Dr. Craig Hoag
Associate Professor of Chemistry:
Physical Chemistry I and II, Introductory Chemistry II
Craig Hoag grew up in Colorado, most closely identifying with living in the mountains just west of the Denver/Boulder area. While growing up in Colorado, he enjoyed camping, hiking, climbing, fishing, skiing and marksmanship, along with many other outdoor activities. After a tour in the Marine Corps, he attended Metropolitan State College of Denver, where he received his Bachelor of Science in Chemistry. He then went to Gainesville, Florida to attend graduate school at the University of Florida. There, he received his Masters of Science in Physical Chemistry/Radiochemistry and then his Ph.D. in Physical Chemistry.
Craig is married and spends most of his off-time with his family. He likes to camp, hike, fish, canoe and other outdoor activities that can be done with his family.
Dr. Hoag’s research interests are mainly in Chemical Kinetics. He has been looking at the oxidation of IrCl63- by Br2 and ClO2 using UV-Vis spectroscopy and his Stopped-Flow apparatus. He has also been studying the oxidation of Congo Red dye and Amaranth dye by ClO2 using UV-Vis spectroscopy. This research took a turn toward studying the ionic strength effects of stacking of these dyes (mostly Congo Red).
Dr. Hoag encourages his students to take part in research at the earliest opportunity.
