Allen E. Puckett Professor of Electrical Engineering

Professor Perona's research focusses on vision: how do we see and how can we build machines that see.

Professor Perona has been mostly active in the area of visual recognition, more specifically visual categorization. He is studying how machines can learn to recognize frogs, cars, faces and trees with minimal human supervision, and how one could make large image collections and even the web searchable by image content.

In collaboration with Professors Anderson and Dickinson, professor Perona is building vision systems and statistical techniques for measuring actions and activities in fruit flies and mice. This enables geneticists and neuroethologists to investigate the relationship between genes, brains and behavior.

Professor Perona is also interested in studying how humans perform visual tasks, such as searching and recognizing image content. One of his recent projects studies how to harness the visual ability of thousands of people on the web for classifying and searching image content.

Theodore Y. Wu Professor of Environmental Science and Engineering; Jet Propulsion Laboratory Senior Research Scientist

Professor Schneider's research focuses on the climate dynamics of Earth and other planets. Its goal is to develop theories of climate and in particular of the atmospheric macroturbulence that largely controls it. Such theories help us understand the climate changes that occurred over Earth's history and that are likely to occur in the future. They also help us understand the circulations of other planets, for example, how jets on the giant planets form.

Shaler Arthur Hanisch Professor of Computer Science and Applied and Computational Mathematics

Professor Schröder is interested in the design of efficient and reliable algorithms for problems in computer graphics. These range from geometric modeling (effective methods to model the shape of objects) to animation (simulation of physical phenomena such as the deformation of cloth). His emphasis is on an area known as "Discrete Differential Geometry." Its goals are to rebuild the foundations of classical differential geometry in a discrete setting which makes it immediately useful for computation.

Professor of Applied Physics

Professor Schwab's current focus is on the question of quantum physics at large length scales, what does it take to observe quantum phenomena with ordinary matter and the largest possible scale. The techniques used to probe this are quantum-limited measurements of motion, ultra-low temperature physics, nanotechnology and microfabrication techniques, and ultra-sensitivity microwave measurement.

The Laboratory of Interfacial and Small Scale Transport {LIS2T} specializes in problems involving interface-mediated transport and "interface sculpting" in systems ranging in scale from microns to nanometers. Current topical areas include the study of free surface instabilities and self-assembling structures in liquefiable films triggered by thermal, electrical, Marangoni or magnetic field modulation; intrinsic 3D lithographic patterning of nanofilms; layering transitions and symmetry breaking in nanofilms; fluid interface modulation for micro-optic, photonic and field emission micropropulsion systems;  non-normality and unstable flows at low Reynolds number; biological flows governed by Marangoni forces; development of a universal slip condition for liquid on solid flows; and study of breakdown regimes in continuum flow vs molecular dynamics simulations. We complement full scale experimentation with analytic work, numerical computations and non-equilibrium molecular dynamics simulations to develop physical insight for theoretical advances as well as reliable design principles for application driven work.
