Dr. Alastair N. Cormack, the Van Derck Frechette Professor of Ceramic Science, is the Founding Dean of the Inamori School of Engineering.

Dr. Cormack, who joined the AU faculty in 1985 and was promoted to the rank of professor in 1992, served as associate dean for graduate programs in the School of Ceramic Engineering and Materials Science from 1991-92, and then served a five-year term as dean, from 1992-97. He served as director of graduate programs for the school from 1998 to 2003, when he was appointed as interim dean of the newly formed School of Engineering prior to accepting the full-time appointment in 2004. He returned to the faculty in 2009.

Considered to be among the leading researchers today in the field of computer modeling of materials, Dr. Cormack focuses on the atomic-scale physics and chemistry of materials, particularly ceramics and glass. He uses computers to model the way in which atoms are arranged in solids, and how that arrangement of atoms affects their properties. He is a frequent lecturer on the topic, invited to speak at conferences, colleges and universities around the world.

Dr. Cormack is a Fellow of the American Ceramic Society, the Society of Glass Technology, the Royal Society of Chemistry, and the Mineralogical Society (United Kingdom). He is also a Chartered Scientist and a Chartered Chemist in the UK.

Areas of Concentration
We employ computer-based atomistic simulations to tackle problems in inorganic materials science. Both classical and quantum mechanical molecular dynamics and static lattice techniques are employed, as appropriate. Two major themes form the basis of our research. The first concerns the structure and properties of silica based glasses. Here we are interested in, on the one hand, how the structure governs ion transport mechanisms, and, on the other hand, how it controls the mechanical properties of glass, particularly its strength. The second area focusses on non-stoichiometry and defect structure in crystalline materials. Here also, there is an emphasis on how the defect structure influences ion transport. A common element to both themes is understanding the influence of composition on the atomic or nano-scale structure and, consequently, the reactivity of the material.
