Ways of Seeing

Green Laser
ChenSeeing is for Humans, and Computers
Images are represented by pixels, which are just numbers with values. We analyze these numbers and detect what’s going on in a picture.
Tsuhan Chen, Electrical and Computer Engineering

KleinbergPeering into Social Networks
How does a person—or anything—become popular? How do groups arrive at consensus? How do opinions form? These are some of the questions at the interface of computer science and the social sciences that fascinate us.
A Conversation with Jon M. Kleinberg, Computer Science

Field and CuttingMovies, Pictures, and Visual Perception
Movies and pictures help us understand how the human visual system is organized.
A Conversation with David J. Field and James E. Cutting, Psychology

DavisTo Discover a Dream Material
We watch electrons—a billion times smaller than atoms—in complicated materials to enable the unimaginable materials of the future.
J. C. Séamus Davis, Physics

LipsonUsing Light in Unusual Ways
Little devices, including an all-optical switch, all-optical modulators, even cloaking devices—this is what the ability to manipulate light can yield. And Lipson has invented many little “light” devices for use in the microelectronics industry.
A Conversation with Michal Lipson, Electrical and Computer Engineering

MullerHow To Grow a Super Material or Troubleshoot a Classic One
Being able to see each atom of a material has allowed us to troubleshoot, discover, and create materials of all kinds.
David A. Muller, Applied and Engineering Physics

ParkLandscape: An Image or an Encounter with Nature?
As we go about living, in so many ways instead of looking and actually seeing, we’re just seeing the projections of things. We see not what we’re actually looking at, but what we think we want to see.
Maria Y. Park, Art

Van Clief-StefanonWhen a Poet Sees
Do you see yourself when looking into the mirror or how someone has described you? How much of what you see is being reflected back from society?
A Conversation with Lyrae van Clief-Stefanon, English

WangSingle Molecules Trapped for Study
To help us understand some of life’s mysteries, we have developed precision optical instruments and techniques to look at important molecules in biology—particularly DNA molecules and their associated proteins—one molecule at a time.
Michelle D. Wang, Physics

BlanchardWatching a Molecule Perform
The most effective disease treatments rely on getting tiny molecules inside the body to find and stop individual molecules from functioning.
A Conversation with Scott C. Blanchard, Physiology and Biophysics, Weill Cornell Medical College

ScherrThe Optical Biopsy
We want to create a better way to look inside the walls of a bladder for cancerous cells, eliminating the constant need for biopsies and saving the patient so much morbidity.
Douglas S. Scherr, Urology, Weill Cornell Medical College

SchafferOptical Tools for Seeing How Disease Changes The Brain
How do injuries to small blood vessels in the brain contribute to brain disease? Why don’t axons regrow after a spinal cord injury? What is the relationship between impaired brain blood flow and Alzheimer’s disease? To find out, we develop tools and techniques that let us see what is happening to individual cells inside the brain during disease development in animal models.
Chris B. Schaffer, Biomedical Engineering

ClarkFlies and Humans: Looking into Genetic Variation in Populations
How do differences in DNA sequences in a population produce variability in complex traits? We hope to learn basic principles of this correspondence in flies and apply those to understand variation in disease risk in people.
Andrew G. Clark, Molecular Biology and Genetics
