The economic aspects and physical realities of nanoscale IC design and manufacturing are creating more opportunities for programmable and reconfigurable circuits, but the performance advantages of application-specific circuit customization motivate the need for new design methodologies. Dr. Pileggi's research group is exploring various forms of circuit regularity and supporting design methodologies that will facilitate affordable nanoscale silicon IC implementation. This includes the creation of new regular fabrics for digital and analog circuit design that offer a continuum of trade-off opportunities from fully customizable to fully programmable circuits.
W.W.Mullins Professor and Dept Head - Materials Science and Engineering
The properties of surfaces and grain boundaries are influenced by their geometric and crystallographic structure, their stoichiometry, and their defect structure. Professor Rohrer’s research is aimed at the quantitative study of interfacial properties with the goal of defining structure-property relationships for interfaces. Current research in the area of polycrystalline structure has the goals of quantifying the population of different grain boundary types, measuring their properties, understanding the mechanism by which the network forms during processing, and understanding the influence that the network structure has on the macroscopic properties of the material. Current research in the area of metal oxide surfaces has the long range goal of developing composite polar oxide materials that make the photolytic production of hydrogen economically feasible.

Most of my research is interdisciplinary and is concerned with theoretical problems in materials science that lead to challenging problems in physics and mathematics. Examples are the thermodynamics of stressed solids, transport phenomena, surfaces and interfaces, phase transformations, the precise definition of chemical potentials in stressed solids, the fundamental basis of the Onsager reciprocal relations in multi-component diffusion and heat flow, and the influence of anisotropic surface tension on crystal shape.

In collaboration with scientists at Sector 1 of the Advanced Photon Source, we are developing a high energy x-ray diffraction microscope (XDM) and the software necessary to reconstruct three dimensional maps of microstructure. This technique probes grain geometries and orientations deep inside of bulk materials. Being non-destructive, the technique makes it possible to watch the dynamical behavior of microstructure well away from the influence of surfaces. A wide variety of materials applications can be imagined, including fundamental studies of grain growth and the response of ensembles of grains to the application of stress. This project is part of CMU's NSF sponsored Materials Research Science and Engineering Center.

My current research interests are mainly in the area of multiscale problems where bridging across scales of representation is a major focus. For example, how do the Navier-Stokes equations, or the Elasticity/Plasticity equations emerge from atomistic/molecular levels? What are the correct variables to introduce in modeling the problem on different scales? What are the predictable features of large systems of interacting entities (atoms/molecules, cells, etc.)? We deal with microscopic models which may be deterministic or stochastic, discrete or continuous and coarse graining of these models through intermediate scales to the macroscopic level is sought.
University Professor - Mathematical Sciences
My research concerns the development of mathematical tools for studying the oscillating solutions of the nonlinear partial differential equations of continuum mechanics. For physical phenomena described at a microscopic level you need to understand what equations should be used at a macroscopic level, and the mathematical model used is based on different notions of weak convergence.
