**Stanley Burris**, University of Waterloo

Joined the Pure Math. Dept. at the University of Waterloo in 1968, and has published over 70 research papers since then. Research Associate to Alfred Tarski in 1971. Did research in Universal Algebra for over two decades, with a primary interest in Boolean constructions and decidability, leading to the 1981 Memoir “Decidability and Boolean Constructions” with Ralph McKenzie, and the popular textbook “A Course in Universal Algebra” with H.P. Sankappanavar. With increasing interests in computer science, in 1996 published “Logic for Mathematics and Computer Science”. In the 1990s started work on asymptotics and logic, leading to the 2001 book “Number Theoretic Density and Logical Limit Laws”. Has studied the history of logic, especially in the 19th century, for over two decades, leading to clarifying several aspects of Boole’s algebra of logic and the article “George Boole” in the online Stanford Encyclopedia of Philosophy. Being an avid fan of Photoshop, and of recognition of women in mathematics, spearheaded the MAA Women of Mathematics poster project, strongly supported by the MAA President at the time (2007-2008), Joseph Gallian.

**Amirouche Moktefi**, Tallinn University of Technology

Dr. Amirouche Moktefi is a research fellow at the Chair of Philosophy, Tallinn University of Technology (Estonia) and an invited lecturer at the Estonian Business School. He holds a PhD in History and Philosophy of Science at the University of Strasbourg, France, 2007. He has been teaching mathematics, logic, philosophy, philosophy of science and communication in several universities and schools. His research interests include the history of symbolic logic, the philosophy of mathematical practices, diagrammatic logic and the theory of logical opposition.

**Don Monk**, University of Colorado, Boulder

PhD 1961 at Univ. Calif. Berkeley under Alfred Tarski. Asst. Prof. - Assoc. Prof. - Prof. at University of Colorado, Boulder, 1962 -2015. Retired June 2015. Visitor at Eidgenossische Technische Hochschule, Zurich many times; also at Freie Universitat Berlin, Chechoslovak Academy of Sciences, Humboldt Universitat Berlin, Univ. of Calif., Berkeley, Ben Gurion University, Hungarian Academy of Sciences. Author of 9 books, co-editor of 4. 85 publications.

**Vaughan Pratt**, Stanford University

Vaughan Pratt is Professor Emeritus of Computer Science at Stanford University. He obtained his Ph.D. from Stanford under Donald Knuth. He taught at MIT from 1972 to 1981 and thereafter at Stanford. He is a Fellow of the Association for Computing Machinery. He has published over a hundred papers, over half of which are on logic, including dynamic logic as a marriage of modal logic and regular expressions and logics of concurrent behaviour based on Chu spaces. In other areas he is known for the Pratt parser, Pratt certificates, the Knuth-Morris-Pratt algorithm, and the Sun logo. In his retirement he wrote a number of Wikipedia articles on logic including sections 2-8 of "Boolean algebra" and all of "Boolean algebras canonically defined". He is currently working on model complexity of global climate.

**Hilary Priestley**, University of Oxford

Hilary Priestley is Professor of Mathematics (Emeritus) at the Mathematical Institute, University of Oxford, and a Senior Research Fellow at St Anne's College. She received her DPhil from the University of Oxford for a thesis which included the duality for distributive lattices now known as Priestley duality. Her research has focused on duality theory and its applications, principally for lattice-ordered algebras, and on connections with, in particular, lattice theory, universal algebra and domain theory. She is the author of three textbooks, including Lattices and Order, coauthored with Brian Davey.

**Stevo Todorcevic**, University of Toronto and CNRS

Stevo Todorcevic was educated at the University of Belgrade where he received a B.S. degree in 1977, a Master degree in 1978, and a Ph.D in 1979. He is known for his Ramsey-theoretic approach to mathematical problems, the side-condition method in Forcing, the invention and development of walks on ordinals and their characteristics, and other research that bridge between different areas of mathematics. In 2012 he won the CRM-Fields-PIMS prize for these research contributions.’
