Teaching Responsibilites

Survey of Chemistry (CHEM 103) This course is designed to provide health science and liberal arts students with a general overview of basic chemical concepts. (Last taught Fall 2010).

General Chemistry (CHEM 105 - 106) This course covers all the basic concepts of chemistry. The concepts at this level can be reinforced nicely through use of examples which relate chemistry to environmental, health and industrial problems. (Last taught 2000).

Inorganic Chemistry (CHEM 253) This course covers the structure and bonding of inorganic compounds with emphasis on molecular symmetry, d-metal complexes and catalysis. (Last taught 2007).

Advanced Inorganic Chemistry (CHEM 453) This course covers the structure, properties, reactions, and bonding of main group, d and f elements with emphasis on metals and solid state chemistry. (Last taught 2008)
