Dr. Crackel was born and raised in South Dakota. He obtained his B.S. in Chemistry from South Dakota State University in 1980. He finished his Ph.D. in Physical Chemistry from Iowa State University in 1987. He joined the faculty at Minot State in the fall of 1986. His teaching responsibilities include a variety of undergraduate chemistry courses at the introductory and advanced level as well as graduate courses for science teachers. His research interests are in the areas of absorption spectroscopy, environmental chemistry, studies of methamphetamine contamination, and chemical education. He has worked on projects with a number of undergraduate students and science teachers working on their Master of Arts in Science Teaching. He enjoys making bad chemistry jokes and has worked with the Beta Gamma Phi Science Club and the regional Science Olympiad for over 30 years.
