Research Topics

"Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost. Rigor should be a signal to the historian that the maps have been made, and the real explorers have gone elsewhere." -- W.S. Anglin

"The mathematician's patterns, like the painter's or the poet's, must be beautiful; the ideas, like the colors or the words, must fit together in a harmonious way. Beauty is the first test: there is no permanent place in the world for ugly mathematics."-- G.H. Hardy

"Perfection is reached, not when there is no longer anything to add, but when there is no longer anything to take away." --A. de Saint-Exupery
