Dr. Paul Jasien

Dr. Jasien's major research interests are listed below:

(1) Applications of computational quantum chemical techniques to elucidate molecular structure, energetics, and intermolecular interactions. One recent area of investigation is the elucidation of intermolecular halogen-bonding interactions and their role in modifying chemical reactivity and molecular properties.

(2) Student conceptual understandings of topics in General Chemistry and development of guided-inquiry exercises for the classroom and laboratory. These interests also tie into his interest in the preparation of middle and high school physical science teachers.


Ph.D. Physical Chemistry, University of Illinois, Urbana-Champaign, 1984
