the stimuli tha...

We model a situation involving N groups of players. Each player belongs to a single group, and enjoys a public good that is generated by members of that group. However, members of each group are also, to a greater or lesser extent, advantaged or disadvantaged by the public goods produced by other groups. We provide a simple but rigorous analysis of existence, uniqueness and comparative static p...

My main expertise is in numerical simulations of the Einstein equations in the fully non-linear regime. In particular, I am working on simulations of binary black hole systems. I have experience in both the time evolution of such systems and also in the construction of realistic initial data. Modeling the inspiral and merger phase of black hole binaries is one of the major challenges in gravita...

As the number of transistors that can be placed on a silicon chip continue to increase exponentially, as predicted by Moore’s Law, the design of electronic systems has moved away from the situation where discrete chips were assembled on a circuit board to one where entire systems or networks of systems are placed on a single chip. The design of these systems-on-chip (SoCs) and networks-onchip (...

Habermas’s theory of knowledge-constitutive interests (initially outlined in the Introduction) is intended to challenge what he regards as the ‘false objectivism’ of positivism’s conception of science and the relationship between theory and practice. This objectivism has two related elements. First, there is the belief that the objects of scientific knowledge exist independently of the epistemo...

I am a third year PhD student in Computer Science Department of Carnegie Mellon University. My advisor is Prof. Todd Mowry. My research interests are in database systems, computer architecture, operating systems, and distributed systems. I have worked on several research projects for my PhD study at Carnegie Mellon University and for my undergraduate and master theses at Tsinghua University, Ch...

s and posters at conferences, results presented at meetings (for example, to inform investigators or participants about findings), results databases (data without interpretation, discussion, context or conclusions in the form of tables and text to describe data/information where this is not easily presented in tabular form) are not considered by Blackwell Publishing to be prior publication. Jou...

My primary research interest is in statistical pattern recognition in general, and speech recognition in general; more specifically, I am especially interested in the emerging subfield of distant speech recognition (DSR), wherein it cannot be assumed that the microphone used for speech capture is directly adjacent to the speaker’s mouth; rather, the microphone might be located several meters aw...

Over the last few decades, computational science has extended the range of phenomena that can be investigated within the framework of physics. An important example are complex systems like spin glasses or neural networks, to name only two. Such systems are hampered by similar problems and can be studied with similar techniques. My work concentrates on a prominent example, the protein-folding pr...
