He was Deputy Director of the Fields Institute (1999–2003),
serving as Acting Director in 2000–01. His research interest
is mathematical logic and model theory in particular. He was
one of the organizers of the Algebraic Model Theory program
(1996–97).
Barbara Lee Keyfitz was Director of the Fields Institute
(2004–08). She is now the Dr. Charles Saltzer Professor of
Mathematics at the Ohio State University, and was previously
Moores Professor at the University of Houston. She studied at
the University of Toronto and the Courant Institute. She is a
Fellow of SIAM, of AAAS, of AMS and of the Fields Institute.
She has been President of the AWM and of the International
Council for Industrial and Applied Mathematics. Her research
area is nonlinear partial differential equations.
Peter Lancaster is Professor Emeritus at the University of
Calgary. While serving through the 1970s and 1980s in several
different capacities for the Canadian Mathematics Society, he
came to know the mathematical landscape in Canada. This
led to the invitation to serve on the Site Selection Committee
that was charged with finding a permanent home for the Fields
Institute. He was thus one of the passengers on the famous
bus.
William Langford obtained his BSc from Queen’s and his
PhD from Caltech. He taught at McGill University (1970–82)
and at the University of Guelph (1982–2004), where he is
now University Professor Emeritus. He was also a research
visitor at the Universities of Nice, Houston, Tianjin (China),
Warwick (U.K.), at IMA (Minnesota), and at INLN-CNRS
Sophia-Antipolis (France). He served as deputy Director of
the Fields Institute (1996–99).
John Mighton, a playwright and mathematician, believes
there are more connections between the arts and sciences than
people imagine, as both fields are often led by a sense of
beauty. He founded JUMP Math in 2001, fostering numeracy
