Research in the Klassen Lab focuses on enabling technologies for functional glycomics and disease diagnostics. We are developing analytical tools, based on state-of-the-art mass spectrometry, to accelerate the discovery and characterization of biologically-relevant glycan interactions. We exploit this knowledge to gain a greater understanding of the role that glycans play in human health and disease and aid in the development of new therapeutics. We are developing powerful new tools to characterize the activity and substrate specificity of carbohydrate-active enzymes (CAZymes) and translate these insights into new diagnostics for diseases such as cancer and neurodegeneration. We are also developing mass spectrometry-based tissue imaging tools to uncover the complex relationships between diseases and glycosylation.

CHEM 102 - Introductory University Chemistry II

Rates of reactions, thermodynamics and equilibrium, electro-chemistry, modern applications of chemistry. Prerequisite: CHEM 101.

CHEM 373 - Physical Properties and Dynamics of Chemical Systems

A continuation of CHEM 371 in which the physical properties of chemical systems and the dynamics and energetics of chemical processes are discussed. Topics include: colligative properties; electrochemical cells and ion activities, implications for ionic equilibria; kinetic theory and transport properties of gases and liquids; surfaces and colloid chemistry; reaction dynamics, detailed mechanisms of chemical reactions, catalysis. The emphasis will be on the development of principles of physical chemistry and their application to properties and processes of interest to chemists, biochemists, and engineers. Note: This course may not be taken for credit if credit has already been received in CHEM 273 or 275. Prerequisite: CHEM 371 or 271.
