With inspiration coming from computational biology, computer science, and theoretical physics, much of the work revolves around discrete structures and their underlying topology and geometry. The fascination is not in the study of one object, but the space of all ways an object can deform and evolve.
Underneath this framework lies a strong desire for the proper visualization of data, from drawings to graphics to photography. Conveying results with visual clarity, accuracy, and simplicity is as important as the discovery of the ideas themselves.
These ideas should also be made incarnate, for the physical matters. Humans care about how things look, taste, feel, and sound. And mathematics is part of this tapestry, dealing not just with the mind, but the body as well, extending to our tangible world.
Some works and thoughts have appeared in venues such as NPR, The Times of London, and Forbes, with generous support over the years by the National Science Foundation, DARPA, the Mellon Foundation, the Whiting Fellowship, and the Templeton Foundation.
