Associate Professor

Office: S750

​Dr. Cahoy is an associate professor in the Department of Mathematics and Statistics.  He has been teaching statistics courses (and occasionally some math courses) ranging from the freshman level to the graduate level. Before joining UHD in 2017, he was a faculty member at Louisiana Tech University.   His primary areas of interests include modeling count data,  the analysis of large data sets,  statistics education, and the application of statistics to problems in engineering and medicine.  His work has been published in numerous domain-specific and/or statistical journals. He likes to play basketball or tennis in his spare time.
