Chemistry is a diverse discipline, involving substances in every aspect of life what we see, eat, smell, touch, and taste every day. With an equal emphasis on theory and practical work, Waterloo's Chemistry undergraduate and graduate programs prepare you for a growing number of dynamic career options. You could be searching for the roots of crippling diseases, developing cancer-fighting drugs, or assessing environmental damage. Research in chemistry encompasses a broad range of topics relevant to life and environmental sciences, to the development of new materials and nanotechnology, but also to improving our fundamental understanding of the world surrounding us. The M.Sc. and Ph.D. programs in Chemistry and Biochemistry at Waterloo offer exposure to world-class research on many subjects including the core areas of analytical, biochemistry, inorganic, materials, nanotechnology, organic, physical, polymer and theoretical chemistry. Our programs prepare our graduate students for fascinating careers in the industry, government and academia.<br><br>Internally contracted multireference coupled cluster method and normal-order-based automatic code generator .
