About

Darren Brouwer is Professor of Chemistry at Redeemer University in Hamilton, Ontario where he teaches chemistry and environmental science, carries out research on developing new methods for structure determination of materials, works with students on monitoring water quality in local watersheds, and ponders the relationships between Christian faith, chemistry, culture making, and creation care. He has studied at Redeemer University College (BCS), University of Guelph (B.Sc.), University of British Columbia (PhD), and Regent College, has held research positions at the University of Southampton and the National Research Council of Canada, and is an adjunct professor in the Department of Chemistry and Chemical Biology at McMaster University.

Research Interests

• Developing project based learning approaches for chemistry and environmental science

Current Research

Understanding the atomic and molecular level structure of materials is of fundamental interest in chemistry and materials science. By understanding the structure of materials, a greater understanding of their functions can be developed. Nuclear magnetic resonance (NMR) spectroscopy, a close cousin to magnetic resonance imaging (MRI) that many are familiar within a medical context, is a powerful tool for elucidating the structural features of materials. I am particularly interested in exploring the ability of NMR spectroscopy to be used for crystallography – the determination of crystal structures – by which the atomic arrangement of materials can be determined.

I am also very interested in local environmental issues and developing ways for our students to engage and address these local issues through project-based learning in our classes, senior research projects, and summer research opportunities. Over the past few years, our analytical chemistry and environmental science classes have been carrying out water quality monitoring projects of a local highly urbanized watershed that drains into an ecologically important wetland, finding that there are quite clear signs of sewage contamination and nutrient pollution. In addition to learning lots about analytical and environmental chemistry, we have been engaging with the City of Hamilton and local environmental stakeholders to find ways to address this problem.
