His specialty is physical chemistry, which he teaches at the undergraduate and graduate levels. About 50 percent of his teaching is in general chemistry: chemistry for nonscience majors, GOB, and general chemistry for science and engineering majors. In addition to this text, he is the author of a math review book for general chemistry students, a physical chemistry textbook with accompanying student and instructor solutions manuals, and two books on spectroscopy (published by SPIE Press). He is coauthor of a general chemistry textbook (with Dan Reger and Scott Goode), whose third edition was published in January 2009. His publication list includes over 220 items, evenly distributed between research papers and articles of educational interest.

Dr. Hill was Professor Emeritus from University of Wisconsin-River Falls. An organic chemist, he has had more than 50 publications in refereed journals, most of which have an educational bent.
