Associate Dean, Dr. Bob Lemieux

Dr. Bob Lemieux has been appointed Associate Dean in the Faculty of Arts and Science from January 1, 2013 to June 30, 2015.

Dr. Bob Lemieux received his B.A. degree in 1984 from Colgate University in Hamilton, NY, where he studied chemistry and played varsity football for the Raiders.  He received his Ph.D. degree in 1989 from the University of Illinois at Urbana-Champaign under the supervision of Peter Beak, and then carried out postdoctoral studies at Illinois under the supervision of Gary Schuster.  In 1992, he joined the Chemistry Department at Queen's University as Assistant Professor.  He was promoted to Associate Professor in 1998 and to Professor in 2001. He served as Acting Head of the Chemistry Department from 2006 to 2007, and Head from 2007 to 2011.  He also served as Acting Associate Dean in the Faculty of Arts and Science from 2011 to 2012.

The overarching theme in Bob’s research is chirality, and how it propagates in the condensed phase via self-assembly to form materials with chiral bulk properties. His research program bridges the diverse fields of organic synthesis, physical organic chemistry and condensed matter physics. Such an interdisciplinary approach allows his research group to draw important correlations between the molecular structure of liquid crystalline materials and the macroscopic bulk properties they exhibit.  His main research interests lie in the induction of ferroelectric properties in smectic liquid crystal phases using dopants with novel chiral core structures.  The work on ferroelectric liquid crystals (FLC) induced by axially chiral dopants has led to the discovery of an interesting chiral amplification phenomenon, which may prove useful in the formulation of FLC mixtures for high-resolution display applications, and is now being applied to the development of chiral mesoporous organosilicates, in collaboration with Dr. Cathleen Crudden.  More recent work has focused on developing a new design strategy for smectic liquid crystal hosts with ‘de Vries-like’ properties, which undergo a transition from the orthogonal smectic A phase to the tilted smectic C phase with minimal layer contraction—a crucial requirement for defect-free FLC displays.

Bob was one of the inaugural recipients of the Queen's Chancellor's Research Award in 1999; he also received an Ontario Premier’s Research Excellence Award in 2000 and the Samsung Mid-Career Award from the International Liquid Crystal Society in 2012. His teaching in the Chemistry Department was recognized by the Queen's Chemistry Graduating Class Award for Teaching Excellence in 1997 and 2007, and the W.J. Barnes Award for Teaching Excellence from the Queen’s Arts & Science Undergraduate Society in 2005.
