Spring (alternate years, even)
Credit: 3 graduate 
Instructor(s): Deborah Keil

Course Description

The primary goal of this course is to provide an understanding and knowledge of the mechanisms of toxicity including the role of metabolism in enhancing and reducing toxicity and the effects of toxicants on major organ systems. Students are expected to learn the following fundamental toxicological concepts: major classes of toxicants, absorption, distribution and storage of toxicants, biotransformation and elimination of toxicants, and effects of toxicants on major organ systems. Clinical and environmental agents specific to human health and an introduction to risk assessment of exposure to toxicants will also be discussed.

Meeting Place and Times

Participants log in to the course at a time of day that best fits their schedule. It is necessary to connect at least 4 - 6 times per week and spend 8 - 10 hours per week while the course is in session, either online or offline working on course related assignments, to stay current and successfully complete this 3 credit graduate course.


Deborah Keil, PhD. Currently, I serve as an Associate Professor in the Department of Microbiology and Immunology at Montana State University. Prior to this, I served in the Department of Pathology in the School of Medicine at the University of Utah, Department of Medical Laboratory Sciences at UNLV, Research Toxicologist at NIOSH, Morgantown West Virginia, and Assistant Professor at the Medical University of South Carolina in Charleston, SC. Over the past 20 years, I have acquired competitively-funded research in the disciplines of clinical laboratory science, immunotoxicology, developmental toxicology, and human health risk assessment. Educational achievements include a B.S. in Clinical Laboratory Science from Western Carolina University, Cullowhee, NC and a Ph.D. from Mississippi State University (1996). I am also a licensed Medical Laboratory Director in the state of Nevada (2007-current), Diplomate of the American Board of Toxicology (2006) and served on the Board of Directors of the American Board of Toxicology (2012-2016).
