USA - 2007
For pioneering work in computational geometry, with profound applications across an astonishingly broad range of Computer Science disciplines.
Leonidas Guibas is a towering figure in theoretical computer science and a pioneer of computational geometry. His ground-breaking, fundamental research over the last quarter century has shaped the field of computational geometry since its infancy and helped it evolve and mature.
His passion for and dedication to establishing strong links with other disciplines has led him to make seminal contributions in computer graphics, computer vision, robotics, physical modeling, VLSI design, discrete algorithms, sensor networks, communication networks, and computational molecular biology. He is legendary for his remarkable rigor, coupled with a voracious appetite for new ideas, and the breadth of his contributions is an inspiration to colleagues and students alike.
Dr. Guibas has been called the Miles Davis of computational geometry, the ultimate Renaissance man of Computer Science, a modern-day version of Gottfried Leibniz. His record of fundamental contributions to so many different fields within Computer Science is astounding.
